Mackenzie : Notes on Carex 263 



lected by Nuttall, is a later addition. But finally, and most impor- 

 tant of all, Dewey's description is accompanied by a plate {W.f. 72). 

 This plate clearly shows that it was the third plant on the sheet in 

 the Torrey herbarium which Dewey had in mind. This plant, 

 which I have examined, is Carex Liddoni Boott, as stated by Pro- 

 fessor Bailey. As this last-named species was not published until 

 1840 (Hook. Fl. Bor.-Am. 2: 214) it should be superseded by 



Carex petasata 

 pliacocepJiala r 



ion of C petasata with C. 

 our western Cariccs were 



but little known, and is entirely baseless, so far as I know. 



Of Carex phaeocephala I have seen the following specimens :
