clifcovered it to be different from the Linnjean ^ioica, to which the 

 fynonym of Scheuchzer is referred in the Species Planiarum. Linnxus, 

 however, has erafed this quotation from his own copy of that work. 

 Mr. Davali has affured me this plant is very common in almoft eveiy 

 damp fpot about Orbe ; whereas he had met with the dloica only in 

 one peat bog. I have no doubt of its being what Haller intended 

 under his n. 1350 ; it agrees exaftly with his defcription, though 

 he has confounded under it fynonyms oUioica 2Lnd pullcarls at leafl:, 

 if of no more fpecics. It appears to be the c/ioica defcribed by Pro- 

 feffor Wildenow in his recent treatife on the Carices found about 

 Beriio, printed in the Tranfaftions of the Academy of that place. 

 Scheuchzer erroneoufly applied to it fynonyms of Ray which be- 

 long to C. pulicaris, and has by that means been the caufe of fubfe- 

 quent miftakes. Mr. Davali having firft elucidated the fubjea, I 

 have confecrated the fpecific name to his memory. 



No one had fufpeded this to be a Britifh plant till I received a 

 fpecimen this autumn from Profeflbr Beattie of Aberdeen, under 

 the name of dioica, along with a rich aflemblage of great part of 

 the whole genus. 



C. DavaUiana is readily and effentially diftinguiflied from C. dioica 

 by the fruit being of a triangular-lanceolate, not ovate, form, re- 

 flexed, not erect, and alfo much more ftrongly nerved. No one 

 who has examined both can ever confound them. C. pulicaris h 

 diftinguifhed by being always androgynous, and having fruit altb- 

 gethcr without nerves, lanceolate, and pointed at each end.
