Cleisocentron is a genus of flowering plants from the orchid family, Orchidaceae.[3] It has a disjunct distribution, known from the Himalayas, Vietnam, China and Borneo.

Description

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.[4] Three species have blue flowers,[5] but other colours, such as pink and white also occur.

Etymology

The generic name is derived from the Greek kleistos meaning closed,[6] as well as kentron meaning spur.[5][6] The name relates to the morphology of the spurred labellum.[4]

Ecology

Pollination

There have been reports of pollination or visitation by ants, which was observed during field expeditions in Borneo.[7][8] Alternatively, there have been speculations, that the nectariferous flowers are pollinated by butterflies.[5]
