 London plant). 

 On walls and dry waste ground ; very rare. A. or "B. July, August. 

 VII. Almost everywhere in the suburbs of London ; Merrett, 66. Espe- 

 cially on earth mounds bet. the City and Kensington; in 1667 and 

 1668, after the City was burnt, it grew very abundantly on the ruins 

 round St. Paul's ; S. Cat. i. 104. Copiously about Chelsea ; Mori- 

 son, 2, 219 ; where, and also in the Prtsludia of the same author, 

 p. 498, is an interesting account of the growth of this species after 

 the great fire. Plentifully on the Lord Cheney's wall at Chelsea ; 

 Pet. Midd. Bet. Brick Lane and Islington ; Pet. Bot. Lond. 291. 

 At the end of Goswell Street ; Hill, 338. Frequent enough about 

 London ; Curt. F. L. In Chelsea Garden and all that neighbour- 

 hood a troublesome weed; E. B. 1631. Brompton, Mr. Borrer ; 

 about Haggerstone, and near Chelsea, E. Forster ; opposite Shore- 

 ditch Workhouse, L. "W. Dillwyn ; B. G. 408. Growing in ] 832 

 beneath brick walls by the side of a then new road leading from 

 Earl's Court to the new church near Walham Green, which road 

 passes the north boundary of the cemetery, not very plentifully. . . . 

 Mr. Haworth told me that when he first came to live at Chelsea, 

 about 1790-95, it used to grow in great abundance in various places 

 by the roadside bet. Little Chelsea and Hyde Park Comer; 

 Pamplin {v. s.). See also New B. G. 97. 

 First record: Merrett, before 1666 ; also the first notice as British. We 

 have seen no specimens collected since 1832, nor ever met with it our- 

 selves, though, no doubt, it was formerly very abundant, as the above 

 localities are confirmed by specimens in all the older herbaria col- 

 lected near London.] 



[49. * S. Sopbia, L. Flixweed. 



Sophia chirurgoruin (Morison). Nasturtium sylv. tenuissime divisum, 



C. B. P. (Blackst.).

 had died of the plague) not far from S. James's Palace, close to 

 Barkshire House, in vast quantity ; Morison, 2, 219. 

 First record : Morison, 1680. No modern authority. A scarce plant 

 round London ; it is said to have grown in Battersea Fields, Surrey, 

 some twenty years back, but has not recently been seen there. 

 Morison considers that this and similar weeds arise spontaneously 

 without seed ; see also the Praludia of the same author.]
