114 PARONYCHIACE^. 



VII. [Frequent in Hide Park ; Merrett, 5.] Bet. Kentish Town and Hamp- 



stead ; E. Cat. i. 17. Chelsea Common; Herb. Mus. Brit. South 



Heath, Hampstead. 



First record : Merrett, 1666. M. minor, G-m. is the more common variety 



in Middlesex ; but the large floating plant, M. rivularis, Gm. occiirs at 



(I.) Stanmore Heath, and probably in other places. 



Claytonia perfoliata, Bon. Syme E. B. ii. 260. VII. The late Mr. An- 

 derson introduced it into the Botanic Garden at Chelsea, where it soon 

 became a most troublesome weed, and remains so at the present day 

 (1853), coming up spontaneously by thousands in various parts of the 

 garden ; E. Newman in Phyt. iv. 983. Mr. T. Moore informs us 

 that it is still (1869) an abundant weed there.

 Dry fields and commons. P. ? July. 

 VI. In meadows at Colney Hatch ; Huds. i. 94. We found it in a field at 

 Finchley, and likewise at Colney Hatch ; M. Sf G. 455. Finchley 

 Common, 1795, Mr. Dickson; C. C. Bahington in E. B. 8. iii. 2857. 

 First record: Hudson, 11 &0; last, 1795. Likely to be refound. Mr. 

 Babington possesses a specimen of Dickson's Finchley Common plant, 

 marked H. hirsuta, of which he says, ' It is not that plant, being exactly 

 H. glabra^ {loc. cit.); and again, 'The Finchley Common plant was 

 H. glabra' {Bab. Man. vi. 136).] 



[251. ^B. birsuta, L. 



Cyb. Br. i. 389. E. B. t. 1379. 

 VI. ? Near Highgate; Dicks. H. S. fasc. 19 (published in 1802). 

 The specimen in the British Musevmi copy appears to be correctly named 

 H. kirsicta. It was probably an introduction at Highgate ; and, 

 though it has not since been met with in Middlesex, it has occurred at 

 Hartlepool, and is stated in Sg?ne E. B. vii. 183, to have 'recently 

 occurred near Coventry, no duubt accidentally introduced.' Mr. Syme 

 considers that this and H. glabra should be combined, each standing 

 as a sub-species, whilst H. ciliata is kept distinct ; and in L. Cat. 

 H. hirsuta is entered in italics as var. ^ of H. glabra.']
