 Occurs eastward to N. W. India. 

 This species and C. acutifolia and C. angustifolia afford officinal senna. 



17. C. holosericea, Fresen. in. Flora, 1839, 34. Shrubby; entire, 

 plant usually clothed with a very short rather dense or subvelvety 

 pubescence. Branches ascending, terete, striate. Leaves 5-8-jugate, 

 common petiole eglandular or glands rudimentary ; leaflets broadly ob- 

 long or ovate- oblong, obtuse entire or retuse mucronulate, closely 

 velvety-pubescent above and below, very shortly petiolulate; J— 1 in. 

 long. Stipules subulate, spreading, somewhat rigid, 1J— 2 lines long. 

 Racemes erect, falling short of the leaves. Flowers apparently as in 

 C. obtusifolia and C' acutifolia. Legumes flat, broadly falcate-oblong, 

 rounded at the extremity with an oblique mucro indicating the style- 

 base ; 1-1 \ in. long, 6-7 lines broad ; valves thinly chartaceous, pubes- 

 cent, unappendaged. — Batka, Monog. Senna, t. iv. (Senna ovalifolia) ;

18. C. acutifolia, Delile, Flore oVEgypte, 75, t. 27, fig. 1. Shrub or 

 undershrub with pale subterete or obtusely angled erect or ascending 

 branches, occasionally slightly zigzag above, glabrous at least below. 

 Leaves usually 4— 5-jugate (3—7), common petiole eglandular, puberu- 

 lous or glabrate ; leaflets oval or lanceolate, acute, mucronate, usually 

 more or le^ss distinctly puberulous or at length glabrous, pale or sub- 

 glaucous at least beneath, subsessile. Stipules subulate, spreading or 

 reflexed, 1—2 lines long. Racemes axillary, erect, rather laxly many- 

 flowered, usually considerably exceeding the subtending leaf. Bracts 

 membranous, ovate or obovate, caducous. Pedicels at length 2-3 lines. 

 Sepals obtuse, membranous. Two of the anterior anthers much ex- 

 ceeding the rest of the fertile stamens. Legume flat, very broadly 

 oblong, but slightly curved upwards, obliquely stipitate, broadly 

 rounded at the extremity with a minute or obsolete mucro indicating 

 the position of the style on the upper edge ; 1J— 2\ in. long, f-1 in. 

 broad; valves chartaceous, obsoletely or thinly puberulous, faintly 

 transversely veined, unappendaged. Seeds obovate-cuneate, com- 

 pressed ; cotyledons plane, extending the larger diameter of the seed 

 in transverse section. — Batka, Monog. Senna, t. i. For synonymy see

Occurs also in Africa, north of the Tropic. 



I follow Batka in adopting Delile'e specific name for this plant. Those of prior date 

 appear to be vitiated either by confusion of different species or citation of conflicting
