Phalaenopsis cacharensis

An epiphytic orchid known from a single plant in the Cachar district of Assam, India, first described as Ornithochilus cacharensis in 2014 and later moved to Phalaenopsis. It has mid-green leaves about 20 cm long and long sprays of 30–70 small red-purple flowers. It is critically endangered and essentially unknown in cultivation, so these notes describe its habitat more than proven care.
