plants as C. lonrjifoHa, Benth,, var. ccespitosa, C. B. Clarke ; which I now think 

 a distinct species, i.e., C. caspitosa, Kotschy & Peyr., n. 10 below. — The var. /3 hake- 

 riana, C. B. Clarke (in DC. Monogr. Phan. iii, 259), is more glabrous with larger 

 leaves than in lientham's type ; in Nutt's plant the leaves attain 12 by \ in., and are 

 glabrate. 



8. C. polyrrhiza, JIassk. Commel. Ind. loU. 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 l)y l in., lanceolate. Lateral flowering stems 4-"), :3-5 in. long, 

 frequently divided, with ;>-5 heads of flowers, and smaller leaves ; outer- 

 most bracts to the terminal heads J 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 J in., linear. Lateral flowering stems 12-20 in. 

 long, rather robust, with 2 or ?> 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, J-l | in. broad ; 

 outermost bracts to the terminal heads 2-3 in. long, linear. Bracts to 

 the cymes distinctly 2-ranked. — Durand &, Schinz, Conspect. Fl. Afr.

10. C. caespitosa, Kotschy ct- Peyr. PL Tinn. 48. Leaves and 

 stems villous, becoming glabi-ate. Stems abrupt at the base, with 

 slender wiry roots. Basal leaves tufted, up to 3 by J in., oblong-lanceo- 

 late, usually persistently shaggy near the base beneath. Floweiing 

 stem 8—12 in. long, slender, erect, scapose, with 2-^ heads of flowers. 

 Leaves on the flowering stem 1 or (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 J-1 in. long, lanceolate, falcate ; bracts in the cymes con- 

 spicuously 2-ranked, hairy. — Schweinf. Beitr. Fl. Aethiop. 295.
