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 4 mm 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) , 

 336J^7 Ramos & Edano, December, 1918. In thickets and in 

 recent clearings at low altitudes. Bur. Sci. 33A77 Ramos & 

 Edano 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.
