Calanthe Monophylla

''Calanthe'', commonly known as Christmas orchids, is a genus of about 220 species of orchids in the family Orchidaceae. They are evergreen or deciduous terrestrial plants with thick roots, small oval pseudobulbs, large corrugated leaves and upright, sometimes arching flowering stems. The sepals and petals are narrow and a similar size to each other and the labellum usually has spreading lobes.

Description

Orchids in the genus ''Calanthe'' are terrestrial with small, crowded pseudobulbs with thick roots and a few corrugated or wrinkled leaves with the base tapering to a petiole-like stalk. Some species are evergreen while others are deciduous. The flowers are delicate but showy, white, pink, yellow or orange and crowded near the end of an erect, sometimes arching flowering stem. The sepals and petals are relatively narrow, similar in size and spread widely. The labellum has three or four spreading lobes and in most species there is a spur at the base. Unlike similar orchids, the labellum of ''Calanthe'' orchids is fused to the column.

Taxonomy and naming

The genus ''Calanthe'' was first formally described in 1821 by Robert Brown and his manuscript was published in '' The Botanical Register''. The name ''Calanthe'' is derived from the Ancient Greek words ''kallos'' meaning "beauty" and ''anthos'' meaning "flower".

Distribution and habitat

''Calanthe'' species are found in all tropical areas, but mostly concentrated in Southeast Asia. Some species also range into subtropical and tropical lands such as China, India, Madagascar, Australia, Mexico, Central America, the West Indies and various islands of the Pacific and Indian Oceans.
