80. Cephaelis albiflora, n, sp. 



A tall branched shrub 6 feet or more high. Leaves mem- 

 branous, 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 

 ovate-acute, cuspidate. Floral bracteoles linear-lanceolate, 



. very small. Calyx-tube thick, with very short obscure lobes. 

 B Corolla-tube cylindric, half an inch long, with white hairs in 

 '^ the mouth; lobes ovate-acute, reflexed, the tips hairy. 

 Stamens projecting above the mouth of the tube, oblong- 

 obtuse, white. Style filiform, long. Stigma broad, trans- 

 versely oblong, bilobed. 



Common in woods by streams on the Padang. 

 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. 



82. PSYCHOTKIA BRACHYBOTRYS, Rtdl. 



Scandent ; stem herbaceous, branched; internodes an inch 

 long. Leaves subcoriaceous, lanceolate, base acuminate, apex 

 long-cuspidate, 7-nerved, glabrous, 4 inches long (including 

 the cusp half an inch long), i inch wide; petiole slender, ^-^ 

 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 

 long. Flowers in the terminal umbels about 20 ; pedicels in 

 flower, jl^ inch long, minutely pubescent. Calyx saucer- 

 shaped, 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 

 longer, stigmatic; arms 2, recurved. Fruit globose, white, 

 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. 



Distribution. Gunong Berumbnn near Telom. 



Near Ps. Knnstleri, King & Gamble, but has long cuspi- 

 date leaves and five-nbbed seeds. The specimens from which
