Bulbophyllum cruentum

Blood-red Bulbophyllum

A small epiphytic Bulbophyllum from the lower montane forests of New Guinea, with 3 cm pseudobulbs, a single leaf, and one or two very fleshy, blood-red flowers held tight against the base of the pseudobulb. The few herbarium specimens come from the Baliem Valley in the central highlands, so it is best grown intermediate to cool with steady humidity and no dry rest.

Where it grows wild

Epiphyte in lower montane forest; one Baliem Valley specimen was collected on deforested slopes. Grows in dappled shade with good air movement.

No specimens carry an elevation; the Baliem Valley floor lies at about 1,600 m, consistent with a lower montane species.
