Lake Maxinkuckee, Physical and Biological Survey 157 



tively inconspicuous. It grew very abundantly at Long Point, both 

 on stones and weeds, and was found attached more sparsely to 

 weeds in other places, as at Kruetzberger's pier. 



At Long Point, after the water had retreated from the rocks 

 where this alga had been growing, it died and bleached out, leav- 

 ing a firm, linty covering on the rocks. 



The specimens agree very closely with Wolle's figures of lands- 

 boroughii, but are considerably more slender than given in his de- 

 scription, the following being the measurements : 



Length of cells 62 mic., diameter 22 mic., the younger being 

 55 mic. long and 20 mic. in diameter. Oogonium, diameter 45 mic., 

 length 65 mic. Egg cell, diameter 30 mic., length 50 mic. Male 

 filaments somewhat more slender. Spermogonia usually 7 or 8. 

 The plants fruited abundantly during the summer, the oogonia 

 being frequently two or three in succession, green when young, rich 

 brown when ripe. Terminal cell blunt, opening of oogonium above 

 the middle. 



75. CEDOGONIUM LONGATUM Kuetzing 



A dwarf species, common at Long Point, attached to other algae. 



76. CEDOGONIUM LANDSBOROUGHII (Hass.) 



Common in filamentous material gathered for diatoms near 

 Kreutzberger's pier, July 24, 1906. Male plants uusually called 

 spermogonia common. 



THE CHARACE^E 



One of the first things to attract the attention of the visitor to 

 the lake who is interested in the aquatic flora is the abundance and 

 variety of the peculiar and attractive group constituting the 

 Characese. The greater part of the shallow bottom of Lake Max- 

 inkuckee from a foot or 18 inches to 8 or 10 feet, is covered with a 

 stout Chara 8 or 10 inches high, yellowed or browned with an in- 

 crustation of lime and forming a dense mat over most of the bottom 

 like a brown, subaqueous meadow. 



A visit to Lost Lake but intensified the impression produced by 

 Lake Maxinkuckee. The subaqueous meadow was lacking, in- 

 deed, but the shore was lined with various strange forms, some of 

 them with a silky softness as compared with the harshness of most 

 common forms, the plants bushy with an abundance of slender, 

 delicate leaves and glowing with an abundance of red fruit, while 

 in the depths of the lake, arising from the black mud, were long, 

 slender, semitransparent forms, and others strong, robust and
