This is a beautiful species with elegant white and wine red flowers, | which   are shown on a pendulous inflorescence from a plant which has also graceful foliage.

John Day of Tottenham, London, was the first person to flower this species in Europe, in 1869, after importing it from Assam India in 1865.

It is a medium sized epiphyte, although Valmayor states it is a terrestrial in the Philippines. It has small 40 x 25 mm pseudobulbs. The 5 to 8 400 to 950 mm long leaves are somewhat thickened and coriaceous, dark green with a mid-vein below. The scape is 180 to 300 mm long, somewhat erect to horizontal, bearing 5 to 15 flowers, sometimes up to 20. The flowers are 40 to 50 mm across, usually not scented. The petals and sepals are white or cream with a central maroon stripe that does not reach the apex, or occasionally suffused wine-red with a deeper central stripe. The lip is white, strongly marked with maroon, with an orange or yellow spot at the base.

This species is distributed from North India, China, Taiwan, Ryukyus, Japan, Philippines, Thailand, Cambodia, West Malaysia, Sumatra, and Sabah, growing 300 to 1800 metres above sea level. It prefers a brght position in evergreen forest, in hollows in trees and on fallen, rotting logs, often in damp, and rotting wood. It flowers in late summer to late autumn, and sporadically throughout the year in tropical latitudes. Out of season flowering is not uncommon under cultivation.
