Hi, I have recently gotten a nice Bulbophyllum nymphopolitanum and i also managed to take pictures of some other bulbophyllum within the same section. I think some of the species lookes very similar to each other.
Bulbophyllum nymphopolitanum
Bulbophyllum mearnsii
Bulbophyllum levanae ?
There are so much more form this section, same section as echinolabium too, i think.
