Pleurothallis is a genus of orchids commonly called bonnet orchids. The genus name is derived from the Greek word pleurothallos, meaning "riblike branches". This refers to the rib-like stems of many species. The genus is often abbreviated as "Pths" in horticultural trade.

This was a huge genus, which contained more than 1,200 species - the second largest in the Orchidaceae after Bulbophyllum. In 2004, it decreased by more than half when many species were moved into new genera.[2]
