On alpine rocks and precipices. 



On the vvest side of the summit of Ingleborough hill, Yorkshire. 

 Dr. Richardson. On Snowdon plentifully. Mr. Llwyd. On Ben 

 Lomond and other Scottish mountains, frequent. 



Perennial. April. 



Stems numerous, prostrate, or pendulous, with many opposite, 

 reddish, densely leafy, branches, forming broad dense tufts. 

 Leaves small, imbricated in 4 rows, dark green, ovate, obtuse, 

 slightly stalked, smooth, except a strong marginal fringe ; 

 some of the uppermost abrupt at the point, and marked with 

 1 or 2 perforations 3 those on the young trailing shoots more 

 distant, and opposite only. Flowers terminal, solitary, nearly 

 sessile, large, handsome. Cal. half inferior, with broad, deep, 

 obtuse, fleshy, spreading, fringed segments. Pet. obovate, 

 5 -ribbed, crimson with more or less of a blue tint. Stayn. erect, 

 awl-shaped, for the most part shorter than the corolla. Styles 

 short and thick, with capitate downy stigmas. Caps, surrounded 

 in its lower half by the entire base of the calyx, with which it is 

 closely incorporated, the u])per portion sejiarating into 2 spread- 

 ing valves, tipped with the straight styles. 



The present species, with one, or perhaps two, exotic ones, di- 

 stinguished by their opposite leaves, differ greatly in habit from 

 the rest of the genus, and indeed from others of this section, 

 so that it is difficult to arrange them according to any natural 

 affinity. The same may be said of the next.
