branous, glabrous, 2-4 in. long, 1-2 in. wide, oblong, cordate, acumi- 
nate, l-nerved, sinuate, sometimes 3-lobed, lobes pointed. Tendrils 
axillary, some sterile, others fertile. Flowers numerous, small, in ter- 
minal or axillary panicles. Calyx deeply 5-parted, segments narrow, 
evate-oblong, linear-spotted, membranous at the edges, valvate in the 
ud. Petals membranous, oblong, obtuse, jagged at the edges, shorter 
than the segments of the calyx. Corona of fine hairs, sometimes nearly

(cum ic. xylog.) 
Flowers dichlamydeous, unisexual. Male fl.: Sepals 5, distinct, 
originally equal and equidistant, afterwards, owing to the irregularity 
of two of the petals, two of the sepals are widely separated ag 
each other. Petals 5, quincuncially imbricate, 3 outer ones flat, 2 
inner ones larger and concave. Corona none. Stamens 10, mona- 
elphous at the base, 5 fertile opposite to the petals, 5 sterile; fila- 
ments flat, twisted; anthers subglobose, 1-celled, attached to the fila- 
ment on the dorsal surface, originally introrse, but from the cur- 
vature of the filament ultimately extrorse, dehiscing longitudinally by 
+ Single chink ; pollen spherical; connectives of the anthers? pro-
