hirsutis, lineari-lanceolatis, circiter 7 mm longis; corolla alba, 
_ 1.8 cm longa, extus leviter pubescens; filamentis longioribus 
perspicue villosis ; capsulis 11 mm longis, oblongis, cinereo-pubes- 
centibus. 
An erect, branched, somewhat hirsute herb, up to 60 cm high, 
the older stems glabrous, terete or somewhat 4-angled, the 
younger branches sparingly hirsute with short, usually ap- 
pressed hairs. Leaves in equal or subequal pairs, coriaceous, 
olivaceous, brittle when dry, elliptic to oblong, 6 to 11 cm long, 
2 to 4 cm wide, subequally narrowed to the acute base and the 
acute or somewhat acuminate apex, the upper surface glabrous, 
smooth, and with numerous, irregularly arranged cystoliths, 
the lower surface scabrid and more or less pubescent on the 
midrib and nerves, the margins irregularly crenate; lateral 
nerves 5 or 6 on each side of the midrib, rather prominent, 
anastomosing, the primary reticulations lax; petioles more or 
less pubescent, 1 to 2 cm long. Inflorescences terminal, usually 
consisting of 3 peduncled spikes from the tip of each branch, 
the peduncles up to 1.5 cm long, the spikes up to 5 cm in length. 
Bracts coriaceous, oblong to lanceolate, narrowed upward to 
the obtuse apex and below to the acute base, 12 to 14 mm long, 
4 to 5 mm wide, sparingly hirsute with stiff, short hairs on 
both surfaces. Calyx about 7 mm long, somewhat hirsute, the 
lobes linear-lanceolate, slender, acuminate, nearly free, the tips 
of the lobes supplied with 1 to 3 very slender hairs up to 2 mm 
in length. Corolla white, about 1.8 cm long, the tube glabrous 
in the lower, slender 6 mm, then gradually widened and spar- 
ingly pubescent, the lobes broadly ovate, 3 to 4mm long. Longer 
filaments 2 mm in length, densely villous on one side, the shorter 
ones very sparingly villous; anthers 2 mm long. Ovary oblong, 
2 to 5 mm long, densely pubescent; style somewhat villous. Cap- 
sules about 11 mm long, cinereous-pubescent, oblong, somewhat 
acuminate; seeds ovoid, 1.3 mm long, minutely pubescent. 
Luzon, Camarines Province, Paracale, Bur. Sci. 33974 (type), 
33647 Ramos & Edaio, December, 1918. In thickets and in 
recent clearings at low altitudes. Bur. Sci. 33477 Ramos & 
Edafio from the same locality differs in its relatively somewhat 
broader, longer-petioled leaves, but probably represents the same 
species. 
A species in the general alliance with Hemigraphis cumingiana 
F.-Vill., from which it is distinguished among other characters by 
its much thicker leaves which are scabrid on the lower surface.
