402 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 



Lansdown, in boggy ground on the slope of a hill, about \ \ miles from 

 Bath. The ground came into the possession of Mr W. Beckford of 

 Fonthill, and was drained and built on. The plant should be specially- 

 searched for in basic bogs or marshes. 



Carex Davalliana. 



Eootstock densely caespitose, with- 

 out elongate stolons. 



Stem usually rough, in upper part 

 more triangular. 



Female spike oblong. 



Fruit, when ripe, narrowly lan- 

 ceolate, reddish brown, \ in., 

 eventually markedly deflexed. 



Other erroneous records are given by Smith in Eng. Fl. iv., 78, 

 namely : — spongy bogs in the County of Down, Sherard ; near Belfast, 

 Templeton ; in a bog near Crossgate toll, and by the Side of Guillon, 

 Edinburgh, Mr Manghan Hooker. Smith, there is no doubt, had 

 Davall's Swiss specimen by him when he described it in Fl. Brit., as 

 no British specimens were known at that time. He mistook Beattie's 

 specimen of C. dioica for this species. 



Carex dioica. 



Eootstock creeping, rarely sub- 

 caespitose with elongate stolons. 



Stem smooth, very faintly trian- 

 gular. 



Female spike ovoid. 



Fruit, when ripe, dark brown, 

 ovate-oval, -J- in., more or less 

 deflexed.
