MEMOIRS OF THE NEW YORK BOTANICAL GARDEN. I45 



A glandular-pubescent plant, low and caespitose, with the leaves 

 crowded at the summit, resembling somewhat the Asiatic A. dicho- 

 toma, but differing in the broadly ovate acute leaves, the obtuse 

 sepals and the longer narrow petals which are about twice as long as 

 the sepals. It resembles a Ccrasiiuin more than an AJsinc in gen- 

 eral habit. Among rocks, at an altitude of 3000 m. or more.
