thanks richard.. this plant is from Borneo.. maybe it is a variation. of Bulb.atratum. did the flowers on your picture opened up like mine?.. thanks again.
hello ªü«O, my plant is from Borneo. rescued from a clearing for oil palm growing by myself..so no doubt about it..
a friend in another forum told me about the reference you mentioned. .the book "A to Z of South East Asian Orchid Species" by Peter O'Byrne where Bulbophyllum atratum J.J.Sm. is described.... i find that collecting bulbos is great fun because there are lots of surprises!!!!
