Psydrax merrillii (Rubiaceae), a new combination for a Polynesian tree species
MOULY, A. (2024). Psydrax merrillii (Rubiaceae), a new combination for a Polynesian tree species. Candollea 79: 295–298. In English, English abstract. Canthium merrillii (Setch.) Christoph. is a tree restricted to the Polynesian archipelagos of Samoa, Tonga, and Wallis and Futuna. The paleotropical genus Psydrax Gaertn., which belongs to the tribe Vanguerieae of the family Rubiaceae, comprises unarmed shrubs bearing stamens with anthers reflexed on the filaments, whereas the species of the genus Canthium Lam. are characterized by being spinescent shrubs. Canthium merrillii (Setch.) Christoph. is therefore transferred to Psydrax based on the absence of spines. A description and an illustration of the species are provided.
