broswn-pubescent, the hairs similar to those on the branchlets, the 

 apex slenderly acuminate, somewhat falcate, the base not at all or 

 but slightly narrowed on the broadly rounded wider side, slightly 

 narrowed and acute or somewhat cordate on the narrower side, 

 the margins distantly and slightly toothed, not at all lobed, the 

 base 6 or 7-nerved, the primary lateral nerves above the base 

 2 on the narrower side, usually 3 on the broader side, ascending, 

 forked, prominent on the lower surface, the reticulations lax, 

 indistinct; petioles brown-pubescent, 2 to 4 mm long; stipules 

 oblong, submembranaceous, about 7 mm long, their midribs 

 excurrent as long and slender apiculi. Staminate and pis- 

 tillate flowers on separate inflorescences on the same plant, in 

 rather lax, few-flowered, terminal cymes, sometimes reduced to 

 two or three, long-pedicelled flowers. Staminate flowers : Sepals 

 2, pure white to somewhat pink, broadly ovate, membranaceous, 

 glabrous, 2 to 2.5 cm long, 2 to 2.3 cm wide, the base broadly 

 cordate, the apex broadly rounded. Petals none. Stamens about 

 50, inserted on the slightly elongated torus, the filaments 2.5 

 mm long, the anthers narrowly oblong-obovoid, about 1.5 mm 

 long. Bracts' membranaceous, apiculate, about 7 mm long. 

 Pistillate flowers: Bracts elliptic-ovate, membranaceous, 1 cm 

 long, apiculate, two subtending each flower, deciduous; pedicels 

 slender, pubescent, about 2.5 cm long. Sepals 5, narrowly ovate, 

 membranaceous, acute or obtuse, about 2.3 cm long. Stigmas 

 spirally arranged. Capsules turbinate, including the wings 

 about 1.5 cm long and wide, subequally 3-winged, the apex trun- 

 cate or somewhat cordate, the tips of the wings broadly rounded, 

 the base acute or subtruncate, broadly rounded. ,

A striking species, manifestly closely allied to Begonia rtterHttii Men*., 

 from which it is distinguished by the numerous characters indicated in 

 the diagnosis. It is remarkable for its large size, the development of 

 woody tissue in the stems, and its very large flowers.
