Bulbophyllum scabratum

Rough bulb-leaf orchid

A miniature epiphytic orchid from the Himalaya to southern China, Taiwan and northern Indochina. It forms crowded clumps of small conical pseudobulbs with single leaves and bears umbels of small pale yellow flowers in spring. It grows on tree trunks in shaded ravines and along streams, so it likes intermediate to cool conditions, humid air and a drier winter.
