On moist rocks in the Highlands of Scotland.

Perennial. July. 



Root somewhat woody, with many fibres. Sterns 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 ; the radical ones 

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

 dered footstalks, 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 as long as the seed-down ; limb the length of the tube, 

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

 vias 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. 



4. E. unijlorus. Pale-rayed Mountain Flea-bane. 



Stem single-flowered. Calyx woolly. Radius erect, twice

Perennial. July. 



This agrees in size with the smaller specimens of the last, with 

 which it closely accords likewise in every part of the herbage, 

 but I believe the stem very seldom, if ever, produces more than
