wide, equally 3-winged, broadly rounded at the base, the apex 

 truncate, the upper outer angles sharp. 



Mindanao, Bukidnon Subprovince, Sumilao, Bur. Sci. 157SS 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 ; f oliis usque ad 13 cm longis, valde inaequi- 

 lateralibus, oblongis vel ovato-oblongis, acuminatis, irregulariter 

 lobatis denticulatlsque, lateraliter cordatis, basi baud 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 much 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
