The Sedges of Nebraska 2i 



collection of Sept. i6, 1893, Neligh, Antelope Co., on the 

 banks of the Elkhorn River, is magnificent in size, color and 

 squarrose perigynia. March 26, 1910, I collected the sterile, 

 leafy culms of 1909 at St. Paul, Neb., grozving at top and 

 side shoots, and have them mounted. They had shot out 

 1-2 inches of green growth. 



46. C. mirabilis Dewey. One over-ripe sheet from Nemaha must 



go here (Bates). 



C. mirabilis Dewey var. perlonga Fernald. Dry woods. 

 Nebraska City (Uni.) ; J. J. Thornber, only i sheet. I 

 have a sheet from Central Michigan that agrees well with 

 this. 



47. C. straminea Willd. 



var. echinodes Fernald. " Kearney, Islands of Platte River, 

 July 20, 1901 " (Uni.), J. J. Thornber. A fine sheet. 

 It is a pity we have not more of it. 



48. C. festucacea Willd. In dry soil, extending to the margin of 



swales, Minden (Dr. Hapeman) ; Franklin; Hitchcock Co.; 

 Halsey (Uni.); Nemaha; Valentine; Beatrice (Bates). 

 My Beatrice collection and one sheet from Nemaha might 

 pass for suberecta (Olney) Britton, on account of width of 

 perig}mia, but the description of scales does not call for any 

 change. I doubt the necessity of the new species. C. fes- 

 tucacea is an extremely variable species, but the variations 

 can be found on the same plant, as in species of Crataegus. 

 a. var. brevior (Dewey) Fernald. Nebraska City; Lin- 

 coln; Ponca; Anselmo; Kearney Co. (Uni.); Arabia; 

 O'Neill; Long Pine; Ewing (Bates). A variety of no 

 importance, as it is quite uncertain under which head to 

 put some of our forms. Perhaps the most universal 

 species in the State. 



49. C. bicknellii Britton. In low meadows. O'Neill and Ewing, 



Holt Co.; Weeping Water, Cass Co. (Bates),
