17,6 Merrill: Studies on Philippine Rubiaceae, IV 447 
An erect shrub, the branchlets, petioles, inflorescences, and the 
lower surface of the leaves on the midribs and nerves casta- 
neous-pubescent with short, rather harsh hairs. Branches terete, 
wrinkled, glabrous, grayish or brownish, about 4 mm in diameter. 
Leaves subcoriaceous, oblong-elliptic to oblong-obovate, 15 to 18 
cm long, 6 to 9.5 cm wide, the upper surface pale, shining, the 
lower brownish or reddish-brown, the apex blunt-acuminate, 
base somewhat narrowed (3 to 4 cm) and abruptly and conspicu- 
ously cordate, the sinus narrow, the lobes rounded; lateral 
nerves about 16 on each side of the midrib, very prom- 
inent on the lower surface, somewhat curved, distinctly anas- 
tomosing, the primary reticulations distinct; petioles densely 
castaneous-pubescent, 1.5 to 3 cm long; stipules deciduous, not 
seen. Inflorescences terminal, castaneous-pubescent, 3-branched 
from the base, the branches about 3 cm long, each bearing at 
its apex a subcapitate infructescence 2 to 2.5 cm in diameter. 
Fruits 10 to 15 on each branch, the immature ones obovoid, 
about 8 mm long, smooth, not at all sulcate, dark-brown when 
dry, glabrous, their pedicels 3 to 5 mm long, pubescent.

The alliance of this species is manifestly with Psychotria 
alvarezii Merr., from which it differs in its broader, differently 
shaped leaves and, especially, in its fruits, which are not at all 
longitudinally sulcate.
