more, the stems and branches slender, pale-brown when dry, 
sometimes geniculate and emitting small roots at the nodes. 
Leaves lanceolate, when dry membranaceous, green, of nearly 
the same color on both surfaces, glabrous, 8 to 12 cm long, 1.5 
to 2.5 cm wide, narrowed below to the acute or obtuse, nearly 
equal or slightly inequilateral base, not at all cordate, the apex 
very long and slenderly caudato-acuminate, the acumen sharply 
toothed, the margins in the basal part entire, in the median por- 
tions coarsely and irregularly sinuate-lobed, about 3 lobes on 
each side of the midrib, the lobes acute, broad, the sinuses mostly 
rather shallow, rounded; stipules lanceolate, long and slenderly 
aristate-acuminate, about 10 mm long, 2 mm wide at the base; 
petioles slender, 1 to 2 cm long. Inflorescence terminal, 9 cm 
long or less, the branches and branchlets rather few, very slender, 
one or more female flowers at the base, the male flowers above, 
apparently rather numerous but early deciduous. Male flowers : 
Sepals 2, orbicular, broadly rounded, in nearly mature bud 4 
mm in diameter. Petals none. Stamens about 25, the anthers 
oblong-obovoid, nearly 1 mm long. Capsules about 8 mm long, 
including the 3 subequal wings about 1.4 cm wide, the base trun- 
cate, the apex broadly rounded or subtruncate, the wings thin, 
rounded.

Most closely allied to Begonia littleri Merr., also known only from Basi- 
lan, but distinguished by its entirely different leaves, and its equally 
3-winged capsules. From B. lo-ngistipula Merr. and B. palawanensis it 
not only differs in its much narrower, differently shaped leaves, but also 
in its very much smaller capsules. 
BEGONIA LACERA sp. nov. § Petermannia. 
Species praecedente affinis, differt foliis brevioribus angus- 
tioribusque, usque ad 7 cm longis, 1 cm latis, irregulariter lace- 
rato-lobatis, stipulis brevioribus, circiter 6 mm longis, sepalis 
(fl. $ ) late ovatis, subacutis. 
An erect, branched, slender herb about 40 cm high, quite 
glabrous, the branches and branchlets reddish-brown when dry, 
slender. Leaves lanceolate, thinly membranaceous when dry, 
green, 3 to 7 cm long, about 1 cm wide, narrowed to the sub- 
equilateral acute or obtuse base, the apex very long and slenderly 
caudate-acuminate, the margins irregularly lacerate-lobed in the 
median portion, the basal portion entire, the long and slender 
acumen sharply and rather coarsely toothed, the lobes few, 
rather narrow, acute or acuminate; petioles 5 mm long or less;
