Abstract

Campyloneurum typically has simple and entire leaves; however, three of its species are 1-pinnate: C. decurrens, C. magnificum, and C. pentaphyllum. These three species form a clade that is sister to the rest of the genus. The 1-pinnate clade is here named as Campyloneurum subgen. Decurrentia. This paper provides a taxonomic revision of the three species, presenting a key to distinguish them, descriptions, distribution maps, and specimens examined. A lectotype is designated for C. decurrens var. latifolium, and a second-step lectotype for C. magnificum.
