Native. Uliginal. Chiefly found along the table-land 

 of the mountain range which forms the boundary line of 

 Forfar and Aberdeen shires, and on both sides of the wa- 

 ter-shed. It is said to occur also on Loch-na-gar (Mr. H. 

 M. Balfour), and Cairngorum (Rev. Mr. Eraser). Much 

 doubt attaches to the more northerly habitat of Suther- 

 land. Professor Graham, along with Mr. W. A. Stables 

 and Mr. W. H. Campbell, pronoimced the i^lant of Su- 

 therland to be C. rariflora; but my specimens from that 

 county, gathered hj Dr. G. Macnab and the three other 

 botanists mentioned, appear to be nearer C. limosa. Dr. 

 Graham wrote thus in 1833 ; " Carex rariflora. — Ob- 

 served near Oikel, by Mr. McNab. I afterwards found it 

 by the road opposite the west side of Ben Hope; and Mr. 

 Tyacke found it at the base of Ben Loyal. In 1825, Mr. 

 Holme and I found it in Batcall Moss, between Riconick 

 and Oldshore. I then considered it C. limosa, and I am 

 still inclined to agree with those botanists who can see no 

 good specific distinctions between C. rariflora, C. limosa, 

 and C. irrigua."
