Type location:
Notes: 1 - Herbarium specimens without flowers can be distinguished in most cases from Bulbophyllum maximum because of the almost papery white peduncle scales.
2 - The specimen Greenway 6184 from ZAM. has an exceptionally wide rhachis of 1.3 cm wide.
3 - The specimens Greenway 6184 and Angus 459, both from ZAM., partly or entirely lack the concave top part of the anther.
