Saturday morning Sheba and/or Nina picture

So I'm sure you're all dying to know how Sheba's been, since her injury of unknown origin from last week.

Well. The injury happened on or around Wednesday the 15th, she saw the vet on Thursday the 16th, and she seemed to be hyper enough while "resting" with the pain meds that we tried not giving them to her on Sunday the 19th. Which made her grumpy, so we resumed them, and then tried going without a couple days later, on the afternoon of the 21st. We couldn't tell any difference in her behavior, so she's been without the painkillers since Tuesday morning, and whatever it was appears to have resolved itself. She's not going to be chasing tennis balls for a few more days, just to be sure, but I think the problem is basically over. It's a little frustrating not to know what it actually was, but if it's over, I will take that and be quite happy with it, thank you very much.

The photos are from Wednesday, when Sheba accompanied the husband and me into Iowa City and we stopped at what Google Maps calls "Sand Lake Park." It's just a man-made lake or pond, a little over 1000 feet (305 m) long and about half as wide. Nothing terribly special, but I can recognize a photo opportunity when one smacks me in the face like this.

Random plant event: Aloe x humilis

These pictures are from the ex-job, in early January. They've never exactly had an ID for the plants, but they were sold as "hedgehog" Aloes, and there's a plant I've seen elsewhere, sold as A. x humilis 'Hedgehog,' which I'm guessing is the same plant even though that specimen was larger. So that's what I'm calling them for purposes of the post, though the name 'Blue Elf' has also been proposed as an ID. In any case, I bought one of them from the ex-job a couple years ago, and it's been a good houseplant. No pests, propagated a few times, no abrupt declines -- if it can make it through another eleven months without any major problems, it'll qualify for All-Star status.

Aloe x humilis 'Hedgehog,' according to the tag.
I, of course, have never gotten flowers on my plants indoors. Which is a shame -- even a bit after their prime, as in these pictures, the flowers are still pretty. But then, most of my Aloes don't bloom; the only one that ever did so with any consistency was A. 'Doran Black,' and the parent plant of that one disintegrated on me about a month or two ago. I've restarted what few offsets I could salvage, but it'll be a long time before it's back to blooming size.


I've gotten flowers on A. 'Grassy Lassie' once indoors, too, though they didn't photograph well and were gone by the time I figured out that they hadn't photographed well. Not that the flowers are really the point, for any of my Aloes and Aloe hybrids. They're just nice.

[Exceptionally] Pretty pictures: transmitted light -- Part XLVII

Catch-up week continues. This particular batch has an unfortunate tendency toward greenish-yellow, which I fear will clash with the background, but this is the set that was queued up and ready to post, so this is the set you get. Wear eye shielding if you feel it's appropriate to do so.¹

(The previous transmitted light posts can be found here.)

Commelina communis. Is it weird if I admit that I'm looking forward to seeing the first C. communis sprouts coming up outside this spring? I mean, I know it's a weed and all, but I really enjoy the flowers.

Aglaonema 'Silver Queen.' I recently cut my 'Silver Queen' back, and am trying to root the tops in soil. This had to happen -- the plant was too tall and gangly -- but the stumps haven't resprouted yet, and I can't tell whether the tops are rooting, so I'm a little anxious about the whole thing. It's a variety that used to be all over the place but doesn't seem to be anymore, so if it doesn't survive the beheading, I may have trouble finding a replacement.

Cordyline glauca, dying leaf. My goodness, some of these photos are ancient: I only realized it because I haven't had a Cordyline glauca for nearly a year now.

I like this picture. It has something to do with the colors, but I'm not sure how to explain.

Arctium sp.

Philodendron 'Congo Green.' The line across the top of the photo isn't a shadow; it's actually part of the leaf coloration. Because Philodendron leaves start out curled up (or at least those of 'Congo Green' and a lot of other Philodendrons do), a freshly unfurled leaf will sometimes be darker on the portion of leaf that was exposed to light during development, and lighter on the part from the interior of the spiral, which is what's happened here.

Mahonia aquifolium.

Alpinia zerumbet variegata. Alas, this is not turning out to be as easy to care for indoors as I'd thought it would be. I still have one, and if it continues to live, I'll continue to keep it, but if it dies on me, I don't think I'm going to try the plant again.

Aeschynanthus longicaulis. On the other hand, A. longicaulis is remarkably easy and vigorous, at least for me. Tons of flowers this winter, too, which would be easier to get excited about if the flowers were more colorful. But still. Hard to dislike a plant that's so easygoing.

Quercus sp., autumn. Either this one or the next one is my favorite from this batch. I like both the geometry and the colors on this picture; I want to say it reminds me of an afghan my grandmother crocheted.

Caladium 'Fire Chief.' This is a little more BANG! POW! In your face! than the other, but Caladium pictures tend to be that way.

¹ It may surprise the reader to know that the Preview function in Blogger does not render the post as it will appear on the blog: the words and pictures are all present, and in the right sizes and positions relative to one another, but the background is plain white, and there's no sidebar. This isn't a huge deal, but sometimes not being able to view an actual preview means that I post pictures that clash uncomfortably with the background, or a video gets posted that overlaps part of the sidebar, or things of that nature.

Other: "Botanica"

I'm not sure what to do with this exactly, but I got an e-mail from a reader about it, and it does appear to be the sort of thing I should report to the rest of y'all, so here we go.

WHAT: a (live!) drama called "Botanica," written by Jim Findlay. I found it pretty hard to get a handle on, because the reviews and promotional materials seem to be trying very hard not to say much about it, but the short synopsis from the "Botanica" website reads:

The narrative of BOTANICA tracks the scientific experiments and the developing relationship between two botanists who are sealed in a research facility — a human terrarium. They share their habitat with the janitor/plant caretaker, who seems unremarkable except for his curious habit of reading aloud to the plants late at night the most salacious sections of books by Bataille and Aragon, along with his own self-penned blue poetry. Initially the experiments seem to demonstrate an astonishing scope of plant consciousness, but eventually the botanists hit a dead end. They decide to bring the janitor into their research. The introduction of this human subject reinvigorates their investigation but leads to unforeseen consequences and unleashes a flood of unusual findings that end in chaos as the constraints of science and social norms are overturned.

Or you can read the New York Times review.

WHAT?: I don't know. Apparently it's experimental, and artistic or something. Also there's some plant-fucking involved, though you should have assumed that when I said "artistic."

UM, OKAY. WHERE?: 3LD Art & Technology Center (80 Greenwich St., New York City)

WHEN?: February 22-25, 8 PM.

TICKETS: Can be purchased here, and are $10-30.

SERIOUSLY?: I realize most of my readership isn't going to be able to see this, and only some of those who are able are going to want to, but it seemed like the sort of thing I should say something about, because obviously one is curious. I mean -- plant-fucking? How does that even work? In any case, if any reader happens to be in New York later this week and decides to attend, I insist that you report back and explain to me what it is that you saw and whether it was any good.

Random plant event: Billbergia 'Foster's Striate'

Gentle readers,

This would be a good week for you not to expect too much from me, blogularly speaking. Everything's fine, but the combination of Sheba's mysterious pain last Wednesday and my own all-day headache on Sunday has thrown off my delicately-balanced blogging and watering routine, so I just don't have the usual amount of time to spend blogging.

That said, here's a thing that's happened here lately:


The plant is Billbergia 'Foster's Striate,' which I've had since a reader trade last May. It's been well-behaved: no pests, no excessive leaf drop, no burnt tips or margins, no loss of variegation. This isn't the first new offset since it got here, but it's the first one I've noticed so early in development. Mine hasn't bloomed yet, but it's my understanding that the flowers are similar to those of B. nutans.

If you're interested in having one of your own, to love / pet / squeeze / call George, check with Grower Jim at Garden Adventures; he is selling some, or at least was at one time. (1 for $4, 2 for $5, plus shipping. PayPal. U.S. only. No shipping to HI, AZ, CA, TX, LA, MS, NC. Other restrictions may apply; see link for details.)

Pretty picture: Masdevallia Caraway Moon

I don't really see what's caraway-like (or moon-like, for that matter) about this flower, but that probably just shows I'm a dull, uncreative person.


Google has no records of an orchid by the name of Masdevallia Caraway Moon. (Image searches for "Caraway Moon" bring up lots of images of shoes; I declined to investigate the reason, but I suppose someone might have named an orchid for a shoe? Or vice-versa?)

Saturday morning Sheba and/or Nina picture

(Background. I couldn't locate the original Boston Globe version of the story on-line.)

Of course there's a website.

Sheba had a rough week this week; on Wednesday night, she started acting like she was in pain -- random yelping, shaking/trembling, reluctance to go up or down stairs, sort of an overall slow/lethargic thing. So we took her to the vet on Thursday, and he gave us painkillers for her and told us to try to keep her as inactive as possible for the next week or so and see if things were getting back to normal. I got the impression that he's leaning toward a pinched-nerve/pulled-tendon sort of theory, that it's not anything that would require further intervention, but we have to wait and see.

So if you've donated money recently, that's where most of it went (I also got a couple more shop lights, a week or two ago), and Sheba says thank you.

Or, she would say thank you, if she were awake and spoke English. So far, the painkillers (Rimadyl) mostly seem to make her sleepy. And her English has never been very good.

List: Houseplants Native to China

Most of the caveats from this post also apply here: don't use this list for situations in which getting a plant's native range wrong might result in someone's death, I'm mostly relying on GRIN for my information, native ranges aren't always known with any kind of certainty so even the best available information may not be correct, and so forth.

For this one, we're talking about China. There will be a lot of overlap between this list and the ones for Eastern Asia (including Japan), India, Indo-China, Malesia, and Australia, just because China's sort of right in the middle of all those and plants respect political boundaries even less than people do. I apologize for being unable to find a clear public-domain map of the area; I looked for a long time, and found all kinds of stuff, none of it quite what I wanted. Instead, I have to do two different maps, one for the actual political divisions of China itself:


And the other to show where China is relative to the other countries I'll be mentioning (particularly note the locations of Korea, Japan, Taiwan, Vietnam, and Burma, as there will be a test later¹):

I've circled the Ryukyu Islands because 1) they're going to come up a lot and 2) the original map didn't have them labeled.
Obviously not everybody's going to care about specifically where in the country the different plants come from, but I'm trying to provide the best information I've got for those people who do, 'cause that's the kind of guy I am.


Aglaonema cvv. (shown: cv. 'Emerald Bay') (Chinese evergreen) are usually man-made hybrids, or sports, or sports of hybrids, and consequently don't "really" come from anywhere, but a lot of the species which provided the raw material for the hybrids are from Indo-China (Cambodia, Laos, Thailand, Vietnam) and Malesia (Indonesia, Malaysia, Philippines), with a few as far north as China and as far west as India.


On-line sources disagree about the origin of Aspidistra elatior (cast-iron plant), with some saying it's from Japan and naturalized in China and others saying it's from China and naturalized in Japan. Either way, it's in the right neighborhood for what we're talking about, and GRIN says China but not Japan, so we're going to go with that until I have good reason to change it.


Chirita cvv.² are from within the general India-China-Indonesia triangle; a lot of the plants out there are man-made hybrids (like 'Deco,' shown), but a substantial chunk of the species are from southern China.


Cycas revoluta (sago palm) is from the Fujian province,³ along the southeast coast of China, as well as the Kyushu and Ryukyu Islands in southwestern Japan.


Eriobotrya japonica (loquat) is from the Hubei and Sichuan provinces of China, as well as Taiwan and the Japanese islands of Honshu (the main island of Japan), Kyushu (SW of Honshu), and Shikoku (east of Kyushu and south of Honshu).


Ficus pumila (creeping fig) is found in southeast China.


Pilea peperomioides (Chinese money plant, Chinese missionary plant) is from the Yunnan province of China, which is in the southwest corner of southern China (it borders Burma⁴).


Rhapis excelsa (lady palm) is from southern China and Japan.


The range of Saxifraga stolonifera (strawberry begonia) largely overlaps with that of Ficus pumila, but also extends to Japan, Taiwan, and Korea.


Selaginella uncinata (peacock spikemoss, blue spikemoss) is from southern China.

For the recommends:

I love Aglaonemas; I don't do well with the rhizomatous types like A. brevispatha, but all the upright cane-type ags and I get along famously.

Rhapis excelsa tolerates me. I'm not sure if we actually like one another, but it's put up with a lot of crap from me and is still alive and growing.

Saxifraga stolonifera and I are going through an extended rough patch at the moment, but mostly we've gotten along; I suspect that our problems were mostly my fault, not the plant's. We'll see if I can turn that around. Either way, the plant was good enough, for long enough, that I don't have a problem recommending it, even if mine aren't so great at the moment.

The anti-recommend is tough, because I've had bad experiences with the Cycas, Pilea, and Selaginella. Cycas revoluta seems to do well for most people, though (I think my problem was possibly fertilizer-related), so I won't choose it. The Pilea was never happy with me, and even though it lived here for fourteen months, it was declining slowly the entire time. I don't know what happened. I wouldn't recommend it to other people, but it's probably still not as bad as Selaginella, which I don't recommend to anyone who doesn't have an enclosed container of some kind to keep it in, because they're very serious about their moisture levels. Also, I believe I've managed to kill this particular Selaginella despite having an enclosed container for it, which just goes to show you how awesome I am at killing things.

Not pictured:

• Aeschynanthus longicaulis is native to the Yunnan province of China, as well as Burma, Thailand, Vietnam and Malaysia.
• Alocasia spp. (elephant ears) in general are from Indo-China (Laos, Thailand, Vietnam) and Malesia (Brunei, Malaysia, Indonesia, Singapore, Papua New Guinea, Philippines), but some ranges extend as far north as southern China (Yunnan and Guangdong provinces).
• Alpinia zerumbet (torch ginger) has a fairly wide range, from Japan westward into northeast India and south through Indo-China and Malaysia, which includes the southern provinces of China.
• Ardisia crenata (coral berry) has a pretty substantial range in southeast China, but it's all over the place (Japan, Korea, Taiwan, India, Burma, Vietnam, Thailand, Philippines, Malaysia).
• The GRIN-official range of Asplenium antiquum (bird's-nest fern) is odd and patchy, and sort of runs along the boundary between the East China Sea and the Philippine Sea. Beginning at Hong Kong, the range goes northeast through Taiwan and Japan into South Korea. I have no idea why A. antiquum has never been able to make a go of things on the mainland, but this may explain why they always turn on me when I try to grow them here in landlocked Iowa.
• Aucuba japonica (spotted laurel, Japanese laurel, gold-dust plant) is, as the botanical name suggests, primarily from Japan, though there are also some in the Zhejiang province on China's east coast.
• Weirdly, Carmona sp. ("fukien tea") is not from China's Fujian province, at least not according to GRIN, but it is found in the southern part of Guangdong (about as far southeast as one can go in China) and Hainan (as far south as you can go in China). I wonder who fucked that one up. It's also found in the Ryukyu Islands of Japan, Taiwan, west to India and Sri Lanka, south as far as Queensland (Australia), and through Indonesia and Malaysia into the Philippines.
• Cissus discolor (begonia vine) is naturally found in south central China, in the provinces of Sichuan and Yunnan, as well as from India eastward to the Philippines.
• Colocasia spp. (elephant ears) are from south and southeast China, south through Laos and Vietnam, Malaysia and Indonesia. C. esculentum specifically has been so widely cultivated that we don't know where it came from, though it's a pretty safe bet that it originated somewhere in that general area too.
• Cymbidium cvv. are largely hybrids, made by aliens from the seventh moon of the planet Zecuponia III and introduced to earth via an underground network of florists and hobbyists who are actually disguised aliens, secretly observing humanity in anticipation of the day when they can destroy all humans. Why they need to observe first, I have no idea -- apparently they think there's something about us that isn't obvious on the surface.⁵
• GRIN was unusually non-specific about the distribution of Cyrtomium falcatum (holly fern); it looks like it's basically the southeast coast of China, north to Japan and south to Vietnam, plus a population all by itself off in India somewhere.
• Various species of Davallia (rabbit's-foot fern) occur in different spots all over the world; at least one makes its home in southeast China, though I don't know which species.
• Dendrobiums are mostly man-made hybrids at this point, though some species specimens are out there to be had if that's what gets you excited. If you're looking in China, check the south and southeast provinces (Yunnan, Guangxi, Guangdong, Guizhou, and all that); otherwise you can find hot Dendrobium action from south China all the way to northern Australia, from India to the Philippines.
• Dioscorea bulbifera (air potato) is another one with a native range that's just a mess: you start in west Africa with Guinea, the Ivory Coast, Ghana, Liberia, and all those along that edge there, including landlocked Burkina Faso, to where the coastline begins to curve to the south at Cameroon and Nigeria, then stop. Go to the east side of Africa and pick up Tanzania, Uganda, and Madagascar, as well as Mauritius and Reunion Island, to the east of Madagascar. Then pick up again at Sri Lanka, just off the southern tip of India, north and east through India, Bhutan, and Nepal, and from there it's all the usual places: south and east China, all of Indo-China, Malesia (Indonesia, Malaysia, Papua New Guinea, Philippines), south into north and west Australia. I don't know if it's safe to assume that there might be other spots that GRIN doesn't mention, that fill in the gaps in the range (like maybe central Africa, if nothing else), or if it really has a bunch of isolated populations like this.
• Of course some Drosera spp. (sundews) are from China; Droseras are basically everywhere. Seriously. I'm not even going to try.
• I'm not going to try to describe the natural range of Ensete and Musa spp. (banana) either. There are both Ensete and Musa species native to China, some as far north as Tibet (Xizang) but mostly in the same southern and eastern part of China that everything else is from.
• Ficus benjamina (weeping fig, ficus tree) has a large range stretching from northeast Australia all the way north to south and east China, west to India, east to the Solomon Islands, and covering everything in between (Indonesia, Papua New Guinea, Philippines, Indo-China, etc.).
• Ficus microcarpa (Cuban laurel) has basically the same range as F. benjamina, though it extends a bit further north (to the Ryukyu Islands of Japan) and a bit further to the southeast (Palau, New Caledonia, etc.)
• Gardenia jasminoides (gardenia) is native to the eastern edge of Southeast Asia. From north to south: Japan, Taiwan, China, Vietnam.
• Gloriosa superba (glory lily, gloriosa lily) is another species that splits its time between Africa and Southeast Asia. It only just barely qualifies for this list; GRIN says it's native to a bit of southern Yunnan province (which is in southwest China). Most of its Asian range is south and west of that, though: south through Indo-China and Indonesia, west until you hit India. The African part of the range covers most everything down the east side of Africa (Ethiopia / Somalia / Sudan, Uganda / Kenya / Tanzania, Mozambique, Botswana, South Africa, and a little ways up the east side, as far as Namibia). There's also supposed to be a little population all by itself in Senegal, which is as far to the west as you can go and still be on the African continent; I sort of wonder if the Senegalese bit is an error on someone's part.
• Hoya carnosa is native to southern China, as well as Taiwan, the Ryukyu Islands of Japan, and Kyushu (Japan), India, Vietnam and Malaysia. I don't know if the Indian population is actually separate or if part of the range was left out.
• A few other Hoya species claimed to be native to China: Hoya chinghungensis, Hoya dasyantha, Hoya fungii, Hoya globulosa, Hoya griffithii, Hoya juangoiana, Hoya lii, Hoya lyi, Hoya manipurensis, Hoya mengtzeensis, Hoya motoskei, Hoya multiflora,⁶
Hoya ovalifolia, Hoya pandurata, Hoya picta, Hoya pottsii, Hoya salweenica. I didn't dig into the details on most of these, but they were on the list; check 'em out yourself if you're interested.⁷
• Jasminum officinale is a welcome change of pace -- it's actually from western China (Guizhou, Sichuan, Xizang/Tibet, Yunnan) and its range extends to the west from there (east to west, in order: Bhutan, Nepal, India, Pakistan, Tajikistan, Afghanistan, Iran, Georgia, Turkey).
• Jasminum polyanthum is strictly Chinese, from the south/central provinces of Guizhou, Sichuan, and Yunnan. I'm appreciating that one, too, 'cause it's easier to type out. You're totally bored with this by now, right?⁸
• Lemmaphyllum microphyllum is an oddball epiphytic fern; GRIN didn't have a listing for it, but other sources suggest a range from Korea south through Japan, Taiwan, and the Philippines, either stretching west into India or with a separate population in India: I never know if my sources are just being lazy with this sort of thing or if there are actually isolated populations of plants all over the place.
• Liriope spicata (lilyturf, monkeygrass) is another down-the-coaster: Japan, Taiwan, most of China, south into Vietnam.
• Livistona chinensis (Chinese fan palm) is also a down-the-coaster: Japan, Taiwan, south China.
• Ludisia discolor (jewel orchid) comes from the southern coast of China, south through Indo-China (Burma, Thailand, Vietnam), Indonesia, and Malaysia.
• Murraya paniculata (orange jasmine, orange jessamine) can be found naturally in the southern couple rows of provinces of China, east to Taiwan and the Philippines, west to India and Sri Lanka, south as far as the north coast of Australia, and some of the western and southwestern Pacific islands. Plus, obviously, all points in between (Indo-China, Indonesia, Malaysia, Papua New Guinea, and so forth).
• Nandina domestica (heavenly bamboo) is from China and Japan; I don't know what parts of China specifically, but with Japan, it's the three southern large islands (Honshu, Kyushu, and Shikoku).
• Neofinetia spp. weren't in GRIN, but another source puts them in east Asia, specifically Korea, Japan, and China.
• I don't know if anybody tries to grow Nephrolepis hirsutula (scaly sword fern) indoors or not, but GRIN says Guangdong, China is part of the natural range, along with Thailand, Malaysia, and the north coast of Australia.
• I've gotten the general impression that Nerium oleander (oleander) is primarily a Mediterranean and west Asian species, but GRIN puts its native range along an east-west line that stretches from Morocco, in northwest Africa, through north Africa, the Middle East, and India, with a bit in Yunnan province of southwest China.
• GRIN claims Origanum spp. (oregano) are native throughout Europe, south and east into Turkey, Iran, and Georgia, and then small areas of India and China (specifically the provinces of Sichuan, Xizang/Tibet, and Yunnan, all in southwest China). Whether this refers to a fragmented range, multiple species, or inadequate data is unclear.
• Osmanthus fragrans (fragrant olive, sweet olive) is at home from northeast India, Nepal, and Bhutan east into northern parts of Burma/Myanmar and north Thailand, and southwest China. GRIN also lists the southern part of the island of Kyushu, in Japan, but that's a long way from the rest of the plant's range, so I'm not sure what to do with that.
• Paphiopedilum cvv. (slipper orchids) are mainly found in Indo-China, Malaysia, and Indonesia, but some species are found as far north as southern China.
• Pellionia repens (watermelon begonia) is native to Indo-China, west to India, east to the Philippines, south to Indonesia, and north to Yunnan and Hainan provinces in south/southwest China.
• Perilla frutescens (beefsteak plant, shiso) may or may not qualify as a houseplant; it sort of seems like it ought to be possible, but I haven't heard of anyone ever actually growing it indoors. It's found in much of southern and coastal China, though, as well as throughout Indo-China, Taiwan, much of Japan and Korea, northern India, Bhutan, Nepal, as far west as Pakistan.
• The range of Phaius tankervillae (nun orchid) is bounded by southern China and Taiwan on the north, northeast India on the northwest, Sri Lanka on the west, northern Australia on the south, and the southwestern Pacific islands on the southeast, as well as most of Malesia and Indo-China.
• Phoenix roebelenii (pigmy date palm) has a fairly small native habitat, limited to north Laos, northwest Vietnam, and the Chinese province of Yunnan, in southwest China.
• Phyllostachys spp. (bamboo) are all found in China; their suitability as houseplants is questionable, but people do attempt it.
• As I understand things, the natural range of Pilea cadierei (aluminum plant) is even more in question than that of most domesticated plants, because nobody's seen it in the wild for quite a while, but it's believed to have originated in Vietnam, and GRIN says there are some in southwest China (Yunnan and Guizhou) as well.
• I'd warn you not to try Pogonatherum paniceum (house bamboo) indoors, whatever common name marketers are trying to put on it, but Tropicos appears to be claiming⁹ that the natural range extends from Pakistan in the west all the way through India, Indo-China and China, south into Malaysia and Indonesia.
• Polypodium formosana (=Polypodium formosanum) (caterpillar fern, naked rabbit's foot fern) is from China, Japan, and Taiwan, according to Tropicos. ("Formosa" is the Portuguese word for Taiwan.)
• Polyscias fruticosa cvv. (ming aralia) has the whole India / China / Indo-China / Malesia thing going on, plus Fiji in the southeast.
• Pteris cretica (cretan brake fern) is from everywhere, according to GRIN: most of equatorial Africa, south Africa, and Madagascar (plus Algeria, for some reason), western and southern Europe, Turkey, Yemen, northern India, Indo-China, China and Japan. Plus an incongruous bit in Guatemala and southern Mexico, which I'm thinking is maybe a mistake.
• Pteris vittata (chinese brake fern, ladder brake fern) is similar to P. cretica, though without Europe or the Mexico/Guatemala bit. P. vittata is also supposed to be present in the wild in three different Australian states, none of which share borders: Queensland (NE Australia), Western Australia (west), and Victoria (SE Australia). I don't know what's going on there.
• Radermachera sinica (China doll) is native to southern China, Taiwan, and the Ryukyu Islands of Japan, which most sources agree on, plus GRIN adds Vietnam, Burma/Myanmar, and a teeny bit of northeast India.
• Schefflera arboricola (umbrella tree) is from two islands in the South China Sea: Taiwan and Hainan. I expected more, but that's all GRIN said.
• Solenostemon scutellarioides (=Plectranthus scutellarioides, Coleus blumei, coleus): India, China (the SE corner -- Fujian, Guangdong, and Guangxi), Indo-China, the Philippines, and then all points south of that line until you hit the north coast of Australia, more or less.
• The natural range of Tacca chantrieri (bat plant) runs from India and Sri Lanka in the west, to pretty much all of Indo-China, plus Malaysia just to the south of Indo-China and most of southern China.
• (We're almost done!)
• The natural range of Trachelospermum jasminoides (confederate jasmine, star jasmine) pretty much includes everything that touches either the South China Sea or the East China Sea, with two exceptions: Korea, Japan, China, and Vietnam, but not the Philippines or Taiwan. At least, not according to GRIN.
• GRIN says Trachycarpus fortunei (windmill palm, Chinese windmill palm) is found throughout central and eastern China, as well as some of northern Burma/Myanmar.
• Southwest China (Guangxi, Guizhou, and Yunnan) is at the northeast tip of the range for Trevesia palmata (snowflake aralia, snowflake plant), which is primarily an Indo-Chinese (Cambodia, Laos, Burma/Myanmar, Thailand, Vietnam) species. A little bit of northeast India and neighboring countries (Nepal, Bhutan, Bangladesh) are included in the range too.
• Vandas are mostly man-made hybrids these days, but some species occur in Yunnan province, in southwest China. The rest of them are spread throughout a India / Philippines / Indonesia triangle.

Borderline cases:

• Citrus, Citrofortunella, and Fortunella spp. (citrus, orange, kumquat, lime, lemon) are thought to have originated somewhere in the general China / Indo-China / India area, but nobody's really sure, because they've been so widely cultivated.
• Farfugium japonicum 'Crested Leopard' may or may not count as a houseplant. (I've heard of it being done, but never actually seen it or attempted it, so I don't know how well that works out for anybody.) It is, nevertheless, native to Japan, north to Korea, south to Taiwan, and in southeast and central China.
• Hemionitis arifolia (heart fern) isn't included in GRIN, but Exotic Rainforest says "primarily from Laos, Sri Lanka, Vietnam and possibly China, Taiwan and other nations in tropical Southeast Asia." So maybe it belongs on the list, and maybe it don't.
• Hoya kerrii is possibly native to China: one source said China, Japan, and Thailand; another said Thailand and the Philippines.
• Hoya lacunosa cvv. is possibly from south China, according to Google; it's more definitely present in Thailand, Malaysia, and Indonesia.
• Microsorum steerii (oil fern) and M. thaliandicum aren't in GRIN, but both are claimed to be present in southern China, Taiwan, and Vietnam. M. thailandicum is also, as one might expect, found in Thailand.
• Nepenthes spp. (pitcher plants) are mainly from warmer climates to the south of China, but at least one, N. mirabilis, can be found in Guangdong and Hainan, in south China, as well as south through Indo-China, Malaysia, Indonesia, Queensland in northeast Australia, and a few Pacific islands (Micronesia, Palau). I don't know if N. mirabilis is one of the species people try to grow indoors or not.
• Phalaenopsis cvv. (moth orchid) are mostly hybrids, as far as what's available to grow as a houseplant. A few species are supposed to live in parts of China (particularly the large southern island of Hainan), like P. hainanensis (Hainan and Yunnan), P. braceana (Yunnan), P. deliciosa ssp. hookeriana and P. mannii (eastern Himalayas to SW China), and a handful of others, but it's not clear how widespread any of these are in cultivation, and my main source for this is Wikipedia, making it even more doubtful.

¹ Being a product of the U.S. educational system, I was embarrassingly ignorant of a lot of this region before I started working on this post. I'm a little clearer on southeast Asia now, plus I can name, spell, and indicate the approximate location of three and a half Chinese provinces (Fujian, Hainan, Yunnan and sometimes Guangdong), which I couldn't do before.
² The genus is in the process of being taxonomically reorganized, so I'm not sure whether this will be true in the future, or for how long. Try as I might, I can't actually keep up with all of the taxonomic stuff that's going on lately.
³ Fujian is also sometimes rendered "Fukien" when spoken by English-speakers, hence "fukien tea" (Carmona sp.)
⁴ Which is also called Myanmar; whichever name you use for the country will inevitably offend someone, and I, not having any idea about the issue(s) involved and very little motivation to put in the research at the moment, have no idea whose side I'm on. Wikiposedly the U.S. government prefers "Burma," so I'm going with Burma.
⁵ Just checking to see if you're reading this, and incidentally amusing myself a bit -- this gets kind of tedious to type out. Plus I keep having to look at maps. Cymbidiums in fact are mostly man-made hybrids, but the original species are found inside of an India-Korea-New-Guinea triangle, including parts of China but apparently excluding the Philippines.
⁶ Questionable -- the source for this had it as part of a list of Chinese natives but didn't include China on the more specific page for the plant, so I don't know.
⁷ There's also a good chance that some of those names are synonyms for other names on the list.
⁸ Well, suck it up, 'cause we're only up to the letter J.
