Native. Uliginal. Carex ii-rigua may possibly be a 

 true species ; but, if so, its stations cannot at present be 

 satisfactorily extricated from those of C. limosa. It can- 

 not be said that the county of Somerset is a very improba- 

 ble one for C. limosa ; but being the only county reported 

 for this species, in the most southerly provinces, and rest- 

 ing only on bad authority (that of Mr. Swayne, in Bot. 

 Guide), it is excluded. The county of Worcester is ques- 

 tioned, because the locality " Wichbury Hill, near Stour- 

 bridge," is given for Worcestershire by Mr Lees, and for 

 Staffordshire by Dr. Garner. C. irrigua is said to have 

 been found in Northumberland, Dumfries, Ku'kcudbright, 

 Ayr, and Dumbarton. The upper limit of neither species 

 or variety has been correctly ascertained.
