] Suffrutescent or woody, erect, much branched, 0.0 to 1.4 m. high. 
Branches slender or somewhat tliickencd, brown, pubescent, becoming 
glabrous. Leaves membrauous, oblong-ovate to ovate-lanceolate, 3 to 
7 cm. long, 1 to 2.5 cm. wide, the apex acute or sharp-acuiuinatCj the 
base acute, both surfaces pubescent witli weak scattered hairs, dull; 
nerves 3 to 5 on each side of tlic midrib, ascending, distinct; petioles 
^ pubescent, 0.5 to 1.5 em. long; sti2:>ules pubescent, laciniate, the lacinise 
setiform, pubescent, 4 to 7 mm. long. Inflorescence axillary, the pedun- 
cles pubescent, 2 to 4 cm. long, slender, each bearing a single terminal 
head of sessile flowers, 1 cm. in diameter or less, the bracts foliaccous, 
i forming an involucre, tlie bracts and flowers more or less hispid-pubescent, 
the pedicels 1 mm. long or less. Calyx tube about 1 mm. long, the lobes 
4, linear or lini'ai''lanceolatc, 2.5 mm. long, the mature capsule 2 to 
2.5 mm. long. 
■djK In forests at 1,800 m. alt. (N"o. 5720); also collected by Merritt at 1,000 m. 
alt. (Nos. 4417, 4430). 
A species evidently closely related to Hedyotis macrostcgia Stapf, from Mount 
Kinabalu, North Borneo, differing from that species in its pubescent, fewer nerved 
leaves, much shorter stipules, and other characters. It is distingxiinhod from all 
other Philippine species of the genus by its long jicduncled capitate solitary 
axillary inflorescence.
