long, red-brown with obtuse edges.—The material for this species is fem. only, and 
quite insufficient. Weddell describes the achene as marbled and smooth not granular, 
I find a herbaceous granulate coat covering a smooth endocarp. 
18. P. obliqua, Hook.f. ; glabrous, stem slender, leaves 3-5 in. long- 
petioled broadly obliquely ovate acuminate serrulate 3-nerved, base rounded 
or cordate, stipules oblong, cymes slender long-peduncled, fem. dorsal sepal 
longest, achenes minute straight with an intramarginal rugose or granular 
ridge, the faces nearly smooth.

The very oblique broadly ovate leaves of this species which is a native of low 
levels, and the concentric ridge on the otherwise nearly smooth achenes which are 
only 4 in. long, are its best characters, otherwise it is very near P. bracteosa.

19. P. cordifolia, Hook f.; tall, stout, quite glabrons, leaves large 
broad long-petioled oblique orbicular-ovate or elliptic cuspidate or acu minate 
obtusely serrate 3-nerved, base cordate or rounded, petiole 3-6 1n., stipules 
rather large broad persistent, male cymes very long-peduncled paniculately 
branched, sepals obtuse, dorsal of fem. fl. longest.

Weddell has named one Sikkim specimen P. trinervis, which it does not resemble, 
and a Khasia one P. bracteosa. 
20. P. fruticosa, Hook. f.; shrubby, quite glabrous, stem branched 
terete woody, leaves 3—4 in. long-petioled in equal pairs elliptic or oie 
lanceolate acute at. both ends obscurely obtusely serrate 3-nerved, stipules 
very short, male cymes sparingly branched, peduncles longer than NN 
petioles, flowers in small remote clusters minute, fem. cymes small sessiie; 
flowers crowded, dorsal sepal longest, achenes very minute with an intra- 
marginal granular ridge. 
PERAK; at Goping, King's "Collector.—Nearly allied to P. smilacifolia, but the 
stems are quite terete, and the minute achenes qs in. long are very different. :
