Abstract
Mapouria Aubl. is a synonym of Psychotria L. In Madagascar and the Comoros there are 67 species of Mapouria that fall within the circumscription of Psychotria and correspondingly 64 species (67 taxa) require transfer to Psychotria. Thirty-seven new combinations and 30 new names are proposed; five lectotypes are designated.
Highlights
Mapouria Aubl. was described by Aublet (1775a), based on M. guianensis Aubl. collected from French Guiana
The plate is figured in vol 3 of Aublet’s ‘Histoire des Plantes de la Guiane Françoise ‘(1775b: pl. 67). In his summary on the identity of the genera Mapouria and Grumilea Gaertn., Bremekamp (1961: 319) stated that Mapouria should be applied to members of the tribe Psychotrieae that possess deciduous stipules, heterostylous flowers, pyrenes lacking a longitudinal intrusion on the commissural surface, and endosperm that is either ruminate on the adaxial surface only or extends over the whole surface
Bremekamp asserted that Mapouria, which was formerly used only for New World Psychotrieae, should be used for species that were previously included in Grumilea, and that Mapouria need not be given up in favour of Psychotria
