wide, equally 3-winged, broadly rounded at the base, the apex 
truncate, the upper outer angles sharp. 
Mindanao, Bukidnon Subprovince, Sumilao, Bur. Sci. 157 S3 Fenix, 
August 4, 1912, on wet rocky slopes, locally known as tabaring. 
A species with the vegetative characters of Begonia littleri Merr., in 
general similar to that species, and to the allied forms B. brevipes Merr., 
B. longistipula Merr., and B. palawanensis Merr. It is at once distin- 
guished by its large male flowers, which in this species are about 2 
cm in diameter, while in the above species they do not exeeed 1 cm 
in diameter. 
BEGONIA LATISTIPULA sp. nov. § Petermannia. 
Herba erecta, ramosa, ramis ramulisque crassis, teretibus, 
parce setoso-ciliatis ; foliis usque ad 13 cm longis, valde inaequi- 
lateralibus, oblongis vel ovato-oblongis, acuminatis, irregulariter 
lobatis denticulatisque, lateraliter cordatis, basi haud angustatis ; 
stipulis 1.5 ad 2 cm longis, ovatis, cilato-setosis ; floribus paucis, 
axillaribus, fasciculatis, $ 1 vel 2, longe pedicellatis, circiter 3 
cm diametro, 9 solitariis, subsessilibus ; capsulis aequaliter 3- 
alatis, apice truncatis, basi acutis, circiter 1.5 cm longis, 2 cm 
latis. 
An erect, sparingly branched, rather stout herb at least 50 
cm in height, the stems and branches, stipules, petioles, and 
young leaves on the lower surface more or less setose-ciliate. 
Branches terete, reddish-brown when dry. Leaves thinly mem- 
branaceous when dry, strongly inequilateral, oblong to ovate- 
oblong, somewhat falcate, 9 to 13 cm long, 3 to 5 cm wide, 
when young ciliate-setose with brown hairs on the nerves of 
the lower surface, becoming glabrous or nearly so, the margins 
irregularly lobed, the broader side with one or two rather coarse, 
acute lobes and 5 or 6 mueh smaller ones more like coarse teeth, 
irregularly ciliate-denticulate, the apex rather slenderly acu- 
minate, the base scarcely narrowed, prominently laterally cord- 
ate, the lobes rounded, that of the broader side very much wider 
than that of the narrow side; petioles 8 to 15 mm long, rather 
densely setose-ciliate with brown hairs; stipules ovate, some- 
what inequilateral and slightly falcate, membranaceous, 1.5 to 
2 cm long, 1 to 1.2 cm wide, prominently ciliate-setose on the 
margins, the midrib excurrent as a short mucro. Flowers ax- 
illary, fascicled, one male and one female, or two males and 
one female in the same axil. Male flowers : Pedicels slender, up 
to 2 cm long. Sepals 2, broadly ovate, rounded, 1.5 cm long. 
Petals none. Stamens about 20, inserted on the elongated torus ; 
anthers narrowly ovoid, 2 mm long, rounded. Capsule subses- 
sile or shortly pedicelled, triangular, the base acute, the apex
