The plant which we collected upon Mt. Elbert shows a pecu- 

 liar deviation from the type by being tristigmatic, besides that 

 the utricle is very prominently slit on the outer or convex 

 face. We liave not, however, felt justified in regarding this 

 as a distinct species, inasmuch as the number of stigmas is not 

 a constant character within the genus Carex^ even if the species 

 in question be one of the Vignece. It is, also, to be pointed 

 out that we were unable to detect any divergence w^hatsoever 

 in the anatomical structure of the vegetative organs which we. 

 compared with those of typical individuals from Greenland, 

 ISTorway, Alaska and British Columbia. Similar specimens 

 with three stigmata were also observed in the copious material
