SiKKm HiMAiATA, 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 Britrichmms 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 acheues are narrowly obovoid, 

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



72. ARTEDXXSXA, lAnn.
