The accompanying drawings (figs. 1-20) illustrate perigy- 

 nia and scales of Carex Barbarce Dewey, and of some other 

 species which by subsequent authors have been referred to this 

 species. It is readily to be seen that the figures of Dewey's 

 own but immature specimen (figs. 1-3) agree very well with 

 those collected by Mr. Parish (figs. 4-5) ; furthermore, that 

 Dr. Hayden's specimens from Lake Fork (figs. 6-8) are 

 undoubtedly C. Nebraskensis Dew. Then there is the plant 

 which Dewey himself identified as C. Sitchensis Presc. (figs.
