NOTE. — Trichoscypha arborea is rather difficult to distinguish from T. patens (Oliv.) Engl. , a common species in Lower Guinea. Both occur in Nigeria and western Cameroun. Apart from the difference in flower colour, the two species look in fact quite different, especially their leaves, although these differences are not so easy to circumscribe (see KEAY, 1958: 734). The distinction between these two taxa will be delt with when treating Trichoscypha from Lower Guinea.
