This orchid is native to an area extending from Vanuatu to the Society Islands. In Fiji it is found only in Viti Levu and Ovalau growing in areas of strong light from sea level to 900 meters. The plants, growing as epiphytes on trees, build up large clumps of thin canes which can be 1.5 meters long. The flowers, usually in pairs, are about 3cm across with thin and spidery, pale creamy/yellow petals and sepals. They only last one day. It is possible that flowering may be triggered by a sudden drop in temperature. The orchid can be seen in the old rubber trees at Wainadoi and on raintrees in Suva.
