Bulbophyllum oblongum

Bulbophyllum oblongum, first described as Trias oblonga, is a small, clustered epiphytic orchid from north-east India, Bangladesh, Myanmar, Thailand and the Andaman Islands. It grows on forest trees from the lowlands to about 1,200 m in a monsoon climate, so it wants warm-intermediate conditions, humid summers and a somewhat drier, cooler winter. Field information is very thin, and most records are old herbarium sheets.

Where it grows wild

An epiphyte on forest trees. Herbarium labels give little more detail than that, but the range, from Andaman lowland forest and the Rangoon and Moulmein area to the Garo Hills, is monsoon forest with a pronounced dry season.

Records run from near sea level (Andaman Islands, Rangoon, Moulmein) to about 610 to 1,200 m in the Garo Hills and northern Thailand.
