Since the Kye servers seem to be down, I'll cross-post here.

I acquired a couple seedlings of C.dolosa in a trade a couple years back
and one has finally bloomed. Nice, but not quite what I expected. I'm
trying to decide if it lies within the variations in this species or is
something else entirely. The flower is 3.5" (9cm) across on a plant that
does look like a walkeriana group type, about 7" tall.
