Pleurothallis is a genus of orchids commonly called bonnet orchids. This was a huge genus, which used to contain more than 1,200 species - the second largest in the Orchidaceae after Bulbophyllum.
The genus name is derived from the Greek word pleurothallos, meaning "riblike branches". This refers to the rib-like stems of many species.
