to the coast level. Its occurrence in Warwickshire, a 

 county of trifling elevation, shows that it will descend 

 quite low in the middle of England ; and its former loca- 

 lity in Sussex, I should suppose, may not have exceeded 

 100 or 150 yards.

Native. Littoral. A rare plant, which appears to be- 

 come more scarce than formerly. The only counties in 

 which I find localities recorded, are those named above 

 for the southern and northern limits of the species in Eng- 

 land. From the situations in which it grows, on dry and 

 shifting sands of the coast, its particular localities are 

 likely to be uncertain and variable, which may partly ex- 

 plain the unsuccessful search occasionally made for the 

 plant in its reported localities.
