XXII. On a -Species of Carex allied to C. saxatilis, Linn. 

 By Francis Boott, M.D., F.L.S. <§-c. <§-c. 



Read December 19th. 1843. 



In 1832 a Carex was found in Glen Phee, Clova, by the party accompanying 

 Dr. Graham of Edinburgh upon his annual botanical excursion to the High- 

 lands of Scotland, which has been considered as a form of C. saxatilis, Linn. 

 {C. pulla, Good.), and to which my attention was lately called by Mr. 

 W. Wilson of Warrington, who in a letter of December 4th says : — " It dif- 

 fers from C. saxatilis in having distinctly ribbed fruit, in being much taller, 

 and of a different colour." 



I was led by this particular allusion to the plant to examine it minutely, 

 and believing it to be a species, have named it after my excellent friend 

 Dr. Graham ; and I offer the following description of it, and the observa- 

 tions on C. saxatilis, Linn., which naturally arise out of the consideration of 

 a plant hitherto associated with it. 



Carex Grahami. 



Spicis 4-5 cylindricis ferrugineis ; masculis 2 (rariiis 1) gracilibus acutis : 

 foemineis 2-3 subremotis crassis obtusis inferioribus pedunculatis evagi- 

 natis subnutantibus, stigmatibus 2, perigyniis oblongo-ovatis rostratis 

 bifurcatis inflatis nervosis suberectis ferrugineis (rariils stramineis) basi 

 pallidis squama ovata acuta fusca apice albida nervo pallido duplo lon- 

 gioribus. 

 Hab. Glen Phee, Clova, in Scotia.
