COMPOSITE. 205 



anthodes in the fresh plant. Noticed again in the spring of 

 1876. Specimens more or less rayed were sent by the Rev. A. 

 Ley to the Botanical Exchange Club in 1876, gathered in May 

 of that year from two other stations, a couple of miles apart, 

 above the shore of Whitsand Bay. (See Bot. Ex. Club Rejy. 

 1876, 22.) 

 Mr. Watson observes in a letter to me : '"I think Dr. Boswell would 

 more rightly have named the Cork Groundsel as S. crassifoUus, Willd., 

 unless he deems S. vemalis, W. and K. , a special form of crassifoHus, 

 which he does not say. The ray is longer than in radiate vulgaris, 

 horizontal at first, and becomes revolute in the older (fertilized i) heads. 

 Here (Thames Ditton) it is quite hardy, and would become as trouble- 

 some a weed as >S'. vulgaris if allowed to seed freely." (June 7th, 1878.)
