Description

Illustration of Cleisocentron pallens

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

Cytology

The diploid chromosome count is 2n = 38.

Etymology

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

Ecology

Pollination

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

Taxonomy

It was published by Paul Johannes Brühl in 1926 with Cleisocentron trichromum (Rchb. f.) Brühl as the type species.
