182 DR. O. STAPF ON THE FLORA OF MOUNT KINABALU. 
Allied to Psychotria erratica, Hook. fil., and to P. viridiflora, Reinw., but differing from 
the former in the generally narrower leaves, the looser inflorescences, and the pedicelled 
flowers with more exserted anthers and a much less villous throat, and from the latter, 
which it approaches indeed very closely, in the narrower leaves, but chiefly in the 
larger, more oblong berries, with a much thinner endocarp.

At 8000 feet (Haviland, 1116). 
Nearest allied to P. polycarpa, Hook. fil., but one of the best marked species, distin- 
guished by the crowded, small, and glossy leaves, and the short inflorescences.
