Srxxim Himaraya; Yakla and Jongri, alt. 13-16,500 ft., Atkinson, Clarke. 
A stron ly scented herb. oot as thick as the thumb, short, fusiform, apparently 
fleshy within. . Stem 6-12 in., solitary, rarely 2 from the root, stout, erect, leafy, ter- 
minating in a single head. Leaves radical, 4-6 in. long, petioled, the primary segments 
rather distant, ovate or rounded, alternate acute, cauline sessile. Heads on the 
thickened woolly top of the stem; ligules not longer than the involucre; receptacle 
convex. Achenes } in. long, narrowly obconic, pale, top crenulate, pericarp lax.— This 
plant very closely resembles specimens of Tanacetum longifolium with solitary large 
heads, but is distinguished by the root, the absence of shining radical petioles, and by 
the presence of the ray. 
EXCLUDED SPECIES. 
C. Grirrirun, Clarke Comp. Ind. 148, is an Affrhan plant. It is very near C. 
Steliczkai, and may be a form of that species.
