Acianthera is a genus of orchids native to the tropical parts of the Western Hemisphere,[1] especially Brazil.[2] It was first described in 1842[3] but was not widely recognized until recently. Most of the species were formerly placed under Pleurothallis subgenus Acianthera. This splitting is a result of recent DNA sequencing.
As of October 2022, Plants of the World Online accepted about 300 species within Acianthera:[4]
