Bulbophyllum sphaericum

A tiny creeping Bulbophyllum from Sichuan and south-west Yunnan, with globose pseudobulbs about 7–8 mm across spaced 1 cm apart, each with a single thick leaf about 1 cm long that is purplish red beneath. Umbels of four or five purplish red flowers with long, joined lateral sepals appear in autumn. It grows on tree trunks in evergreen broad-leaved forest; no elevations are published, so cultivation targets are estimates.
