 — S. oppositifolia. On Cwm Idwal near Twll Du. — S. caespitosa. Three 

 varieties, at least, of this very changeable plant occur in North Wales. 

 Near Twll Du its common appearance is that of the Lady's Cushion of the 

 gardens ; but in this state it has not been figured in the Eng. BoL, though 

 S. hirta, t. 2291. of that woi'k, comes nearest to it. The segments of the 

 leaves are narrow, and it is but slightly hairy. Under this appearance it is 

 S. caespitosa of the Swedish botanists. On Cwm Idwal near Twll Du it is 

 plentiful. S. caespitosa var. greenlandica, Eng. Bot. t. 794., the dwarf 

 broad-leaved variety is met with occasionally on the same mountain ; and S. 

 palmata, Eng, Bot. t. 455., S. decipiens, Sternberg, t. 23., the large broad- 

 leaved variety grows on the Peak of Snowden. The two latter are described 

 in Sniiith's English Flora as S. caespitosa a. and /3. — S. tridactylites. On 

 walls near Beaumaris and the Little Orms Head.
