Bulbophyllum callichroma

A New Guinea Bulbophyllum of section Macrouris with ovoid pseudobulbs spaced along a creeping rhizome and long pendulous inflorescences of 4–14 flowers, the sepals yellow to purple, petals white and lip purple. It grows as an epiphyte in lower montane forest at about 600–1700 m, so it is an intermediate grower that wants humid, moving air all year.
