species. Thus Geraniwm silvaticum, though occurring in Stafford- 
shire and West Yorkshire, and recorded in Top. Bot. for 
Derbyshire, may possibly be a case of confusion with G. pratense ; 
Sarifraga aizoides and Drosera longifolia, 1£ not errors, seem now 
extinct; Filago gallica appears to have been confused with 
F. minima; Gentiana Pneumonanthe is most probably extinct ; 
Mentha Pulegium, once found in several localities, seems to have 
died out in all; Rumer maritimus is not now to be found in its 
old habitat at Swarkeston, where Ray recorded it ; Cephalanthera 
pallens, recorded in Pilkington (Newton Wood) and Top. Bot., 
1883, is not now to be found; Osmunda regalis, in the only 
locality where it occurs at the present time, is an introduced 
plant. 
There are still some few plants which seem worth mentioning 
as likely to occur in the County, seeing that they occur in one or 
more of the surrounding five, but which have not as yet been 
discovered, and therefore should be looked for :— 
Chester. Leicester. Notts. Staffs. W. Yorks.
