Nine years after Wahlenberg had published his Carex lurida, 

 he stated (Fl. Lapp. 250) that it is the same as Schkuhr's figure of 

 C, hipulina^ Muhl. I therefore used his name for C. lupulina 

 in my Synopsis (Proc, Amer. Acad. Arts and Sci. xxii. 63, 

 1886). In the Riksmuseum there are two sheets labelled C. 

 lurida by Wahlenberg. One is from Hultgren, the original 

 collector, and from this the description is made. This plant 

 is the C, tentaculata of Muhl. ! The other sheet, evidently 

 a later acquisition, is from lyiuhlenberg, and is C. hipiilinay 

 Muhl, Yzx. pedimcidata, Dewey. It is evident that Wahlenberg 

 confounded the two species. C. lurida is a variable species, par- 

 ticularly in the size and shape of the spikes, but I am able to 

 separate only one form as worthy v^arietal recognition : 



y Var. GRACILIS. 



C. tentaculata, Muhl., var. gracilis, Boott, III 94 (i860). 



Small and slender, bearing about two small erect pistillate 

 spikes'which are densely cylindrical and very narrow. Moun- 

 tains of Vermont and New^ Hampshire, and in Pennsylvania and 

 Tennessee.

Carex lupulina is a variable and perplexing species. The 



type is characterized by its very thick and short spikes (i^ to 2 



inches long and an inch or more wide), which are strictly sessile, 



or the lower one short-peduncled, and contiguous into a great 



",
