 VII. A common London plant. Chelsea. Green Park. Bedford Place. 

 Thames Embankment. Isle of Dogs. 



Pirst record : Doody, about 1700. Several -well-marked forms are included 

 here, as was long ago noticed by Buddie and Petiver, the former of 

 whom distinguished four, and inclined to ' think them different species ' ; 

 and the latter figured them as London plants in H. B. Cat. s. figs. 1-4. 

 Mr. Syme enumerates six sub-species, of which we have probably all 

 except P. Uttorale, Link. P. agrestinum, Jord., and P. milgatum, Syme, 

 are certainly common enough. P. arenastntm, Bor., ' common near 

 London,' occurs at Harefield, and by the towing-path at Hampton 

 Court ; and Mr. Newbould has seen it at Acton, &c. It is the Thickset 

 Knotgrass figured in Pet. H. B. Cat. x. fig. 2. P. viicrospemium, Jord., 

 we have not noticed. P. rurivagum, Jord., is probably (see Budd. 

 Herb, cxvii. fol. 22) the Narrow Knotgrass of Pet. H. B. Cat. x. fig. 4, 

 and the P. oblong, angustoque fd. C. B. P., found (VI.) amongst the corn 

 in Houndfield by Poundersend, plentifully ; Doody MSS. and Bill, in 

 B. 8y7i. iii. 146. It grows (V.) in cornfields on Horsington Hill.
