5 This species is very nearly related to C. serrata, Presl, with which it has been 
identified by Baillon. It may usually be recognised by its generally narrower 
leaves and its always unequal male petals, but in some gatherings of both species 
now one, now the other character breaks down. The only differential character 
which appears to be constant is to be met with in the female calyx, which is 6-lobed 
in C. senegalensis, more than 6-lobed in C. serrata. 
6. C. serrata, Presl, Epimel. Bot. 213. An annual herb; stems 
branching, rather slender, hispid upwards, 14-3 ft. high. Leaves short- 
petioled, lanceolate or narrow-lanceolate, acute, margin sharply and often 
rather closely serrate, narrowed to the base or cuneate, 2-4 in. long, 
3-4 in. wide, pale green, glabrous on both surfaces or with a few hairs 
on the nerves beneath; main nerves 10-12 on each side, rather promi- 
nent beneath ; petiole 4-4 in. long, glabrous ; stipules linear, glabrous, 
caducous. Racemes 2-4 in. long; rhachis and pedicels glabrous or 
Sparingly pubescent; bracts ovate-lanceolate, small. Male sepals 5, 
ovate-triangular, acute, pubescent. Petals 5, subspathulate-oblong, 
clawed, nearly equal, as long as the sepals, occasionally 2 distinctly smaller 
than the others. Stamens 10; filaments short. Female sepals 8-10, 
ovate-triangular, unequal, 4—5 inner rather larger than the 4-5 outer. 
etals 5, oblong-lanceolate, clawed, rather shorter than the inner sepals. 
Ovary closely beset with flattened eglandular processes. Capsule slightly 
muricate, 4 in. wide; accrescent sepals j,-{ in. long. Seeds usually 
Pale yellow or tawny, sometimes nearly black, oblong-globose.—Miill.
