Carapichea guianensis: the correct name for Psychotria carapichea (Rubiaceae), with a correction on the authority of P. carapichea, and a new combination in Carapichea. Brittonia 55: 88–89. 2003.—The correct name for Psychotria carapichea is Carapichea guianensis. Also, the authority of Psychotria carapichea was previously incorrectly cited, because of an oversight of the illegitimacy of Tapogomea carapichea Poir. The complex taxonomic history of this species is analyzed, and the authority of the binomial is correctly cited. In addition, P. ligularis, which was treated as closely related to C. guianensis in previous publications, is transferred to Carapichea and it is now known as Carapichea ligularis.
