Native. Paludal, &c. Rather variable in situation for 

 so local a plant; apparently most affecting salt marshes 

 and the vicinity of the coast ; but occurring also in fields 

 and on commons more inland. Possibly the estimate of 20

 cies being recorded from 14 counties in the Nevt^ Guide.

Range of mean annual temperatvu-e 52 or 51. 



Native. Rupestral ? " On rocks at Torquay," " on the

 the contrary ?
