Dendrobium crumenatum, commonly called Pigeon Orchid, is a member of the family Orchidaceae. It has 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 cmand 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 only lasts for a day.[2] 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. Dendrobium crumenatum is one of the most wide spread species of orchids in Asia, being found as far west as India, north in Taiwan to the Philippines and down to Sulawesi.[3] It grows in every locality from full sun to deep shade.
