Cleisocentron is a genus of flowering plants from the orchid family, Orchidaceae.[4] It has a disjunct distribution, known from the Himalayas, Vietnam, China and Borneo.
Description
[edit | edit source]_-_The_Orchids_of_the_Sikkim-Himalaya_pl_306_(1898).jpg)
The species of this genus are tropical epiphytes with a pendent or erect habit. The leaves may be terete or broad. Both types of leaves may occur on the same specimen, as some species exhibit leaf polymorphy.[5] Three species have blue flowers,[6] but other colours, such as pink and white also occur.
Cytology
[edit | edit source]The diploid chromosome count is 2n = 38.[7]
Etymology
[edit | edit source]The generic name is derived from the Greek kleistos meaning closed,[8] as well as kentron meaning spur.[6][8] The name relates to the morphology of the spurred labellum.[5]
Ecology
[edit | edit source]Pollination
[edit | edit source]There have been reports of pollination or visitation by ants, which was observed during field expeditions in Borneo.[9][10] Alternatively, there have been speculations, that the nectariferous flowers are pollinated by butterflies.[6]
Taxonomy
[edit | edit source]It was published by Paul Johannes Brühl in 1926[1][11] with Cleisocentron trichromum (Rchb. f.) Brühl as the type species.[1]

[edit | edit source]Eight species are currently recognized:[12]
- Cleisocentron abasii Cavestro - Sabah
- Cleisocentron gokusingii J.J.Wood & A.L.Lamb - Sabah
- Cleisocentron kinabaluense Metusala & J.J.Wood - Sabah
- Cleisocentron klossii (Ridl.) Garay - Vietnam
- Cleisocentron malipoense (Z.J.Liu & L.J.Chen) R.Rice - Malipo, Yunnan, China [13]
- Cleisocentron merrillianum (Ames) Christenson - Sabah

- Cleisocentron pallens (Cathcart ex Lindl.) N.Pearce & P.J.Cribb - eastern Himalayas (Sikkim, Bhutan, Assam, India)
Formerly included species
[edit | edit source]- Cleisocentron collettianum (King & Pantl.) Garay is now considered a synonym of Robiquetia pachyphylla (Rchb.f.) Garay.[15]
Horticulture
[edit | edit source]Cleisocentron is rarely found in cultivation.[8][5] However, they are easy to cultivate.[8] Numerous intergeneric hybrids with Cleisocentron have been described.[11]
