The only .species of the section known from the Philippines, extending from 
nortliern Luzon to ^Mindanao and tlie Sulu Archipelago. According to Warburg 
it is closely allied to Begonia heteroclinis Miq., of northeastern Celebes. 
I am indebted to Dr. F. Gagnepain of the Museum of Natural History, Paris, 
for a sketch of the type specimen of Begonia salaziensis var. calleryana; the 
specimen is fragmentary/ but is unquestionably identical with \yarburg's Begonia 
pseudo-later alls. 
Endemic.

Suffruticosa, erocta, circiter 80 cm alta, pance ramosa, partibus Junior- 
ibus subtus foliis ad nervos plus minus breviter bmnneo-pubegcentibiis ; 
foliis valde inequilateralibus, basi oblique cordatis, apice acuminatis, 
margine denticulatis et leviter, distantcr, breviter lobatis, palmatinerviis ; 
inflorescentiis axillaribus, quam petiolus multo brevioribus; floribus in 
apice peduuculorum solitariis vel paucis, bracteis bractcolisque suffultis;

A suffrutescent, erect, slightly branched plant about 80 cm high- 
Stems terete, glabrous, not striate, 5 to 7 mm in diameter, dark-brown 
or nearly black when dry, the younger parts and petioles rather densely 
pubescent with dark-l)rown, short hairs. Leaves membranaceous or sub- 
membranaceous inequilaterally and obliquely oblong or oblong-ovate, 9 
to 13 cm long, 4 to 7 cm wide, the base strongly ol)liquely cordate, the 
broader lobe rounded, 2 to 3 cm wide, the narrower one obtuse, less than 
1 cm wide, the apex rather abruptly and slenderly acuminate, the acimien 
1 to 1.5 cm long, the margins irregularly dentate, and sometimes with 
from one to three, ovate, acute lobes, but these lobes never more than 1 
cm deep, the upper surface glabrous, dark-brown, somewhat shining, the 
lower much paler, the nerves brown-pubescent, the whole surface covered 
with numerous, small, whitish, lepidote-like spots; nerves palmately 
arranged, about 12, distinct, mostly forked, brown, much darker than 
the other parts of the lower surface; petioles pubescent, about 2- cm 
long- stipules oblong, 1.5 cm long or less, abruptly apiculate-acuminate, 
brown membranaceous, glabrous or nearly so. Inflorescence, both stam- 
inate and pistillate, axillary, much shorter than the petioles, more or less 
pubescent. Staminate flowers, one to three, fasciculately arranged at 
the end of the short, solitary, about 4 mm long peduncle, each subtended
