1. D. paradoxa, A. Chev. in Bull. Soc. Bot. France, \xi, Mém. 8e, 298. 
A small shrub 3-44 ft. high, everywhere glabrous. Stems slender, tough, 
branched at the apex, evidently without whitish latex in cortex. Leaves 
alternate, petiolate, oblong-acuminate, subacute, rounded or wedge-shaped 
at the base, 43-7 in. long, 13-23 in. broad, papery, very slightly crenulate ; 
midrib conspicuous on both surfaces, with 7-8 pairs of lateral nerves ; 
venation not at all prominent; petiole 2-3 lin. long, deeply channelled 
above ; stipules lanceolate, very acute, about 1 lin. long, caducous. Re- 
ceptacle woody, solitary in the axils of the upper leaves, }—} in. long, +4 
in. broad and subtriangular at the apex, divided into 3 thick short rounded 
lobes, clothed with flowers on the whole surface and also below. Involucre 
absent. Female flowers not more than 4 lin. in diam., sessile, clustered on 
small swellings of the receptacle, inserted in the axils of scariose ovate-acute 
} lin.-long bracts. Sepals 4-5, suborbicular, concave, } lin. long, much 
imbricate, supported on the outside by 2-3 scarious bracts. Ovary 3 lin. in 
diam., flattened and disc-like. Fruit with peduncles ,1,—+ in. long, articulate 
above the receptacle, at first of a dull green, when mature red, glabrous, 
spherical or somewhat turbinate at the base, 5-6 lin. in diam., with a 
fleshy exocarp, and a woody whitish-yellow endocarp about 1 lin. thick.

8e, 302. A dicecious woody plant, sarmentose, climbing, 10-16 ‘ft. long. 
Stems ash-colour, subtriquetrous, 2-34 lin. thick, bearing a pair of gibbous 
vesicles 11-24 lin. in diam. (? galls) at the points of division. Young 
branches glabrous or slightly puberulous at the top. Leaves long-stalked, 
thinly membranous, oval, apex obtusely acuminate, base subcordate, 
margin entire, lateral nerves in 4 to 5 pairs, the lowest pair basal, 
glabrous, or with a few stinging hairs on the nerves when young, upper 
face shining ; petioles slender, glabrous, 3-21 in. long. _ Stipules linear- 
subulate, 2 lin. long, soon falling. Male flowers in reddish-green corym- 
biform axillary cymes, 14-3 in. long, generally in the axil of the leaf- 
sears on old branches ; peduncle 4-14 in. long, very finely puberulous, 
pedicels and rhachis very fleshy, yellow-green. Flowers in umbels 
of 5 to7 at the end of branches of the second and third order ; pedicels 
very slender, 3-1 lin. long; bracts oval, less than } lin. long; perianth- 
segments 5, oval, subobtuse, $ lin. long, puberulous on the outside. 
Female flowers in corymbiform cymes, 3-11 in. broad ; peduncle glabrous,

persistent small branched brown-purple laciniate outgrowths beset with
