Bulbophyllum trigonopus

A small creeping Cirrhopetalum-type Bulbophyllum of lowland and hill forests in Thailand, the Malay Peninsula, Singapore, Borneo and Sumatra, with small umbels of flowers held on a slender stalk. It is widely known under its synonyms Bulbophyllum pulchellum and Cirrhopetalum concinnum. Treat it as a warm-growing, constantly humid epiphyte without a dry rest.

Where it grows wild

An epiphyte on branches and trunks in humid tropical forest, creeping along the bark with pseudobulbs spaced along the rhizome. Detailed habitat notes for this species were not found in the sources consulted; this is inferred from its range and from related Cirrhopetalum-type species.

Only one GBIF record carries an elevation (750 m). Its range is mainly lowland to hill forest, likely below about 1000 m, but this is not confirmed by a species-specific source.
