BEGONIACEAE 
BEGONIA Linnaeus 
BEGONIA COLLISIAE sp. nov. § Diploclinium. 
Herba, pedunculis foliisque utrinque ad nervis plus minusve 
ferrugineo-villosis ; foliis longe petiolatis, in ambitu late ovatis, 
usque ad 20 cm longis, inaequilateralibus, basi lateraliter cor- 
datis, apice leviter acuminatis, profunde subpalmatim lobatis, 
lobis numerosis, oblongis, 2 ad 5 cm longis, irregulariter et 
grosse dentato-serratis vel lobulatis ; inflorescentiis longe pedun- 
culatis, dichotome ramosis, parce glandulosis, paucifloris ; floribus 
circiter 3 cm diametro; sepalis late ovatis, circiter 11 mm latis; 
petalis sepalis aequantibus, 6 ad 7 mm latis. 
An herb, from short, rather stout, prostrate rhizomes about 
1 cm in diameter. Leaves long-petioled, in outline broadly ovate, 
15 to 20 cm long, 10 to 15 cm wide, when dry submembranaceous, 
the upper surface olivaceous, somewhat shining, the lower brown- 
ish, both surfaces more or less ferruginous-villous on the nerves, 
when fresh the nerves beneath red, inequilateral, subpalmately 
and conspicuously lobed, the lobes oblong, 2 to 5 cm long, 2 to 3 
cm wide below, all acute or acuminate and irregularly and 
coarsely dentate-serrate or lobulate, the primary lobes usually 
about 10, the base of the leaf laterally cordate, the sinus narrow, 
2 to 4 cm deep, the basal lobes broadly rounded, often overlap- 
ping; petioles brown when dry, ferruginous-villous. Peduncles 
nearly glabrous, up to 20 cm in length, the younger parts spar- 
ingly glandular, dichotomously branched at the apex, the pri- 
mary branches about 4 cm long, few-flowered. Staminate flowers 
pink and white, about 3 cm in diameter. Sepals broadly ovate, 
about 14 mm long, 11 mm wide, rounded, with few, small, widely 
scattered, brown glands. Petals oblong-obovate, as long as the 
sepals, 6 to 7 mm wide. Stamens many, the anthers narrowly 
obovoid, 0.8 mm long, equaling or shorter than the filaments. 
Pistillate flowers and fruits unknown.

This species is remarkably distinct from all previously de- 
scribed Philippine ones in the section Diploclinium, and is 
strongly characterized by its deeply lobed leaves, the lobes being 
usually about 10 in number, up to 5 cm in length, and coarsely 
and irregularly toothed and lobulate.
