Taxonomy

The genus was named by Joseph Gaertner in 1788 in his book, De Fructibus et Seminibus Plantarum . [1] Psydrax is a Greek word meaning a blister or bump. Gaertner may have chosen this name to refer to the warty fruit or the pimply seeds of some species. [2] The name was hardly ever used after Gaertner proposed it because most authors placed these species in Canthium . Psydrax was reinstated in 1985 and 37 African species were transferred to it from Canthium . [3] The monospecific genus Mesoptera was also sunk into Psydrax. [4] Psydrax was shown to be monophyletic in a molecular phylogenetic study. [5] It is closely related to Afrocanthium , Cyclophyllum and Keetia , genera that have been segregated from Canthium .
