leading from Earl's Court to the new church near Walham Green, which road 
worth told me that Mah p first came to live at Chelsea, about 1790-95, it used 
to grow in great abundance in various places by the roadside between Little

First record, Merrett, before 1666; also the first record as British. We 
have seen no specimens coliected since 1832, nor ever met with it ourselves, 
though no doubt it was formerly very abundant, as the above localities are con- 
by specimens in all the older herbaria collected near London. [P. 33.] 
The total number of native and naturalized species claimed by our 
authors for the county is 859, out of which 58 are supposed to be now 
extinct, and 133 are very rare. Besides these, they mention 120 
casual introductions and garden escapes. Adapting the species limits 
to those employed by Mr. Watson in * Cybele Britannica, and com- 
paring the county list with that for Britain as a whole, we obtain the 
following results, and we give also the North Yorkshire table for com- 
parison :—
