Occurs eastward to N. W. India. 
This species and O. acutifolia and ©. angustifolia afford officinal senna. 
17. C. holosericea, Fresen. in. Flora, 1839, 84. 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; }—1 in. 
long. Stipules subulate, spreading, somewhat rigid, 14~2 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—11 in. long, 6—7 lines broad; valves thinly chartaceous, pubes- 
cent, unappendaged.—Batka, Monog. Senna, t. iv. (Senna ovalifolia) ;

18. C. acutifolia, Delile, Flore d’ Egypte, 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 less 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 baly 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; 14-2} in. long, #-1 in. 
broad; valves chartaceous, obsoletely or thinly puberulous, faintly 
transversely veined, unappendaged. Seeds shavebeeceee com- 
pressed ; cotyledons plane, extending the larger diameter of the seed 
in transverse section.—Batka, Monog. Senna, t. i. For synonymy see

I follow Batka in adopting Delile’s specific name for this plant. Those of prior date 
appear to be vitiated either by confusion of different species or citation of conflicting
