Photos are attached... it's putting up four new growths, and doing quite well... but I have no idea as to it's classification. It was a gift, and its previous owner hadn't known either...
(I'll probably have to wait for a bloom, I know... but the rhizome is quite distinctive.)
Ross, without flowers it is impossible to ID your plant. Could be something like Bulbophyllum sinapsis but then again it could be one of the Careyanum section species. Patience my man, patience!!
