the neighbourhood of Hull ; and the Pimpinella is a plant 

 veiy likely to gi'ow in a gi-ass field in Tiree or Tirey. In-

Native. Rupestral. Very local; occurring at Beny 

 Head, in Devon ; at Uphill and Worle Hill, in Somerset ; 

 also on St. Vincent's Rocks, on the Gloucestershire side of 

 the Avon, near Bristol. It is likewise reported fi-om Here-
