Dendrobium crumenatum, commonly called pigeon orchid, is a member of the family Orchidaceae. It is native to India, Indochina, Taiwan, Philippines, Malaysia, Indonesia, New Guinea, and Christmas Island. It is reportedly naturalized in Fiji, Hawaii, the West Indies and the Seychelles.[2][3][4] It grows in many localities from full sun to deep shade.

Dendrobium crumenatum produces upright, sympodial, pseudobulbs that are swollen at the first 3 or 4 bottom nodes. The middle portion carries the leaves of 7 cm long and 2 cm wide that are very leathery. Top portion of the pseudobulbs carry the flowers of about 2.5 cm and of pure white, with yellow markings on the labellum. The bloom cycle is triggered 9 days after a sudden drop in temperature (at least 5.5 °C or 10 °F), usually as a result of rain, although the same effect can be artificially created. Dendrobium crumenatum flowers are fragrant, but the scent lasts only for one day.[5] Olof Swartz named this plant in 1799 in Schrader's Journal fur die Botanik. The specific name refers to the purse-shape spur of the flower.
