Lectotypus (designated by WELSCH, 1998: 246): FRENCH POLYNESIA. Society Archipelago: Tahiti, Oruopo à Orofero , 2.VIII.1857, Nadeaud 345 ( P [ P02275121 ]!) .

Notes. – This species is endemic to the Society Archipelago ( WELSH, 1998). The names Psychotria cernua and P. lepiniana have sometimes been treated as two separate species (e.g., FOSBERG, in sched. in P) but these are not distinct nomenclaturally. The name P. cernua was an illegitimate later homonym when published, and the name Uragoga lepiniana was then published explicitly to replace it. Thus, U. lepinina and the later combination based on it, P. lepiniana , are both typified by the type of P. cernua . No specimen at P exactly matches the protologue locality of P. cernua , “à la base du Mont Mahufaa au fond de la vallée d’Orofero, et sur les étages inférieures de l’Orohena vers 800 et 1000 m ..... en fleurs et en fruit le 20 décembre 1857 ”. The collection Nadeaud 345 at P generally corresponds to this locality and has been regarded as the type of this name (FOSBERG, in sched. in P; WELSH, 1998). This specimen has both flowers and fruits on it, but the dates given in the protologue for flowering and fruiting differ from the date on its label. WELSH (1998) cited this single specimen as the type of this species, which constitutes an effective lectotypification.
