A PRELIMINARY REPORT ON THE DESMIDS OF 

 CONNECTICUT. 1 



C. J. Hyiander. 



I. Introduction. 



Of the New England States, New Hampshire, Massachusetts, 

 Rhode Island and Maine have had their desmid flora investigated by 

 Bennett, Cushman, Johnson and Harvey. The only published list 

 of Connecticut desmids, however, is the one found in H. W. Conn 

 and L. W. Webster's " Preliminary Report on the Algae of the Fresh 

 Waters of Connecticut (2)." Conn and Webster enumerate 109 

 species and varieties of desmids in their report, but their list is un- 

 satisfactory in that it contains no accurate data and that no localities 

 are given. Since they state in their introduction that the majority 

 of their collections were made from the vicinity of Middletown, I have 

 taken the liberty to list any species found by them, as coming from 

 Middletown. 



Except for the above-mentioned report, the only references to 

 Connecticut stations are found in general reports on North American 

 species. In 1894, L. N. Johnson, in his articles on "Some new and 

 rare desmids of the United States" (5,6), includes several Connecticut 

 localities, most of which are from the vicinity of Bridgeport. Four 

 years later, after Johnson's death, W. & G. S. West worked over 

 some of his material and published their results in a report on " Some 

 desmids of the United States (7)"; this includes also some Con- 

 necticut localities, all from the vicinity of Bridgeport. 



The only other references to Connecticut records are the following: 

 one species of Penium, reported for Connecticut by Wolle in his
