serrate, glabrous and dull on both surfaces; lateral nerves 6-10 on 
each side, slender, slightly raised on both surfaces, fading and branched 
towards the margin; cross-nerves faint and very lax; glands at the 
base of the leaf cupular, stipitate, coriaceous; petiole slender, 3-1} in. 
long, very sparingly pubescent ; stipules deciduous. Flowers moneecious. 
Racemes terminal, up to 6 in. long, a few female flowers at the base of 
each, the remaining upper part consisting of numerous males, or all 
male; axis laxly villous with stellate hairs; bracts small, subulate, 
4 lin. long. Male flowers: pedicel 1—2 lin. long, terete, pubescent. 
Sepals 5, oblong-elliptic, obtuse, 14 lin. long, ¢ lin. broad, slightly 
membranous, stellate-pubescent on the back, glabrescent within. 
Petals linear-oblong, obtuse, 1 lin. long, glabrous outside, pilose at the 
base and apex within. Disk-glands small, fleshy, glabrous. Stamens 
20; filaments slender, glabrous. Female flowers: pedicel stout, 
1 lin. long, pubescent. Sepals oblong, obtuse, 14 lin. long, ? lin. broad, 
stellate-pilose outside, glabrous within, except for a few stellate hairs 
towards the apex. Petals reduced to 1 or 2, linear-filiform, 2 lin. long, 
pilose. Disk fleshy, villous. Ovary tomentose; styles 5, recurved- 
spreading, bipartite to near the base, segments linear, entire, 1 lin. 
long, glabrous. Capsule ellipsoid-globose, obtusely trilobed, nearly 
3 in. in diam., scaly with the persistent bases of the stellate hairs ; 
exocarp and endocarp thin. Seeds oblong-ellipsoid, 43 lin. long, 34 lin.

Branches terete, rather densely covered with lenticels; young flower- 
ing branchlets rather slender, woolly-tomentose when young, at length 
becoming nearly glabrous. Leaves ovate or ovate-lanceolate, acutely 
and rather long-acuminate, rounded and more or less cordate at the 
base, 2-44 in. long, 3-24 in. broad, irregularly serrate, membranods, 
stellate-tomentose below and pubescent above when young, at length 
quite glabrous, digitately 5-nerved from the base,. remaining lateral 
nerves 4~5 on each side, looped and branched some distance from the 
margin, distinct on both surfaces; petiole 3-1} in. long, with 2-4 
scattered glands at the apex, tomentose ; stipules deciduous, linear- 
lanceolate, 3 lin. long, nearly glabrous. Flowers monecious. Racemes 
terminal, 14-2 in. long, the lower two-thirds containing about 12 
female flowers, the upper third with about the same number of males ; 
bracts similar to the stipules, but stellate-pubescent ; female pedicels 
about 1} lin: long, stellate-pubescent, the males 2 lin. long. Male 
flowers: Sepals 5, oblong-ellipsoid, 14 lin. long, 1 lin. broad, thin, 
striate, glabrous on both sides, rather densely ciliate in the upper hal . 
Petals 5, narrowly elliptic, subacute at both ends, 2 lin. long, § lin. 
broad, trinerved, glabrous on both surfaces, densely ciliate. Disk-
