The genus is distributed in China (Yunnan, Chihli).

Etymology: The source of the name is Greek a (not), keratos (horn) and Orchis (orchid), for the spurless lip of the type species.

The type species (genotype) is not designated (non designatus) in the description.

Similar and related genera include Habenaria Willdenow and Orchis Linnaeus.

Characteristics: Species in this genus are distinguished in having the lip shaped like the petals.  (imagery courtesy of )
