NOTES. — OLIVER based this species on Mann 1749 (Ƌ fl.) and Mann 1830 (young fruits), both collected at 1°N latitude, River Muni, in Central Africa. Although OLIVER did not cite MANN’ s material by number, it is clear that he had two collections at hand for his description, a male and a female plant. Both specimens have been located at K and both bear the name Trichoschypha lucens in the same handwriting. They are not conspecific however, and ENGLER (1881) based his Trichoscypha oliveri on Mann 1830. Two years later, in the monograph of the Anacardiaceae, ENGLER (1883) treated both T. lucens and T. olivieri . Here, he explicitly restricted the former name to Mann 1749, which lectotypified T. lucens by this specimen.

Trichoscypha oba was based on three syntypes, Martineau 297 and 317 from the Banco Forest near Abidjan, and Jolly 154 from Dabou. Martineau 297 has been chosen lectotype because it is the only collection with male flowers and the only one that is duplicated in another herbarium .

Trichoscypha lucens is the most common and the most variable member of the genus in Upper Guinea (see also note under T. smythei ). This variation especially concerns the leaves in many of their aspects. The habit of T. lucens , however, has always been quoted as a shrub or small tree, never a liana. The lectotype, Mann 1749, however, is described as a “climbing plant of 30 feet ”.
