The genus Amblovenatum J.P. Roux is a small genus in the Thelypteridaceae. Previously, the genus Amblovenatum was named Amphineuron (Holttum, 1971). In 2007, David Middleton argued for the homonyms between the genus Ampineuron (Thelypteridaceae) and the genus Amphineurion (Apocynaceae). By 2009, the name Amblovenatum was used by J.P. Roux to replac...
