Frequent in rocky mountainous situations in England, Scotland 

 and Ireland. 21. 5— 7. — An abundant and very variable plant! 



We hesitate vvhether to refer S. incurvifolia of Don here or to the 

 next, one cultivated specimen having the lobes of the leaves mucro- 

 nate, and another quite obtuse, yet not otherwise distinguishable. 



14. S. c<Bspit6sa L.? (tufted alpine S.) ; sterile shoots usually 



very short or wanting, root-leaves crowded fringed 3— 5-cleft 



with obtuse lobes lowermost sometimes undivided, caljx-seo-- 



ments obtuse, fruit hemispherical. — «. smaller, without sterile 



shoots. E. B. t. 794.—/?. larger. S. decipiens Ehrh. S

 ^- ^~''^' — We fear that the British species is only a variety of the 

 last with obtuse lobes to the leaves. In the Lapland, Norway, and 

 Arctic American plants (see Gunner Norv. ii. t. 7. f. 1, 3, 4, which is 

 also S. Grcenlandica L.) the calyx when in fruit is of a different form; 

 and the leaves, which are almost glabrous on the surface, are never 

 ciliated with short glandular hairs. 



15. S. *muscoides Wulf (mos,vj alpine S.) ; sterile shoots very 



short erect, radical leaves crowded linear obtuse entire and 



trihd, stem nearly naked few -flowered, petals oblong obtuse 



(butt-coloured) a little longer than the superior calyx. E. B.
