BEGONIACEAE 



BEGONIA Linnaeus 

 BEGONIA COLLISIAE sp. nov. § Diplodinium. 



Herba, pedunculis foliisque utrinque ad nervis plus minusve 

 f errugineo-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 Diplodinium, 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.
