160 Lake Maxinkuckee, Physical and Biological Survey 



5. CHARA GYMNOPITYS A. Braun 



Common on the large quaking bog surrounding the north end of 

 Lost Lake, growing almost out of the water. Rare in Lake Max- 

 inkuckee, two examples being found near shore in the region of 

 the green boathouse by Norris Inlet in the autumn of 1900. 



This species is heavily branched, and is exceedingly soft and 

 fine, of a delicate, bright green color. It fruits heavily, and is an 

 annual, generally disappearing before frost. 



6. CHARA SUBVERRUCOSA A. Braun 



Occasional in the lake, represented in the collection by several 

 specimens. Dr. Robinson says of these : "A majority of the plants 

 appear direcious, antheridia being very rarely found, but they are 

 present in a number of cases." 



7. NITELLA TENUISSIMA (Desv.) 



An exceedingly dainty little Nitella growing in shallow water 

 (1-3 feet) along shore in the neighborhood of Farrar's. The whole 

 plant grows in rather dense tufts about 25 mm. in diameter. Color 

 dark green; rhizoids not conspicuous, main stems many, exceed- 

 ingly slender, internodes hardly more than 2 mm. long. Leaves in 

 whorls making a dense, globular mass at each node, so that the 

 plant looks a good deal like large Rivularia spheres attached to a 

 slender stalk. These spheroids of leaves, or whorls, are larger and 

 closer together toward the apex of the plants. 



8. NITELLA BATRACHOSPERMA (Reichenbach) 



One specimen from Lost Lake. Dr. Robinson says of it: "No. 

 1576 (578) agrees well both with the description and with named 

 material in the Allen collection of Nitella batrachosperma (Reichb.) 

 except that no trace can be seen of mucus in which the fertile 

 verticils in that species are usually contained. Possibly therefore 

 it may be N. tenuissima Kuetzing which is very similar, but the 

 former alternative is greatly preferable." 



9. NITELLA MUCRONATA A. Braun 



A delicate species growing in the muddy bottom of Lost Lake. 

 One of the most attractive species of the region. Abundant at 

 Bass Lake. 



10. NITELLA MONODACTYLA A. Braun 



Reported from two specimens. We have no record of its dis- 

 tribution.
