thus ai)i)ear to be E. latifolium. For tlie other 15 pro- 

 vinces mentioned, there is good or admissible authority, 

 either in j)rint, or given to me in shape of manuscript 

 notes. Remarkably enough, I have never seen the species 

 alive. The specimens iu my herbarium are from Here- 

 ford (Mr. Lees, B.S.L.), York (Mr. James Ward), Diu-ham 

 (Mr. R. B. Bowman), Northumberland (Sii- W. C. Tre- 

 velyan), Dumfries (Mr. Cruickshank), Ross (Rev. George 

 Gordon), Sutherland (Professor Graham).

 Eriophorum supposed to be this species, near Halnaby, in 

 Yorkshii-e, m " a small strip of boggy ground, mostly co- 

 vered with brushwood, on the left hand of the road from 

 Croft, which affords Ranunculus Lingua," &c. (Comp. 

 Bot. Mag. i. p. 290). In the Manual of British Botany, 

 E. gi-acile is said to grow at " Hagnaby, Yorkshii-e;" but
