116 85. CYPERACE^. 



Native. Uliginal. To the four counties above men- 

 tioned, those of Aberdeen, Moray, West Inverness, and 

 Dumbarton, with the Isle of Skye, may be added, as 

 known to produce the Carex saxatilis. It has been sug- 

 gested, by Dr. N. J. Andersson, and supported with con- 

 siderable plausibility of argument, or fact, that Carex 

 saxatilis is " the highest alpine form of C. vesicaria." 

 See Bot. Gaz. ii. 253. C. Grahami certainly may be said 

 to make a first step downwards from C. saxatilis towards 

 C. vesicaria, and I suppose its Forfarshire station to be 

 one of the lowest in wliich any form of C. saxatilis is 

 found in Scotland. But the leap fi'om C. Grahami to C. 

 vesicaria is still left wide with us. Grahami is reported 

 from two counties, Forfar and Perth (Br. Flo. edit. 6).

Native. Paludal. In giving the above widely general 

 distribution of this plant, it will be understood that C. 

 flava and C. CEderi are taken together, and that it may 

 possibly not apply to either of them singly. In several 

 instances I am not prepared to say whether both alleged 

 species, or one only, and wliich of them, occm-s in some of
