Bulbophyllum gravidum

A small epiphytic Bulbophyllum from the montane forests of Mount Cameroon and Bioko, described by Lindley in 1862. Vermeulen later treated it as a variety of the widespread African B. cochleatum. It grows at about 1,500 m in cool, very wet mountain forest and is listed as Vulnerable because that forest is being cleared. Grow it as an intermediate, humid, bright-shade orchid on a mount.

Where it grows wild

It grows as an epiphyte on trees in montane forest. Records under the broader B. cochleatum concept also mention humid primary forest, light woodland and trees in waterfall spray zones, so it favours bright, humid positions on trunks and branches.

About 1,500 m on Mount Cameroon and Pico Basilé (Bioko). GBIF records assigned to the name range up to about 1,830 m.
