The plant has a short, stout, creeping stem carrying up to 12, curved, fleshy, deeply channeled, keeled, retuse apically leaves and blooms on an axillary pendant to 60 cm (24 in) long, racemose, densely flowered, cylindrical inflorescence that occurs in the winter and early spring. It is famous for its use as a hair-ornament worn by Assamese women during folk dance Bihu on the onset of spring.[2]

It can be found in Bhutan, Cambodia, China (Guizhou, Yunnan), India , Indonesia, Laos, Malaysia, Myanmar, Nepal, Philippines , Singapore, Sri Lanka, Thailand, and Vietnam.[3]
In India, the plant is most common in North-East, Orissa and Andhra Pradesh. In Andhra Pradesh, the plant is called by Telugu name Chintaranamu. Due to bio-piracy,[citation needed] the plant is on the verge of extinction in India. Rhychostylis retusa is recognized as the state flower of Arunachal Pradesh and Assam in India as well the Uva Province of Sri Lanka.

The plant requires regular watering and applications of fertilizer throughout the year,[2] although it will die if the leaves are wet frequently.[citation needed] It prefers indirect lighting. Flowering usually occurs in late spring.[4]
