SIKKIM HIMALAYA, on the Tibetan frontier, alt. 16-18,000 ft., J. D. H. 



A. very singular species, forming dense cushions, at the highest elevation reached 

 by flowering plants in Sikkim, resembling one of the moss-like Eritrichiums in habit. 

 The short flowerless shoots have often silvery white silky pubescence, which contrasts 

 with the tawny wool of the flowering branches, which are club-shaped, the dense in- 

 florescence forming the broad end of the club. The achenes are narrowly obovoid, 

 with a lax pericarp and small cupular tip, and with the corollas are in. long. 



72. ARTEMISIA, Linn. 



Herbs or shrubs, usually strong-scented. Leaves alternate, entire serrate or

 tile, very slender, 2-3-toothed ; disk fl. g , fertile or sterile, limb 5-fid. Involucre 

 ovoid, subglobose or hemispheric; bracts few-seriate, outer shorter, margins 

 scarious ; receptacle flat or raised, naked or hirsute. Anther-bases obtuse, entire. 

 Style-arms of with truncate usually penicillate tips, often connate in the

 or paniculately branched, heads - in. long subsessile or pedicelled broadly

WESTERN TIBET, alt. 12-14,000 ft., from Rupchu(N. of Kumaon) westwards. Dis-

 or 0. Racemes copious. Heads shining ; flowers very few. Achenes 2-3, narrowly
