Bulbophyllum depressum

Bulbophyllum depressum is a small creeping epiphytic orchid described by King and Pantling from the eastern Himalaya and recorded widely across tropical Asia, from Hainan to Borneo and Java, with synonyms including B. acutum, B. hastatum and B. sundaicum. Herbarium labels from Sabah place it in montane and montane kerangas forest, often at about 1,300 to 2,000 m. Grow it mounted, warm-intermediate, in shaded humid conditions with daily watering.

Where it grows wild

An epiphyte of humid forest. Specimen labels from Sabah (Kinabalu Park, Long Pasia) describe montane forest and montane kerangas (heath) forest; other records come from Jianfengling on Hainan and Gunung Arjuno in East Java. Small creeping Bulbophyllum of this kind usually grow on mossy branches and trunks in shaded to dappled positions.

GBIF records span lowland to about 2,000 m, with many Bornean specimens between about 1,300 and 2,000 m. Plants from these heights prefer intermediate rather than hot conditions.
