Begonia.~] LXVI. BEGONIACE*. (C. B. Clarke.) 641 



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

 -| in., lanceolate, sometimes fimbriate ; flowers not many, small, white tinged with 

 rose. MALE : 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, 

 each divided into two curved branches. Capsule 3 by in. including the wings, 

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

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

 Snc. 1877, pt. ii. 107) keeps B. parvuliflora "a caulescent wholly glabrous herb" 

 distinct from B. velutina " a scapigerous herb with leaves pilose above : " but A. 

 DC.'s type of B. parvuliflora (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 difference between the two is that in B. velutina the leaves are often 

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



17. B. g-emmipara, Hook. f. Itt. Him. PL t. 14 ; caulescent, leaved 

 incise-serrate or lobed, peduncles axillary short few-flowered, 2 large round per- 

 sistent bracts on each pedicel near the flower, seeds with adpressed papillae. 

 A. DC. Prodr. xv. pt. i. 314. 



SIKBIIM, alt. 6000-11,000 ft; plentiful round Darjeeling. 



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

 acuminate, 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. 

 Capsule \ by in. including the wings, somewhat inflated, with a medial line on each 

 face ; wings nearly equal, upper margins horizontal. In some of the axils the 

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

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

 parous bulbils. Alph. DC. gives dioecious as a character of his section Putzeysia, 

 but this, the only species of that section is, as all other Indian Begonias, monoecious 

 or occasionally dioecious. 



18. B. cordifolia, Thwaites Enum. 129 ; stemless, leaves orbicular-cor- 

 date crenate-serrate, capsule with 3 subequal not broad wings. A. DC. Prodr. 

 xv. pt. i. 328 ; B. Arnottiana, A. DC. I. c. 322. Diploclinium Arnottianum and 

 cordifolium, Wight Ic. t. 1815, 1816. 



South DECCAN PENINSULA ; Courtallum ; Wight. CEYLON ; Thwaites. 



Rootstock tuberous. Leaves l|-3 in. diam., rarely subacute, nearly equal at the 

 base, pilose above, laxly pubescent on the nerves beneath ; petiole 2-5 in., laxly 

 pubescent; stipules f in., ovate-lanceolate, glabrous. Scape 6 in., repeatedly 

 dichotomous ; flowers medium-sized, numerous ; bracts in., lanceolate. MALE : 

 sepals 2, round ; petals 2, smaller, narrow ; stamens numerous, shortly monadelphous, 

 anthers obovoid, connective not produced. FEMALE : perianth-segments 5-4- (3- in. 

 Wight's Icon 3-lobed) ; styles 3, nearly separate, divided half way up into two curved 

 branches. Capsule f by f in. including the wings, perianth deciduous, styles per- 

 sistent ; wings narrow, upper margin rounded or shortly horizontal, dehiscing on all 

 three faces. Seeds shortly ellipsoid. Wight finally united his D. Arnottianum with 

 his D. cordifolium. Alph. DC. separated them again on the sole ground that D. Arnot- 

 tianum had 4 segments to the female perianth, D. cordifolium only 3. But in Wight's 

 specimens of B. cordifolium all the female flowers examined have 5. The var. 

 insularis of A. DC. founded on Mr. Thwaites' No. 3584 has the leaves acute with 

 the nerves beneath more shaggy than in the type.
