with transverse partitions, protuberant at the seeds, scarcely pulpy within. 
Seeds compressed, vertical (i. e. the flat side parallel with the valves of the 
legume), almost obcordate, much shorter than the breadth of the legume.— 
Flowers in axillary racemes or terminal panicles. 
891. (7) C. obtusa (Roxb.:) perennial, herbaceous, diffuse, procumbent, 
branches glabrous: leaflets 4—6 pair, obtuse, mucronate, unequal at the base, 
glabrous: petioles and rachis without glands: stipules lanceolate-subulate, 
tapering, spreading, persistent : racemes axillary, few-flowered, much short- 
er than the leaves: pedicels without bracteas, legumes lunate, broad, thin, 
obtuse; valves protuberant and slightly angled but scarcely crested at the 
seeds.— Roxb. hort. Bengh. p. 31; in E. I. C. mus. tab. 1418 ; Wight! cat. n.

_ The Egyptian C. Senna (C. obovata, Coll.), of which there is a specimen in 
the Linnzan herbarium, is so very closely allied that we have some doubts 
of its being really distinct: it is, however, a diffuse shrubby plant ; the ra- 
cemes bear a considerable number of flowers, they are as long as the leaves, 
and when in fruit even longer than them, and the legumes are always, so far 
as we have seen, furnished with a little wing or crest on the valves at the 
protuberances caused by the seeds. To C. obovata, Collad., belongs C. Sen- 
na, «, Burm. Ind. p. 96. t. 33. f. 2, C. Senna of Swartz (now naturalized and 
very abundant near the sea-beach at Port-Royal in Jamaica), and C. Portu- 
regalis of Bancroft. 
892. (8) C. lanceolata (Forsk.:) suffruticose, erect, glabrous: leaflets 4-8 
pair, lanceolate, acute, nearly equal-sided : petioles and rachis without 
glands: stipules minute, acute, spreading or deflexed: racemes axillary, 
long-peduncled, many-flowered ; pedicels without bracteas: legumes flat, 
.. oblong-linear, broad, slightly lunate, obtuse, very slightly tumid at the seeds.

Perhaps only a naturalized plant, but Roxburgh states it to be a native of 
the interior of India. 
§ 5. Chameesenna, DC.—Sepals obtuse. Anthers 2-pored. Legumes more or 
less compressed, rarely somewhat cylindrical, with the sutures tumid, many- 
celled with complete or incomplete partitions, without pulp. Seeds vertical, 
ovate or 4-cornered, about as long as the breadth of the legume : podosperms 
shorter than the seed.—Flowers usually racemose. 
+ Shrubby or arboreous. 
a. Petioles and rachis without glands: legumes straight, many-seeded, compressed, taper- 
ing to a spear-shaped point: valves when ripe somewhat woody. 
7893. (9) C. florida (Vahl:) arboreous: leaflets 4-14 pair, elliptic, obtuse 
at both ends, somewhat emarginate, with a bristle-point, glabrous, shinmng: — | 
petiole and rachis without glands: stipules minute, subulate, caducous : pa- 
nicles terminating every branch, very large, many-flowered ; peduncles dense- 
ly pubescent: flowers long-pedicelled, corymbose toward the ends of the pe- 
duncles ; pedicels subtended by an oblong-lanceolate concave long-point 
tea: upper petal obcordate: legumes long, drooping, then straight, at- 
tenuated at both ends, pubescent ; sutures callous, thickened.—Vahl, symb. 3.
