ad 5 cm longis ; bracteis numerosis, imbricatis, in siccitate viridis, 
ovatis ad ovato-ellipticis, 1 ad 1.5 cm longis, membranaceis, 
acutis ad obtusis, margine perspicue ciliatis, bracteolis nullis; 
floribus circiter 13 mm longis, calycis lobis linearis, tenuiter

An erect, sparingly branched herb attaining a height of 50 
cm, branched only in the upper part, the stems terete below, 
about 2 mm in diameter, dull-greenish, densely covered with 
short cystoliths, the branches sulcate or 4-angled, appressed- 
strigose. Leaves of each pair subequal, lanceolate, ehartaceous, 
green on both surfaces, shining and brittle when dry, 6 to 9 cm 
long, 1 to 2 cm wide, margins somewhat undulate, base abruptly 
rounded or obtuse, gradually narrowed upward to the slender 
but obtusely acuminate apex, the upper surface with numerous 
cystoliths distinctly visible to the naked eye, these wanting on 
the lower surface but the midrib and lateral nerves here ap- 
pressed-strigose ; lateral nerves about 10 on each side of the 
midrib, distant, distinct, prominently anastomosing; petioles 2 to 
8 mm long. Spikes 3 to 5, peduncled, 2.5 to 5 mm long. Bracts 
numerous, imbricate, foliaceous, green when dry, ovate to elliptic- 
ovate, 10 to 15 mm long, 6 to 9 mm wide, shortly stalked, base 
rounded to subacute, apex acute to obtuse, the margins prom- 
inently ciliate with long white hairs ; bracteoles none. Flowers 
white, about 13 mm long. Calyx-lobes free nearly to the base, 
linear, 8 to 9 mm long, about 1 mm wide, narrowed upward to 
the slenderly acuminate apex, prominently ciliate, the tip with 
about three, long, slender, white hairs. Capsules 8 mm long 
and 2 mm in diameter, slightly narrowed below, sparingly pub- 
escent in the upper part.

A species manifestly belonging in the group with Hemigraphis cuming - 
iana F.-Vill. and H. strigosa F.-Vill., but it is readily distinguished by its 
vegetative characters.
