Herba subtus foliis ad nervos petiolis pedunculisque brunneo- 
setosis, caulibus prostratis; foliis confertis, longe petiolatis, 
usque ad 22 cm longis, oblique ovatis, acuminatis, valde inae- 
quilateraliter cordatis, margine undulatis vel parce undulato- 
lobatis; inflorescentiis folia subaequantibus, multifloris, floribus 
masculinis circiter 11 mm diametro, sepalis orbiculari-ovatis, 
quam petalis multo latioribus; staminibus circiter 60; capsulis 
circiter 1 cm longis, 1.5 cm latis, subaequaliter 3-alatis, alis 
rotundatis. 
Stems creeping, rather stout, more or less brown-setose and 
with brown, ovate, acuminate stipules about 1 cm long, the 
leaves crowded, the peduncles, leaves on the nerves beneath, and 
petioles prominently brown-setose, the petioles 11 to 18 cm long. 
Leaf-blades obliquely ovate, strongly inequilaterally cordate, 
submembranaceous when dry, 15 to 22 cm long, 10 to 15 cm 
wide, acuminate, margins undulate or somewhat undulate-lobed, 
the upper surface somewhat olivaceous when dry, slightly shin- 
ing, minutely puncticulate, glabrous, the lower surface greenish- 
or brownish-olivaceous, the nerves in strong contrast, brown, 
brown-setose on the nerves and primary reticulations, every- 
where white-puncticulate, the nerves about 10. Inflorescence 
about as long as the leaves, long-peduncled, ample, with both 
male and female flowers. Male flowers white or very pale-pink, | 
about 11 mm in diameter. Sepals orbicular-ovate, rounded, 
about 5.5 mm long, 5 mm wide. Petals oblong-obovate, rounded, 
narrowed below, as long as the sepals, about 2 mm wide. Sta- 
mens about 60; anthers 0.6 mm long, obovoid, as long as the 
filaments. Female flowers: Sepals 2, broadly elliptic-ovate, 
rounded, about 6 mm long, 5 mm wide. Petals 2, as long as 
the sepals, oblong-obovate, 2.5 mm wide. Styles 3, about 3 mm

Herba erecta, ramosa, B. cwmingii affinis, differt foliis latio-

culinis multo minoribus, petalis circiter 5 mm longis. 
An erect branched herb, nearly glabrous. Leaves inequilat-
