Corymborkis

Corymborkis, commonly known as cinnamon orchids, or 管花兰属 (guan hua lan shu) is a genus of eight species of orchids in the family Orchidaceae. They are evergreen, terrestrial plants which grow in clumps and have thin roots, leafy stems, pleated leaves and widely-opening flowers with thin, spreading sepals and petals. They are widely distributed in the tropics.

==Description== Orchids in the genus Corymborkis are terrestrial, evergreen herbs which often grow in clumps and have short rhizomes and thin, wiry stems. One or more thin, unbranched stems arise from the same rhizome and have many papery, pleated, egg-shaped to elliptic leaves near their top half. A branching flowering stem develops from the upper leaf axils and carry crowded, widely-opening flowers. The flowers are greenish white and usually have thin, spreading sepals and petals which are similar to each other, with the petals slightly wider than the sepals. The labellum is about as long as the sepals, closely surrounds the column and has a tube-like base and two longitudinal ridges.
