Bulbophyllum cruciatum

A small creeping epiphytic Bulbophyllum from the warm lowland forests of New Guinea and the Moluccas. It has clustered conical pseudobulbs, each with a single leaf, and produces single cross-shaped purple and white flowers on very short stems from the base of the pseudobulbs. Grow it warm, humid and evenly moist, mounted or in a shallow basket.

Where it grows wild

Epiphyte on trees in warm, wet primary forest; one collection notes steep primary forest about 25 m tall on ultrabasic soil with little undergrowth, and others come from rainforest and more open woodland.

Reported from about 5 to 1,100 m; the few GBIF records with elevations range from about 100 to 1,100 m.
