120 FLORA OP THE BRISTOL COAL-FIELD. 



soem to render it impossible to draw a line of 

 demarcation between it and tlio common form. 

 The leaves of our plant are soft and flat, not 

 undulated, amplcxicaul, nor at all deourrcnt ; the 

 sinuations shallow and beautifully spinous-ciliate, 

 with spines so weak that the leaves can bo handled 

 with impunity. Lower petioles elongate. Ai\- 

 thodcs long-stalked, in a long lax panicle. 



Anthemis arvensis, L. 



In fair quantity on a heap of old colliery rubbish neai' 

 Kingswood, West Gloucestershire, where it has 

 been introduced by means unknown, but now seems 

 well established. The apparent absence of this 

 species from the area of the Bristol Coal-field has 

 not escaped notice, and is a peculiar circumstance. 

 Although somewhat rare, the plant is widely dis- 

 tributed in England, and in some of the westex'u 

 counties occurs frequently among clover and sown 

 grasses, as well as on the boi'ders of cultivated 

 fields. 



Mentha rotundifolia, L. 



A correction. In the " Flora," p. 136, it is mentioiuid 

 that a few plants of M. sylvestris were found by a 

 roadside at Portbury. Tliose were I'eally M. ro- 

 tundifolia, shown by I'ccent observation to gr-ow 

 there in some quantity. 



Mentha sylvestris, L., in Gloucestershire. 



A good patch on the bsmk o£ Avon, near Hanham. 



In Somerset, Mr. Fry reports a fresh locality by tlic 

 Chow, near Publow; wo have seen the plant also, 

 in greater abundance, lower down the sti-eam, at 

 intervals, for a considerable distance.
