thin and flaccid when dry, oblanceolate-acuminate,
acute, narrowed a long wa}- to the base, glabrous, 6 inches
long, 2 inches wide; nerves 10 to 11 pairs, slender; petiole i^
inch long. Stipules lanceolate-ovate, mucronate. Peduncles
terminate, green, flattened, 2 inches long; capitulum of 17
sessile flowers. Bracts several, ovate, rounded, truncate,
green, i to ^ inch long, one below the head on the peduncle

A very distinct plant in its size and in the thin leaves
and white flowers ; allied to C. cuneata, Korth.
81. PsYCHOTRiA SAKMENTOSA, BL, var. On the Padang
in woods, climbing. I take this to be a mountain form of
P. sarmentosa, reduced in all parts and with more coriaceous
leaves. I have somewhat similar forms, but less distinctly
condensed, from Mount Ophir and Matang in Borneo.
The species is common all over the Malay Peninsula and
islands.

inch long. Stipules connate, broad, with a short point.
Cymes terminal, elongate, 1J-4 inches long; peduncles 3
inches long, terminated by small dense cymes an inch long,
secondary branches scabrid. Bracts ovate-acuminate, ^ inch

with 5 short teeth, pubescent. Corolla ^ inch long
tube thick, short, pubescent; lobes 5, bluntly lanceolate, nearly
as long as the tube, densely woolly within the tube to the base.
Stamens barely protruding from the mouth of the tube;
filaments free nearly to the base ; anthers elliptic. Style

pulpy, I inch long when dry, on a pedicel ^ inch long.
Pyrenes flattened on the inner face ; back rounded, with five
ribs.
Gunong Tahan in the Gully, climbing on bushes by means
of its petioles.
