SiKKiM, alC 3000-8000 ft., the ' commonest species. Khasia Mts., alt. 4000- 

 8000 ft.; ff. /'. d;^ 2\ 



- Very variable in size and habit, stemless or stem leafy, always easily recognised 

 by the peltate leaves. Rootstock of one or few tubers. iStem generally 0. Kadical 

 leaves (on petioles 4-10 in.) often 6 in., sometimes nearly regularly ovate acuminate, 

 ^cutely 3-lobed or orbicular with numerous acute lobes, serrate or doubly serrate or 

 less often almost entire, usually nearly glabrous but often slightly pubescent on the 

 nerves beneath sometimes weakly pilose above ; stipules ovate, deciduous, glabrous 

 or nearly so. Scape 1 ft., usually repeatedly dichotomous with long lower branches, 

 ^n entirely naked ; bracts caducous, caulescent and leafy ; flowers rather small, 

 ^Se. Male: sepals 2, caducous; petals 2, smaller; stamens shortly moniuielphous, 

 sometimes 8-30; anthers obovoid; <!onnective not produced. Female: perianth- 

 segments 4-6 ; styles 3, nearly separate, 2-fid near the top, stigmas in large specimens 

 ^«^4ortuous, in small simple lunate. Capsule ^ by ^ in. including the wings, styles 



I r^^^'^^^^^^t, upper margin of the wing horizontal, narrow between the two very 

 w^'"^^ wings, the other faces broader below ; dehiscing first by 4 lines, two on 

 ^*Bher side of each of the two narrow wings. Secc^s short^ellipsoid. — All three varie- 

 P*r^=i are equally common in Sikkim and pass into each other: only the typical 



J. vUttibeen collected in Khasia. The plant is believed to be very plentiful in West 



, ^O'otan and East Nipal, but all the numerous Himalayan examples at Kew are 

 ,. m Sikkim itself. As regards the name; Wallich's Begonias are greatly mixed;
