Incognit. " Glen Cally, Mr. Q. Don. No other bo- 

 tanist, i^erhaps, has found this gi-ass in the locality named, 

 which is a long narrow valley descending from the high 

 mountains near the head of Caness into Glen Isla. It 

 does not gi-ow about the head of the glen, which was care- 

 fully examined in July, 1848." (Gardiner's Flora of For- 

 farshire).

Native. Paludal, &c. A local plant in Britain, as yet 

 known only in the four counties above mentioned. The 

 lowest altitude seems almost to bring it within the infer- 

 arctic zone ; but it is seldom seen so low as 700 yards, 

 and perhaps only in unfavourable aspects. Though 

 usually in wet or even watery jjlaces, occasionally it may 

 be seen in those which would be rather designated " pra- 

 tal," than " paludal," if they were situate in the agrarian 

 region ; but " meadows " can hardly be said to exist in
