19. C. angustifolia, Vahl, Synth. Bot. i. 29. Very nearly allied to 

 the preceding, the general description of which will apply, differing in 

 the narrower oval-lanceolate leaflets which are wholly glabrous or the 

 pubescence all but imperceptible, 1-2 in. long, and usually in 5 to 8 

 pairs, as well as in the narrower legumes which are usually 7-8 lines 

 in breadth. — Batka, Monog. Senna, t. ii. C. lanceolata, Wight et Arn.

20. C. Absus, Linn. ; DC. Prod. ii. 500. A glandular-pubescent 

 or pilose erect or ascending much-branched herb or undershrub, usually 

 from 1-2 (-4) ft. in height. Leaves with 2 pairs of leaflets ; common 

 petiole slender, 1^—3 in. long, patent-glandular-pilose throughout, 

 interpetiolular glands small or rudimentary ; leaflets membranous, 

 varying from obliquely ovate or obovate to elliptic-oblong, obtuse, finely 

 mucronate or sometimes broadly pointed, thinly pubescent or sub- 

 glabrous. Stipules subulate. Flowers rather small, yellow or red, in 

 short lax pilose or pubescent terminal or leaf-opposed racemes ; bracts 

 very small, persistent, ovate, often acuminate, shorter than the pedicels 

 of ^— I in. Sepals subequal, linear-lanceolate, rather obtuse. Petals 

 broadly oblanceolate to obovate, narrowed below. Stamens usually 

 4, 5 or 6, all perfect ; anthers linear-oblong, dehiscing from the mi- 

 nutely mucronate apex more or less longitudinally. Legume 2-valved, 

 linear, obliquely pointed at each end, 1^-2 in. long, J-^ in. broad; 

 valves slightly convex. Seeds 6-9, compressed oblique^ coty- 

 ledons plane, extending the length of the larger diameter of the 

 seed between layers of moderately thick albumen. — C. viscosa, Schum.
