44. Begonia anisoptera sp. nov. 
Herba subtus foliis ad nervos petiolisque plus minus dense brunneo- 
villosis; foliis oblique ovatis, ba&i cordatiSj lobis vix superpositis, apice 
breviter acuminatis, margine integris vel subintegris; pedunculis foliis 
Bubaequilongis ; floribus masculinis 3 cm diametro; capsulis valde 3-alatis, 
alls 8 angustiSj rotundatis^ planis, 4 ad 5 mm latiSj capsulis aequalibus, 
ala tertia cucullataj 1.5 cm longa, 1.2 cm lata^ deorsum extensa. 
Stems prostrate, creeping, or the apical parts somewhat erect, more 
or less villous-ciliate, especially near the tips ; stipules oblong-ovate, about 
1 cm long, brown, membranaceous, acuminate, more or less ciliate. 
* 
Leaves obliquely ovate, 6 to 12 cm long, 4 to 8 cm wide, the base cordate, 
the lobes broad and rounded, the sinus narrow, apex mostly shortly and 
bluntly acuminate, sometimes slightly prolonged and nearly acute, the 
margins entire or subentire, not lobed, the upper surface glabrous, the 
lower ciliate-villous on the nerves, and with scattered, shorter, brown 
hairs on the surface; base palmately about 7-nerved; petioles 4 to 12 
cm long, when young densely covered with long, slender, brown, ciliate 
hairs, less densely covered when old. Inflorescence as long as or some- 
what exceeding the leaves, the peduncles slightly brown-ciliate. Flowers 
rather few, the staminate ones pink, 2 cm in diameter. Sepals 2, orbi- 
cular, 10 mm in diameter, rounded, with about 14 slender nerves, the 
back with scattered, short, brown, somewhat setose hairs. Petals 2, 
thinner than the sepals, obovate, about 10 mm long, 8 mm wide, the 
apex broad, somewhat retuse, the base gradually narrowed, faintly 8- 
nerved. Stamens about 35 ; anthers oblong, nearly 2 mm long, somewhat 
acuminate; filaments 1 to 1.5 mm long. Capsules strongly inequilater- 
ally 3-winged, the capsule proper 1 cm long, the two narrower wings as 
long as the capsule, 4 to 5 mm wide, rounded, the apex acute, the base 
retuse, the larger wing 1.5 cm long, 1.2 cm wide, strongly cucuUate, 
rounded, the apex acute, the base extended downward below the capsule 
and rounded. Placentas 2-partite. 
Mindanao, District of Zaniboanga, Zami>oaiiga, Merrill 5482, October 10, 1906 
(type), on somewhat shadded cliffs in forested ravines, altitude less than 100 m; 
Port Banga, For Bur. 12SJi2 Hutchinson, April, 1908, on boulders in forests 
altitude about 100 m. 
A species quite different from all other Philippine forms of the section known 
to me, well characterized by its very unequally Swinged capsules, but especially 
by the large wing distinctly eucullate, much longer than the capsule, and produced 
below it. When fresh the leaves are purple beneath and more or less blotched 
with gray above. Another unusual character, so far as the Philippine species 
are concerned, which is shared with the next species, is the sepals being more or 
less ciliate on the back.
