Paphiopedilum hirsutissimum

A large, hairy-flowered slipper orchid found from Assam through Myanmar, northern Thailand, Laos and Vietnam to southern China. It grows in humus pockets on limestone at mid elevations, where summers are warm and wet and winters are cool and dry. That cool, drier winter is what triggers flowering in spring.
