Plants 40-380 mm. Leaves 1-3, alternate, narrowly ovate, 3-43 × 3-31 mm. Flowers 1-5(-10), white or pink; median sepal lanceolate, 5-14 × 0.7-2.2 mm, hood shallow, lateral sepals ovatelanceolate, 5-15 × 1.5-8 mm, joined in basal quarter or half; petals ovate-lanceolate, 5.5-14 × 2-5 mm; lip blade rotund, stalked, with hairy crest, appendage of two papillose spreading or ascending processes.

DISTRIBUTION AND PHENOLOGY. — Widespread but localised in Asia, recorded in India, Sri Lanka, Thailand, Indonesia, Hong Kong, Taiwan, southern Japan, the Caroline Island Pulau, the Philippines and Papua New Guinea; growing in forest as well as in grassy places, at altitudes of up to 1600 m; the flowering time is rather diverse depending on the climate of the region. The 10 originally described Asian Disperis species were recently shown to be conspecific ( KURZWEIL 2005).
