This Dendrobium has been on the blog before, but the orchid show had it again, so I took a picture of it again. 'Cause I'm simple like that. Pretty sure it was the same specimen again, too, because 1) how many can there be in the area? and 2) surely it can't be a coincidence that they had the same annoying, outline-breaking background up behind the flowers this year that they had last year, right?
I did look up the ancestry this time. Spider Lily is a cross of Den. Roy Tokunaga and Den. alexandrae; Roy Tokunaga is a cross of D. atroviolaceum and D. johnsoniae. The flowers, to me, look most like D. alexandrae, though alexandrae is much more heavily freckled.
