A pendulous medium sized, hot growing epiphyte found in Papua and New Guinea, the Solomon Islands, Fiji, Samoa and Vanuatu in lowland rainforest at altitudes of 100 to 500 meters with a very short stem carrying 4, ensiform, acute leaves and blooms on an initially horizontal and then pendulous, 20" [50 cm] long, terminal, many flowered inflorescence arising from between the central leaves that has many [several hundred] small flowers occuring in the spring and summer in nature.

This orchid is best mounted to accomodate the pendant inflorescence that has many flowers. Good ventilation, high humidity, bright shade and a tree fern mount with daily waterings will ensure happy growing.
