Bulbophyllum pecten-veneris

Golden comb orchid

A small creeping Cirrhopetalum-type Bulbophyllum of subtropical East Asia, with umbels of yellow flowers; it was described by Gagnepain in 1931 as Cirrhopetalum pectenveneris. It grows on tree trunks and rocks in evergreen broadleaf forest from eastern China and Taiwan to northern Vietnam, where summers are hot and wet and winters cool and drier. Mount it and give it bright shade, frequent summer watering and a cooler, slightly drier winter.
