small, lanceolate. Peduncles 4-10 in., nearly glabrous, laxly dichotomous ; bracts 

 J-i in., lapceolate, sometimes fimbriate ; flowers not many, small, white tinged with 

 rose. MIle : sepals 2, broad- elliptic, glabrous or with a few scattered hairs ; petals 2, 

 narrowly oblong; stamens about 25, monadelphous, anthers obovoid, connective not 

 produced. Female: perianth of 5 or 4 segments; styles 3, somewhat combined, 

 «ach divided into two curved branches. Capsule ^ by i in. including the wings, 

 one wing veiy long, margins of all extended horizontally from the summit of the 

 capsule, dehiscing on all three faces. Seeds short-ellipsoid.— Kurz (in Journ. As. 

 Soc, lS77y pt. ii. 107) keeps B. parvuliflora "a caulescent wholly glabrous herb" 

 distinct from B. velutina ^' ^ scapigerous herb with leaves pilose above:" but A, 

 -DC/s type of B, parv^uliflora (marked by him B. Lobbiana) has the leaves decidedly 

 pilose above and the stems not more caulescent than some of Parish's B. velutina. 

 The only diflference between the two is that in B, velutina the leaves are often 

 beautifully variegated and doubly serrated; but not always Parish's specimens. ;

Bootstock tuberous. Stem 6-16 in,, succulent, glabrous. Leaves ovate-cordate, 

 ^^Tipunate, often with acute or lanceolate lobes, glabrous beneath, often pilose above ; 

 petiole 1-3 in.; stipules ovate. Peduncles short, axillary, little divided, pedicels 

 longer ; flowers pendulous, medium-sized, white or with rose stripes, usually mo- 

 noecious. Male : sepals 2 ; petals 2, narrower ; stamens numerous, shortly mona- 

 delphous, anthers obovoid, connective not produced. Female : perianth-segments 5, 

 nearly equal, persistent ; styles 3, nearly distinct, broader upwards, stigmas lunate. 

 ^dpsvle ^ by ^ in. including the wings, somewhat inflated, with a medial line on each 

 ^e; wiujgs nearly equal, upper margins horizontal. — In some of the axils the 

 PWuncIe instead of producing flowers is very shortly once or twice divided, each 

 branch terminating in 4 quadrangular cups, each packed closely with oblong vivi- 

 P^us bulbils. Alph. DC- gives dioecious as a character of his section Putzeysia^ 

 "^t this, the only species of that section is, as all other Indian Begonias, monoecious 

 or occasionally dioecious.
