Sometimes when I title a post "unpretty pictures," it's a little tongue-in-cheek, and the pictures aren't actually that bad. This is not one of those times, though.
I mean, not that it isn't still interesting. B. pterophyllum is actually sort of fascinating. But pretty it isn't.
It would be a very long project to try to determine whether this is the single strangest orchid I've ever seen, but it's surely a contender, at least. Sort of like an Epiphyllum, but somehow even uglier. At least Epiphyllum have nice flowers.
Sure, I've grown and enjoyed plants whose appeal wasn't immediately obvious, but damn.
