Cassia.] XLVII. § CiESALPINIE^E (OLIVER). 275 



Tropics both in Asia and America, though probably only truly native in the latter. It 

 is likely to turn up in Tropical Africa as an introduced or perhaps naturalized species. 



11.* C. laevigata, Willd.-; Walp. Rep. i. 816. A glabrous shrub, 

 with terete green erect branches, attaining 6-10 ft. ; leaflets in 3-4 

 pairs, membranous, the upper larger, varying from ovate-oblong to 

 lanceolate, finely acuminate, the larger from 2J-4 in. in length ; petio- 

 lules 1 line ; common petiole 4-5 in., channelled, glabrous, with 

 oblong or cylindrical interpetiolular glands ; basal gland 0. Stipules 

 linear deciduous. Flowers glabrous, similar to those of C. occidentalism 

 in pedunculate axillary corymbose erect racemes, much shorter than 

 the leaves. Bracts caducous. Legumes erect, thinly coriaceous or 

 chartaceous, terete, smooth, glabrous, obtuse, apiculate, 3-3 \ in. long, 

 about J in. in diameter, tardily dehiscent in 2 valves. Seeds horizontal, 

 shining. Embryo as in C. occidentalis. — Collad. Hist. Cass. t. 5. 



Upper Guinea. Sierra Leone, T. Vogel! Fernando Po, T. Vogel! Mann! 

 A Tropical American species, probably not indigenous in Africa. It is recorded from 

 Australia, but doubtfully native there according to Mr. Bentham. 



12. C. Tora, Linn.; Walp. Rep. i. 817. Stem annual, erect or 

 ascending, terete or nearly so, glabrous or thinly pilose or pubescent, 

 attaining 2-3 ft. Leaflets in 2 or 3 pairs, obovate or obovate-oblong, 

 obtuse, mucronate, thinly subappressed-pilose or glabrous, varying 

 from |-1J or 2 in. in length ; petiolules very short. Common petiole 

 pubescent or nearly glabrous, with conspicuous narrow-cylindrical 

 glands between at least the lower pinnae. Stipules subulate, or nar- 

 row-linear. Flowers usually in pairs or solitary, axillary, with or without 

 a short common peduncle ; pedicels f-1 in. long, in fruit stout ascend- 

 ing. Sepals unequal, obtuse. Petals obovate, shortly clawed. Anterior 

 anthers enlarged and usually distinctly obtusely produced at the apex. 

 Legumes elongate, curved, narrow-linear, 4-8 in. long, \-\ in. broad, 

 oblong-quadrate in section ; valves separating, marked internally with 

 the oblique transverse partial septa. Seeds arranged lengthwise, their 

 larger diameter parallel with the valves, rhomboidal or obliquely ob- 

 long; cotyledons plicate in transverse section. — C. obtusifolia, Linn., 

 Walp. Rep. I.e. Chammfistula contorta, Don. Gen. Syst. ii. 452. Cassia 

 contorta, Vog., Walp. Rep. i. 816. 



Widely diffused in Tropical Africa, as indeed through the Tropics generally. Accord- 

 ing to T. Vogel the stem occasionally becomes arborescent in Guinea. 



13. *C. alata, Linn.; DC. Prod. ii. 492. An erect glabrous or sub- 

 glabrous shrub of 3—8 ft. ; stem terete, smooth, glabrous, or minutely 

 puberulous. Leaves from 1—2 or 3 ft. in length, rachis acutely mar- 

 gined above when dry, glandular with a prominent transverse ridge con- 

 necting the opposite leaflets ; leaflets in 9-12 pairs, very broadly oblong 

 elliptic-oblong or, the upper larger leaflets obovate-elliptical, rounded 

 above and very obtuse or retuse, mucronate, base oblique truncate or 

 subcordate at least as to the lower margin, glabrous, firmly membranous ; 

 the larger leaflets varying from 3-7 in. in length, subsessile or petio- 

 lules 1 line. Stipules obliquely triangular, acute, broad-based, persis-
