Fascinating; I have spent over a year in Colombia and have never seen a plant like this one. I would like to know more about it, and know if you have seen any others like it. When it flowers I would like to see pictures and at different angles of the fower.
It does look like some kind of Pleurothallid, but I don't think I've ever seen anything like that cluster of buds. I'll be interested to see it in flower.
