Dendrobium crumenatum, commonly called pigeon orchid,[1] or 木石斛 (mu shi hu)[2] is an epiphytic orchid in the family Orchidaceae and is native to Asia, Southeast Asia, New Guinea and Christmas Island. It has two rows of leaves along its pseudobulb and relatively large but short-lived, strongly scented white flowers. It usually grows in exposed positions in lowland rainforest and coastal scrub.
Description
Dendrobium crumenatum produces upright, sympodial, pseudobulbs Template:Convert long and Template:Convert wide that are swollen at the first three or four lower nodes. The middle portion of the pseudobulb has two rows of leathery, oblong to egg-shaped leaves Template:Convert long and Template:Convert wide. Top portion of the pseudobulb bears pure white flowers Template:Convert long and wide. The dorsal sepal and petals are Template:Convert long and Template:Convert wide, the lateral sepals slightly longer and wider. The labellum is Template:Convert long and Template:Convert wide with three lobes. The side lobes are erect and the middle lobe is rounded with five yellow ridges. Flowering is sporadic but is triggered nine days after a sudden drop in temperature of at least 5.5 °C, usually as a result of rain, although the same effect can be artificially created. The flowers are fragrant, but the scent lasts only for one day.[1][2][3] Joseph Arditti describes the flowering as "gregarious". All the flower buds in a geographic area will bloom on the same day, for exactly one day, none early, none late.[4]
Taxonomy and naming
Dendrobium crumenatum was first formally described in 1799 by Olof Swartz and the description was published in Heinrich Schrader's Journal für die Botanik.[5][6] The specific epithet (crumenatum) is derived from the Latin word crumena meaning "leather moneybag".[7]
Distribution and habitat
The pigeon orchid usually grows in exposed locations, often in lowland rainforest or coastal scrub. It is found in India, Indochina, Taiwan, the Philippines, Singapore, Malaysia, Indonesia, New Guinea, and Christmas Island. It is reportedly naturalized in Fiji, Hawaii, the West Indies and the Seychelles.[8][2][9]
