III. Eleocharis R. Br. " Spike Rush " 



1. E. obtusa (Willd.) Schultes. Annual. In mud holes. 



Rare. Nemaha, Nemaha Co. (Bates) ; Minden (Dr. Hape- 

 man) ; Lincoln; Nebraska City (Uni.). 



2. E. engelmanni Steud. Annual, In mud holes. Rare. 



Minden (Dr. Hapeman). 



a. var. detonsa Gray. Springview, Boyd Co. (Bates) ; 

 Saunders Co. (Uni.). 



3. E. palustris (L.) R. Br. Perennial. In saturated soil. 



Very variable. Chadron, Dawes Co. ; Arabia, Cherry Co. ; 



Springview; St. Paul; Red Cloud (Bates); Thedford; 



Cody's Lakes, Grant Co.; Lincoln (Uni.). 



My collections from Chadron, St. Paul and Red Cloud 



are absolutely flat stemmed and make as good a var. as 



many that are published. I shall call them here simply 



forma compressa. 



At Chadron this form occupies a basin of several acres, 



and is cut for hay whenever the season leaves the mud dry 



enough for teams. It produces a heavy crop and is highly 



esteemed. 



a. var. glaucescens (Willd.) A. Gray. Pauline (Dr. Hape- 

 man) ; Anselmo, Custer Co. ; Natick and Thedford, 

 Thomas Co.; Sheridan Co. ; Lincoln; Minden; Deuel Co. 

 (Uni.); Glenn, Sioux Co.; Crawford and Bordeaux, 

 Dawes Co. ; Valentine ; Kennedy ; Long Pine ; Arabia ; 

 Ewing (Bates). Our common form. 



forma calva, without bristles, in black alkali, Bassett, Rock 

 Co.; Eli, Cherry Co. (Bates). 

 The var. glaucescens is much more common than the 



species. 



For several years past, I have considered glaucescens a 



good species. But, upon getting all our material together, 



I find there is no absolute dividing line. It is an excellent 



var. 



4. E. acicularis (L.) R. and S. Perennial. In saturated soil, 



mosslike, growing well but not fruiting under water. Min- 

 den (Dr. Hapeman); Valentine; Wood Lake; Atkinson;
