longis; cymis axillaribus, solitariis, longe pedunculatis, 8 ad 12 
cm longis, ramis paucis, circiter 2 cm longis, fructibus breviter 
pedicellatis, circiter 3 mm longis. 
An erect, glabrous shrub, the branches and branchlets acutely 
4-angled. Leaves chartaceous, oblong-ovate, subolivaceous when 
dry, shining, the lower surface paler than the upper, 11 to 15 
cm long, 2.5 to 5.5 cm wide, subequally narrowed to the slightly 
acuminate base and apex, or the latter merely acute, smooth; 
lateral nerves 5 to 7 on each side of the midrib, distinct, ascend- 
ing, scarcely projecting, not at all impressed on the upper surface, 
the reticulations obsolete or nearly so; petioles 1.5 to 3 cm long; 
stipules oblong-ovate, acuminate, laciniate, about 6 mm long. 
Cymes axillary, solitary, long-peduncled, 8 to 12 cm long, the 
peduncular parts 6 to 8 cm in length; primary branches few, 
verticillately arranged, about 2 cm long, the capsules somewhat 
crowded at the ends of the branches, their pedicels 2 to 3 mm 
long; bracts oblong, subacute, about 6 mm long. Capsules 
obovoid, about 3 mm long, the persistent calyx-teeth ovate, sub- 
acute, about 3 mm in length.

This species is well characterized by its acutely angled branches 
and branchlets, its relatively large leaves, and its long-peduncled 
axillary inflorescences. It somewhat resembles Hedyotis fruti- 
culosa Volkens, of the Caroline Islands and, among the Philip- 
pine species, is probably closest to Hedyotis phanerophlebia 
Merr. ; from both of these it differs radically in its vegetative 
and inflorescent characters.
