The correct name for Matelea chacoensis Goyder (Apocynaceae: Asclepiadoideae) [PDF]
Kew Bulletin, 2016 Matelea chacoensis Goyder was proposed as a replacement name for the illegitimate Gonolobus hirtus Griseb., a later homonym of G. hirtus (L.) R. Br. ex Schultes. However, the synonym Pseudibatia hirta Malme, which may be considered a legitimate replacement name, makes an earlier epithet available.

A New Combination in Matelea (Asclepiadaceae) and Lectotypification of M. Parvifolia
Brittonia, 1991Vegetative similarities as well as a syntype specimen with discordant elements have evidently misled botanists to equateLachnostoma hastatulum withGonolobus parvifolius. Both species are considered representatives of a broadly interpreted genusMatelea, subgenusChthamalia. A new combination,M. hastatula, is proposed, andG. parvifolius is lectotypified.
