plants as C. longifolia, Benth., var. cespitosa, C, B. Clarke ; which I now think 
a distinct species, i.e., C. cespitosa, Kotschy & Peyr., n. 10 below.—The var. 6 bake- 
riana, C. B. Clarke (in DC. Monogr. Phan. iii, 259), is more glabrous with larger 
leaves than in Bentham’s type; in Natt’s plant the leaves attain 12 by j in., and are 
glabrate. 
8. C. polyrrhiza, Hassk. Commel. Ind. 150. Moderately villous, 
becoming glabrate. Roots many, thick, long; on the crown of the 
roots (or shortened sterile stem) is the central tuft of leaves; these 
leaves 2 by }in., lanceolate. Lateral flowering stems 4—5, 3-5 in. long, 
frequently divided, with 3-5 heads of flowers, and smaller leaves ; outer- 
most bracts to the terminal heads } in. long, ovate; bracts of the 
cymes obscurely (or not conspicuously) 2-ranked.—Hassk. in Schweinf.

9. C. djurensis, C. B. Clarke in DC. Monogr. Phan. iii. 256. 
Young parts villous and with white wool, but the whole plant becomes 
nearly glabrate. Roots thick. Sterile central stem short; leaves on 
this attaining 10 by }in., linear. Lateral flowering stems 12-20 in. 
long, rather robust, with 2 or 3 heads of flowers and 2-0 leaves 
(besides the outermost bracts to these heads). Stem leaves attaining 
6 in. in length, linear. Heads of several clustered cymes, $—1 } in. broad ; 
outermost bracts to the terminal heads 2-3 in. long, linear. Bracts to 
a cymes distinctly 2-ranked.—Durand & Schinz, Conspect. Fl. Afr.

10. C. cespitosa, Kotschy & Peyr. Pl. Tinn. 48. Leaves and 
stems villous, becoming glabrate. Stems abrupt at the base, with 
slender wiry roots. Basal leaves tufted, up to 3 by 4 in., oblong-lanceo- 
late, usually persistently shaggy near the base beneath. Flowering 
stem 8—12 in. long, slender, erect, scapose, with 2—6 heads of flowers. 
Leaves on the flowering stem 1 or 0 (besides the floral leaves), reduced 
to sheaths with a leafy triangular point hardly } in. long. Flower- 
heads hardly } in. long, of 1 or few cymes, usually very oblique ; outer- 
most bracts 3-1 in. long, lanceolate, faleate; bracts in the cymes con- 
spicuously 2-ranked, hairy.—Schweinf. Beitr. FI. Aethiop. 299.
