Fresh-Water Algae. VIII. 
By Francis Wolle. 
(riate xLiv.) 
In tlie summer of 1883 I made my tenth annual visit to the 
haunts of fresh-water Algce, choosing those in our neighboring State 
of New Jersey where the ponds are more numerous as well as more 
accessible than in Pennsylvania.. In the vicinity of Ocean Beach, 
Monmouth Co., there is a number of what may be termed small lakes, 
the waters of which, though separated from the ocean by only a nar- 
row strip of land, are very clear and fresh. Therein are to be found 
many Interesting plants; among others I saw, for the first tune, Utric- 
ularia inflata, a very distinct and beautiful species of bladderwor , 
swimming free by means of the inflated petioles, arranged in a wliorl, 
bearing in the centre a perpendicular scape with large yellow flowers. 
From among the aquatic plants I gathered many algffi, and, among 
these, the following desmids new to our flora: ^ . , o. / 
Cosmarium debressum, Nsg,, and C. ohsoletum, Renisch ; Staunist- 
rum pachyrynchiiim, Nord. (Plate xLiv., Figs. 32-36); ^- monticolum, 
Lund. (Figs. 24-26: and ' . . „ , 
S. iotSmum, «.^A (Figs. 5-7)-^'ery minute; semicells quad- 
rangular, angles drawn out into thin, divergmg, granular rays eacn 
about as long as the diameter of the body, apices obtuse; end view 
triradiate. Diameter, including the rays, i5-2o/<. 
A small species, quite plentiful at Ocean Beach and at Malaga,

Two other desmids, not new, but rare, were also found here, viz: 
Cosmarium sportella and Euastrum attenuatum. 
From the ponds in the vicinity of Malaga, Gloucester County, 1 
was fortunate enough to secure five new desmids, viz.: 
Staurastriim leptacaiithum, var. tetroctocerum, n. var K^^'i^- 
29-30)— Semicells suborbicular furnished with eight, long, thin ray.s, 
deeply forked, or clawed at the ends; this whorl rather below the 
middle, and another above it with four similar rays; end vicsv 
octangular, each angle produced into a long thin ray; between the 
margin and the centre are four more rays. Membrane smooth.

The only esse^.tiil distinction between this form f"d Uk. WC'^^ 
Brazilian plant is that ours has ei^hi and four rays in the two whorl., 
and the Brazilian plant has six and four rays.
