I am informed by Dr, Graham that this plant was found by Dr, Wight, 

 July 30, 1832, " in a wet spot about half-way up the clifF, on the south side of 

 Glen Phee, Clova ; the station very circumscribed, being a circle of from twelve 

 to twenty feet ;" and that neither this nor any form of C, saxatilis has been met 

 with elsewhere in Clova; the station Glen Dole, affixed to some specimens, 

 being incorrect, 



I subjoin a detailed description of C. saxatilis, Linn, {C.pulla, Good,), that 

 the two plants may be more distinctly contrasted.
