Perennial. July. 



Root somewhat woody, with many fibres. Stems from 4 to 6 inches 

 high ; sometimes, on the Alps of Switzerland, taller, with 3 or 

 more flowers -, but on the Scottish mountains mostly simple 

 and single-flowered, leafy, striated, most hairy in the upper 

 part, frequently purplish. Leaves scattered, sessile, lanceolate, 

 dilated at the base, entire, hairy on both sides 3 the radical ones 

 numerous, more obovate, and larger, tapering down into bor- 

 dered /oofs^aZA-s, like the foregoing. Fl. twice the size of that 

 species, generally solitary, erect, on a naked stalk. Cal. more 

 or less hairy, sometimes as much so as in the following. Florets 

 of the disk yellow ; those of the radius numerous, light purple ; 

 the tube us long as the seed-down 3 limb the length of the tube, 

 ligulate, narrow, spreading, very slightly curved upward. Stig- 

 mas of these florets more slender than those in the disk. Seeds 

 of all the florets hairy, to all appearance perfect, but no experi- 

 ments have been made to ascertain this point.
