ALG^. 



The Algse have received no attention so far as specific determin- 

 ation is concerned. In the collection of material for class use in 

 the laboratory it has been found that cjuite a large number of genera 

 are represented, some of them by a number of species. Among 

 these Spirogyra, Zygnema and VaiicJieria may be named. Diatom- 

 acece are everywhere but the Desmidiacece are not so well represented. 



Among the larger forms the two following are conspicuous in the 

 ponds at the city springs : 



Chara fcetida, A. Br. 



It forms a dense growth over the bottom of the ponds, in places 

 reaching a foot or more in height. 

 Batrachospermum gelatinosum, (L.) A. F. Woods, Rep. Bot. Surv. 

 Neb. iii, 6 (1S94). 



Adherent to stones in running water. 



Chara sp. 



A rather unusual Chara was collected in a pool in the mouth of 

 an extinct geyser pan on Warm Spring Creek. It is in the hands 

 of Mr. J. W. Blankinship for determination; August 9, 1894 (No. 

 796).
