60 Materials for a Flora of the Malayan Feninsula, 



reniform and blunt, or sometimes with a short broad abrupt apiculus, 

 the basal sinus deep and the edges wavy and minutely denticulate or 

 crenate; or reniform-cordate, gradually tapered to the sub-acute apex, 

 the margins slightly lobulate-dentate, the lobes denticulate, the basal 

 sinus small: length of the reniform over 4 to 6 in.; breadth .5 to 8 

 in., of the ovate-reniform 1-5 to 3 in.; breadth 1 to 3 in.; petioles of 

 the radical leaves 1 to 3 in. ; of the cauline '5 to 2*5 in. ; both surfaces 

 with numerous adpressed white stellate hairs, the lower with small 

 oblong white scales also; main-nei-ves 7 to 11, radiating from the base, 

 prominent on the lower surface; petioles unequal, '5 to 3 in. long, pube- 

 scent. Stipules small, oblong-lanceolate, slightly oblique, blunt, glab- 

 rous. Inflorescence 3 to 8 inches long, sparsely stellate-pubernlous ; the 

 peduncle very slender; branches few, short, filiform, few-flowered; 

 bracts minute ("05 to '1 in. long) bluntly lanceolate, rather densely ad- 

 pressed-pubescent externally, the upper in whorls of three. Flowers 

 small, pink, glabrous. Males about '2 to -25 in. in diam. : sepals 2, 

 roundish ; petals 2, narrower, obovate ; staviens about 20, monadel- 

 phous; anthers obovoid, connective not produced. Female perianth- 

 segments 5, the inner gradually smaller. Styles 2, combined for half 

 their length, stigmas lunate. Capsule about "3 in. broad and slightly 

 longer, the posterior wing the largest. Seeds ovoid, shining, brown, 

 deeply pitted. A. DC. Prod. XV, Pt. I, 354; Kurz in Journ. As. S<>c.

5. Begonia andamensis, Parish ex Clarke in Hook, fil, Fl. Br. 

 Ind. II, 650. Like the reniform-leaved form of B. sinuata, but the 

 hairs on the surfaces of the leaves scanty : the inflorescence usually 

 longer audits peduncle and branches much stonter ; the bracts glabrous, 

 longer (35 to '5 in.) and blunter and the male flowers ('5 in. across) 

 and capsules ("6 in. across) longer and more numerous than those of 

 B. sinuata.

This ought probably to be regarded as a variety of B. sinuata. Actual speci- 

 mens of the two look more different than written descriptions lead one to suppose ; 

 I therefore retain this as a species. 



6. Begonia debilis. King n. sp. A slender weak herb, about 6 to 8 

 inches high, caulescent. Leaves thin, narrowly reniform, blunt or sub- 

 acute ; the base unequal, rounded at both sides but one auriculate and
