I have one more we can't identify. It's in the greenhouse of a local community college, and apparently no one has been able to identify it yet. Have been told it flowers, a red puff-ball like thing, which does not sound at all like an orchid, although the leaves seem very orchid-like (but very wide - probably 2-3 inches). The color of the leaves on the left-hand side is the true color. Many thanks!
Sorry - meant to say "now I need to nail down the species" - not meant to be a directive (to anyone but myself).
