The species cultivated arc: 1. C. arboresccns, Common Bladder 

 Senna; 2. C. cruenta, Oriental Bladder Senna; 3. C. Pocockii, Po- 

 cock's Bladder Senna; 4. C. frutescem, Scarlet Bladder Senna. 



The first has several woody stems, which grow to the height of 

 twelve or fourteen feet, sending out many woody branches, with 

 winged leaves, composed of four or five pairs of oval lobes, placed 

 opposite, terminated by an odd one; these are indented at the top 

 in form of a heart, and are of a grayish colour. The flowers come 

 out from the wings of the leaves upon slender peduncles about two 

 inches long, each sustaining two or three yellow flowers, whose stand- 

 ard is reflexed and large, with a dark-coloured mark on it. Native 

 of the South of France, c. 



The second species has a woody stem, which sends out many 

 branches on every side, which do not rise above seven or eight feet 

 high; these are not so strong as those of the first sort, and the leaves 

 are composed of five or six pairs of small heart-shaped leaflets, ter- 

 minated by an odd one. The flowers proceed from the side of the 

 branches, standing upon peduncles, each sustaining two or three 

 flowers, shaped like those of the first sort, but smaller; they are of a 

 dark red colour, marked with yellow, appearing in June, the seeds 

 ripening in autumn. It was found in the Levant. 



The third is a shrub which seldom grows more than six or seven 

 feet high in this country. The branches are very slender, and much 

 more pliant than those of the common sort, and therefore it grows 

 less erect. The leaves are composed of nine pairs of leaflets, and 

 arc much smaller. The flowers are of a. brighter yellow, appear a 

 .month earlier than in the common sort, and there is a succession of 

 them till late in the autumn, which renders it much more valuable; 

 and the branches not shooting so luxuriantly nor so upright, it is in 

 less danger of being broken by strong winds in summer. It is a na- 

 tive of the Levant. 



The fourth species is a hoary shrub, with tomentose leaflets, 

 smooth on the upper surface. It rises from two to four feet in height 

 in favourable seasons, and in a warm situation; plants of three years 

 standing will sometimes be six feet high. The stem is weak, the
