Native. Rupestral. Appai-ently limited to the peninsu- 

 la of Glamorganshii-e, which stretches westward from Swan- 

 sea. The stations ai-e reported at eight miles (Pennai'd 

 Castle rocks), and sixteen miles (Wonnshead) distant from 

 Swansea. It seems singular to find this Alpine and Pyi-e- 

 nean species thus isolatedly located on the coast of Wales. 

 Those who have visited the spot, appear to acknowledge 

 the stations as truly native. I am unable to speak to this 

 from my own observation ; South Wales being as yet an 

 un\asited province.
