656 LXVI. BEGONIACE^. (C. B. Clarke.) [Begonia. 



VAB. 3. malabarica; leaves glabrous, capsules large slightly subquadral rather 

 than elliptic. As to Bheede Hort. Mai. ix. t. 86 referred here, it may be the present 

 plant as it is difficult to guess what other species Kheede could have got in Malabar : 

 though it differs not merely in the points mentioned by Alph. DC. ; but in the male 

 flowers with two sepals and two petals. 



DOUBTFUL AND EXCLUDED SPECIES. 



""65^. KHASIANA, C. B. Clarke ; flowers minute, capsule less than % in. B. pe- 

 dunculosa Wall. Cat. 3672 B. 



SYLHET MTS. (which means Khasia) ; WoMich. 



Branches weak, succulent, scariose winged, repeatedly divided with many leaves. 

 Leaves l-2 in., cordate, acute, very unequal at the base, serrate, pilose above, laxly 

 sparsely villose on the nerves beneath ; petiole ^-f in. ; stipules \ in., persistent, ob- 

 long, acute, glabrous. Peduncles from the lower as well &s from the upper axils, 

 l-l in., few-flowered ; bracts minute, elliptic, acute, ciliate, fimbriate. MALE : 

 sepals 2, scarcely in., round, glabrous ; petals ; stamens about 8, anthers oblong, 

 connective not produced. FEMALE: perianth of 5 segments; styles 3, divided up- 

 wards. Capsule 5 by ^ in. including the wings ; wings 3, one about twice as broad a* 

 the others, its margin from the top of the capsule first horizontal then rounding 

 away without angles ; capsule dehiscing by marginal lines within the margins of its_ 

 faces ; placentas not seen. 



B. TENUIFOLIA, Dryand. in Trans. Linn. Soc. i. 162, from Pulo Pontapgh, is not 

 a Pulo Pinang plant as A. DC. suspects from the similarity of the names (see Prodr. 

 xv. pt. i. 351). 



OKDEB LXVII. DATISCACEJE. (By 0. B. Clarke.) 



Trees or herbs. Leaves petioled, simple or pinnate ; stipules 0. Flowers 

 small, dioecious in the Indian species, clustered racenied or panicled. MALE : 

 calyx-tube short, teeth 3-9; petals 0; stamens 4-25. FEMALE: calyx-tube 

 adnate to the ovary, lobes 3-8 short ; petals ; ovary 1-celled, open or closed at 

 the vertex ; styles lateral, alternating with as many parietal placentae, simple or 

 2-partite ; ovules very many, ascending or horizontal. Capsule coriaceous or 

 membranous, opening at the vertex between the styles. Seeds very manv, small, 

 albuminous ; embryo straight, radicle next the hilum. DISTRIB. Species 4 ; 

 natives of the Mediterranean, Central Asia, Java, and North- West America.

Tall glabrous erect herbs. Leaves 3-partite or unequally pinnate, the upper- 

 most undivided ; leaflets lanceolate, strongly serrate. Flowers dioecious, axillary, 

 clustered, short-pedicelled. MALE : Calyx-tube very short, lobes 4-9, unequal ;
