Haenke. It is known to the Visayans in Negros as bituca or malangpang. 
Endemic. 
16. Begonia mearnsii sp. nov. 
Herba suberecta, omnibus partibus, praesertim junioribus, dense cris- 
pato-fulvo-villosis ; foliis suborbieularibus vel subreniformibus, usque ad 
10 cm longis, breviter acuminatis, leviter lobatis, basi circiter 7-nerviis, 
inaequilateraliter cordatis; inflorescentiis valde bracteatis; floribus mas- 
culinis longe pedicellatis, circiter 1.5 cm diametro. 
An herbaceous or suffrutescent plant, suberect, or the older parts of 
the stems more or less decumbent and rooting at the nodes. Stems brown, 
more or less sulcate when dry, more or less' ciliate with crisped, often 
matted, long, brown hairs, all younger parts of the plant densely so, 
the inflorescence, petioles, and fruits with similar hairs. Leaves sub- 
orbicular or subreniform, up to 10 cm long and nearly as wide, or 
sometimes wider than long, membranaceous, the upper surface brown, 
with very few, scattered, short hairs, the lower surface much paler, 
rather, strongly brown-pubescent on the nerves, the entire lower surface 
densely covered with small, whitish, sublepidote spots, the base shallowly 
and inequilaterally cordate, the apex shortly and rather broadly ac- 
uminate, the margins irregularly and shallowly lobed, the sinuses shal- 
low, broad, none of them exceeding 1 cm in depth ; basal nerves about 7, 
distinct, some of them forked above ; petioles 3 to 9 cm long ; stipules 
membranaceous, oblong, about 1 cm long. Staminate and pistillate 
inflorescences similar, few-flowered, terminal, 5 to 12 cm long, long- 
peduncled, each subtended by a terminal leaf and a pair of bracts, the 
bracts about 1 cm long, ovate or oblong-ovate, densely brown-pubescent, 
the flowers crowded near the apex of the peduncle, subtended by several, 
more or less reniform, ciliate, pubescent, somewhat imbricate bracteoles 
nearly 1 cm in length. Staminate flowers: Pedicels slender, solitary, 
about 1.5 cm long. Sepals 2, orbicular-obovate, about 8 mm in dia- 
meter, equilateral, rounded, about 7-nerved, the back with few, scattered, 
stout, brown hairs on the nerves. Petals none. Stamens about 16, 
alternately arranged along the somewhat elongated torus, the filaments 
less than 1 mm long, the anthers narrowly oblong-obovoid, rounded 
or retuse, about 1.5 mm long. Pistillate flowers: Sepals 5, inequi- 
laterally obovate, about 9 mm long, 7 to 8 mm wide, nerved and pubes- 
cent like those of the male flowers. Ovary densely brown-pubescent, 3- 
celled, 3-winged; styles 3, free or nearly so, about 3 mm long, divar- 
icately forked. Young fruit about 8 mm long, 3-winged, pubescent.

A species manifestly referable to the section Petermannia, differing from all 
the species of that group known to me in its dense, brown indumentum.
