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

 smaller flowers, and decidedly larger fruits.

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

 ribus, usque ad 9 cm latis, minus pubescentibus, floribus mas- 

 culinis multo minoribus, petalis circiter 5 mm longis.
