Microchilus is a neotropical genus of 78 species belonging to the orchid family (Orchidaceae).

This genus was separated in 2002 by P. Ormerod from the genus Erythrodes

Erythrodes

Erythrodes is a genus of flowering plants from the orchid family, Orchidaceae.- References :*Pridgeon, A.M., Cribb, P.J., Chase, M.A. & Rasmussen, F. eds. . Genera Orchidacearum 1. Oxford Univ. Press....

s. str.. It corresponds to its New World species. The two genera were distinguished by the different characters of the column

Column

A column or pillar in architecture and structural engineering is a vertical structural element that transmits, through compression, the weight of the structure above to other structural elements below. For the purpose of wind or earthquake engineering, columns may be designed to resist lateral forces...

 and pollinia

Pollinium

Pollinium, or plural pollinia, is a coherent mass of pollen grains in a plant.They are the product of only one anther, but are transferred, during pollination, as a single unit. This is regularly seen in plants such as orchids and many species of milkweeds .Most orchids have waxy pollinia...

. One needs to dissect the flowers to see the difference at generic level with Erythrodes.

In 2005, another 32 new species were added to this genus by Ormerod (see : Reference).

The horticultural abbreviation for this genus is Mcr.
