Xylobium variegatum
 

This orchid has non-ressupinated, small flowers, in a relatively big plant; it's very sensitive to fungus on their leaves.

I have never seen or heard about this genus. Looks great, though. :)

Xylobiums are rare in cultivation. I owned a Xylobium squalens once. They came in pretty bad shape and didn't make it (the roots were badly damaged - or rather there weren't any viable roots left). From what I've seen though, they're pretty hardy.

If you're interested in them, they're usually sold by a lot of South American vendors from the orchid shows (Ecuagenera, Orquideas del Valle, Floralia).

Maybe in the future I'll try one again.

I'll definitely keep an eye out for them (they sound like they're worth a try). :)
