122 ENGLISH BOTANY. 



also found in 1841 near Ware Mill, Herefordshire, probably introduced 

 witli flax. In 1864 I saw several plant^of it on the shingle round 

 Sandown Mill at Deal, but doubtless it had been introduced with foreign 

 grain. It has, I believe, also occurred near Paisley, but does not 

 become permanently naturalised in this countiy.

In 1846 this species was gathered under a hedge at Charlton 

 House, ne.ar Alton, in Hampshire.
