I obtained a
Dendrobium tannii in early February. Imagine my surprise when what I thought were odd leaves turned out to be flowers... My orchid "noob" status writ large!
Anyway, here's a picture of the flowers; you can read more about it and see more pictures (and click through to bigger copies) at my
Orchids on a Balcony blog post, "An Unexpected Treat (and a little science) - Dendrobium tannii".
I believe some people consider this species invalid and would list it as a compact growing
Den. bracteosum, or
Den. bracteosum var.
tannii.
