17,5 Merrill: Studies on Philippine Rubiaceae, IV 457 
An erect shrub, glabrous except in minutely puberulent in- 
florescences, the indumentum obscure, usually castaneous. 
Leaves oblong to oblong-obovate, membranaceous to chartaceous, 
15 to 20 cm long, usually 5 to 8 cm wide, or in the extreme form 
10 cm wide, brownish or somewhat olivaceous when dry, base 
acute or slightly decurrent-acuminate, apex slightly obtuse-acu- 
minate; lateral nerves 12 to 14 on each side of the midrib, rather 
distant, somewhat curved, prominent on the lower surface, anas- 
tomosing, the primary reticulations rather distinct and some- 
what lax; petioles 2 to 3 cm long; stipules deciduous. Panicles 
terminal, 3 to 3.5 cm long, about 5 cm wide, branched from the 
base or shortly peduncled, the branches verticillate, spreading, 
the lower ones 2 to 2.5 cm long, each branch usually dichoto- 
mous or trichotomous above, the ultimate branchlets usually 
bearing about three white flowers, their pedicels 1 to 2 mm long. 
Calyx about 2 mm long and wide, obscurely 4-toothed, corolla- 
tube 3 mm long, the lobes oblong-ovate, reflexed, 2 mm long, 
throat bearded. Styles slender, 4 mm long. Fruits obovoid, 
not sulcate, glabrous, about 7 mm long, brown or black when 
dry. Seeds plano-convex, not rigid, the albumen not ruminate. 
PANAY, Capiz Province, Jamindan, Bur. Sci. 31198 (type), 
31042 Ramos & Edaio, April and May, 1918, in damp forests 
along small streams. No. 31835 of the same collection unques- 
tionably represents the same species, this being the form with 
leaves about 10 cm in width. 
The alliances of this species are not entirely clear. It is suf- 
ficiently well characterized by its short, minutely puberulent in- 
florescences, the plants otherwise glabrous, associated with its 
obovoid fruits which are not ridged, and its seeds which are not 
at all ruminate.
