Abstract

Abstract— Conchocarpus is the largest genus of Galipeinae (tribe Galipeeae), which is the most diverse group of Neotropical Rutaceae, with ca. 50 species. Recent phylogenetic analyses support a recircumscription of Conchocarpus to accommodate the species of Almeidea, a taxon from the Brazilian Atlantic Rainforest and Bolivia whose synapomorphy is the possession of pantocolporate pollen grains. Four species are recognized here: C. albiflorus, C. coeruleus, C. hendrixii, and C. ruber. A taxonomic revision of this group of four species of Conchocarpus is provided, with updates of their nomenclature, morphology, circumscription, geographic distribution, and preliminary conservation status, as well as a key to the species and illustrations. Conchocarpus limae and C. lilacinus are consigned to the synonymy of C. ruber.
