obovatis vel late oblanceolato-obovatis, acuminatis, leviter irregulariter 
denticulatis, vix lobatis, basi angustatis, penninerviis ; floribus parvis, 
breviter pedicellatis, in fasciculis axillaribus dense dispositis, pedicellis 
bracteolis nnmerosis suffultis. 
A suffrutescent erect plant 0.6 to 1.2 m high, not or but slightly 
branched, the lowermost nodes root-bearing. Stems dark-brown, terete, 
rather stout, about 6 mm in diameter below, longitudinally striate, 
pubescent with short, stout, dark-brown, more or less scattered hairs. 
Leaves alternate, membranaceous, inequilaterally oblong-obovate to 
broadly oblong-oblanceolate, 13 to 18 cm long, 5 to 7 cm wide, the apex 
shortly but sharply acuminate, the base narrowed, wider on one side of 
the midrib then on the other, the widest side narrowed to the abruptly 
rounded base, the other side acute, the margins distantly and irregularly, 
and usually doubly denticulate, scarcely lobed, the upper surface quite 
glabrous, the lower with scattered, short, brown hairs on the nerves, and 
the whole lower surface densely covered with small, whitish, sublepidote 
spots; petiole 5 mm long or less; midrib prominent, the lateral nerves 
about 7 on each side of the midrib, ascending, nearly straight, most of 
them forked; stipules brown, pubescent, lanceolate, prominently acum- 
inate, 1 to 1.5 cm long. Flowers fascicled in the axils of the leaves, 
numerous, crowded, the pedicels about 4 mm long, each subtended by a 
whorl of about 5, lanceolate, acuminate, ciliate, brown braeteoles 2 to 3 
mm long. Staminate flowers: Sepals 2, ovate, obtuse, about 8-nerved, 
just before anthesis about 6 mm long. Stamens about 30 ; anthers ellip- 
soid or oblong-ellipsoid, retuse, about 1 mm long, the filaments about as 
long as the anthers. Pistillate flowers not seen. Capsules glabrous, 
shortly peduncled or subsessile, obovate in outline, about 1 cm long, 
truncate, base acute, 3-celled, the placentae forked, 3-winged, the wings 
2 to 3 mm wide. 
Mindanao, District of Zamboanga, Port Banga, For. Bur. 9248, 9316 (type) 
Whitford & Hutchinson, December 26, 1907, and January 13, 1908, in canyons, 
5 to 30 m above sea level. 
A species well characterized by its dense, fascicled inflorescence, in this 
character approaching Begonia fasciculata Jack of Sumatra, but otherwise ap- 
parently not closely allied to that species. 
6. Begonia agusanensis sp. nov. 
Herba erecta, . simplex vel parce ramosa, 25 ad 40 cm alta, ramulis 
petiolisque junioribus sparse setosis; foliis breviter petiolatis, inaequia- 
teraliter oblongo-obovatis, in siccitate membranaceis, glabris, usque ad 
13 cm longis, basi angustatis, anguste oblique cordatis, margine in 
partibus superioribus plus minus lobato-dentatis, apiee acuminatis ; petiolo 
3 ad 10 mm longo; paniculis in axillis superioribus, 3 ad 5 cm longis, 
ramulis tenuibus; floribus masculinis parvis, sepalis 2, ovatis, petalis 2, 
quam sepala multo angustioribus ; capsulis aequaliter 3-alatis, 10 mm 
longis.
