Very variable in size and habit, stemless 0* stem leaft-, always easily recognised 

 by the peltate leaves, Ifootsioclc of one or few tnbers. Stem generally 0, Radical 

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

 acutdv 3-lobed or orbicular with numerons acute lobes, serrate or doubly serrate or 

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

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

 or nearly so. Scape 1 ft., usuajly repeatedly dichotomous with long lower brajiches, 

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

 rose. Maim : sepals 2, caducous ; petals 2, smaller ; stamens shortly monadelphous, 

 sometimes 8-30 ; anthers obovoid ; connective not produced. Femaie : perianth- 

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

 2 tortuous, in small simple lunate. Ca;paide ^ by ^ xd,. including the wings, styles 

 persistent, upper mai^n of the wing horizontal, narrow between the two very 

 narrow wings, the other faces broader below; dehiscing first by 4 lines, two on 

 either side of each of the two narrow wings. Seeds short-ellipsoid,— All three varie- 

 ties are equally common in Sjkkim and pass into each other: only the typical 

 ^ has been collected in Kbasia. The plant is believed to be very plentiful in West 

 Bhotan and East Ifipal, but all the numerous Himalayan examples at Kew are 

 from Sikkim itself. As regards the name : WaUich's Begonias are greatly mixed : 

 even on the same sheets. The three sheets of No. 3686 at Kew are B. sQittata, 

 A. DC, but the type sheet of S. scutata No. 3686 in the Jjinnsean Society's Her- 

 barium is B. JosepM, A. DC, which is also mixed with B. picta in the sheet of 

 3683 A.
