404 MERRILL. '■ 
acuminatis, iiiargine irregulariter acute dentato-lobatis ; floribus nias- 
culinis roseis, sepalis 2, orbicularibus^ 12 ad 15 mm longis, pctalis 2, 
obovatis; staminibus circiter 40; capsulis late obovatis, apice trnncatis^ 
inaequaliter 3-alatis, 2 cm longis, 3 ad 3.5 cm latis. 
A species most closely allied »to Begonia luzonensis Warb., differing 
Gspecialh^ in its much larger capsules. Peduncles^ petiolcSj both -sur- 
faces and margins of the leaves with few to many slender^ bro^vn, ciliato 
hairs 3 to 5 mm in length. Leaves ovate to oblong-ovate, chartaceous 
when dry, strongly obliquely inequilateral, 15 to 20 cm long, 6.5 to 13 
cm wide, base strongly cordate, apex slenderly acuminate, margins irre- 
gularly and rather coarsely acutely toothed-lobed, the sinuses often shallow, 
rounded, or the margin on the narrow side of the leaf entire or subentire; 
nerves 9, radiaic; petioles IG to 20 cm long. Inflorescence as long as 
the leaves, when young with many brown hairs, at maturity glabrous or 
nearly so, the peduncle up to 30 cm long, dichotoniously branched at 
the apex. Male flowers pink. Sepals 2, orbicular, rounded, 12 to 15 
mm in diameter.. Petals 2, obovate, 10 to 13 mm long, 8 mm wide, 
apex retuse. Stamens about 40; filaments slender, free, about 2.5 mm 
long; anthers obovate, 1 mm long. Female flowers not seen. Capsules 
very broadly obovate, unequally 3-wingGd, about 2 em long, 3 to 3.5 
cm wide, the apex truncate, the base rounded or subacute, the larger 
wing 1.5 cm wide, the two narrower ones less tlian 1 cm wide.

second with male flowers and mature fruits. Locally kuown to the Bontoc

Luzon, Province of Rizal, Montalban, Warhurg 13260, type in herb. Berol.!, 
Loher s. n., Merrill 106S, January, 1910. Possibly referable here is Bur. Bci. 
1295S Fenix, from Bauang, Union Province, Luzon, but the leaves are very 
iimch larger than in the type, and no fruits were collected. 
Through inadvertence the sepals and petals, in the original diagnosis, are 
described as 5 cra{!) long, and the i>edicels 1.5 to 2 m(!) long, apparent 
errors in both cases, the first for mm and the second for cm. The description 
of the flowers may have been drawn up from immature plants, for on both the 
other specimens cited above, which undoubtedly represent the species, have 
the sepals of the staminate flowers from 1 to 1.2 cm in length.

The type of this species was collected in the Philippines by Perrottet, and 
IS preserved in the Herbarium of the Museum of Natural History, Paris; this
