This species has been the occasion of misunderstanding from 

 Schkuhr's time to the present* Neither European nor Ameri- 

 can botanists have taken it up, although credited to both 

 countries. It has been, perhaps, the most puzzHng feature 

 in our Carex synonymy. The best specimens are in Willdenow's 

 herbarium. Professor Ascherson suggested to me the identifica- 

 tion of the plant with Reuter's C teiiax of the ItaUan Alps. 



The three following of Schkuhr's species are not in his herb- 

 arium, nor in Willdenow's : C. btillata, tctanica, Miililcnhergii, 



C, bromoides and C. Willdcnovii are in Hb. Willd.

 Wahl. Altliough Allioni places this species in the section 

 characterized by *'Spicis pluribus sexu distinctis: mare 

 unica," it has an androgynous terminal spike. It is rep- 

 resented by a good specimen.

C. bipartita: Kobresia caricina,V\^\\\d. Allioni's figure of this 

 plant is not characteristic, yet the specimens are unmis- 

 takable and their history is clear. In Balbis' herbarium, 

 at Turin, the same plant is labeled C. bipartita. 

 Some of Allioni's species are not known to be in existence, 

 and his figures are poor. His figure of C, irigona, however, ap- 

 pears to leave no doubt that he meant the plant named by Lin- 

 naeus C. distans.
