Meadows ; very rare. P. August. 

 III. In considerable plenty in a grassy meadow close to the railway station 

 at Twickenham. 



V. A stray plant or two at Acton, doubtless introduced ; Newb. 



First record: Newboidd, about 1862. The Twickenham plant is 

 thoroughly established, and has the appearance of a native. It is, 

 however, most likely the remains of a garden, a supposition suggested 

 ])y the presence of horse-radish in the same field, and a garden rose 

 and periwinkles in a neighbouring hedge. Two forms grow together 

 here, the vars. a genuina and /B vulgaris of Koch's Synopsis Fl. Germ. 

 (the former is C. cuctdligera, Keich.). According to Syme E. B. v. 

 31, the Acton plant seems to belong to the continental form C. amara, 

 DC. ( = C serotina, Boreau).
