acuminate, the base acute, margins slightly recurved, coriaceous, 
5 to 8 cm long, 1.5 to 3 em wide, when dry shining on both 
surfaces, greenish or brownish, or more often the upper surface 
greenish and the lower brownish; lateral nerves about 15 on each 
side of the midrib, slender, not prominent, anastomosing, the 
reticulations lax, obscure; petioles 5 to 10 mm long; stipules 
lanceolate, acuminate, about 1 cm long, early deciduous. In- 
florescence terminal, about 4 cm long, with two primary branches 
from the base, slender, few-flowered, paniculate, the flowers 
disposed in threes on the ends of the ultimate branchlets, their 
pedicels about 2mm long. Calyx cup-shaped, 1.5 long and wide, 
truncate or obscurely denticulate. Corolla white, the tube cy- 
lindric, 4 mm long, villous inside, the lobes 4 or 5, oblong, obtuse, 
3mm long. Anthers 4 or 5, narrowly oblong, 1.5 mm long.

A species probably as closely allied to Psychotria loheri Elm. as to any 
other form, but distinguished by its much more numerous lateral nerves and 
longer inflorescence.
