A PRELIMINARY REPORT ON THE DESMIDS OF 
CONNECTICUT.! 
C. J. HYLANDER. 
I. INTRODUCTION. 
Or 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 ənd 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. i 
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 
! Contribution from the Osborn Botanical Laboratory.
