NOTES. — It was with some difficulty and only after other species had been excluded that Trichoscypha dinklagei, of which all the type material was lost, could be identified as representing T. bijuga. The short pedicel, the short stamens, and the glabrous disc, as mentioned in the original description, point to this species. Trichoscypha bijuga is a common species in the region around Kribi where DINKLAGE collected the type of T. dinklagei. More than 20 out of a total of 55 collections of this species examined from Cameroun are from this area, one of which from near Kribi is here designated as the neotype.
