Lake Maxinkuckee, Physical and Biological Survey 175 



near the green boat-house, by Norris Inlet, etc. A fine patch grew 

 at the head of the thoroughfare between the lakes, above the wagon 

 bridge. The plants frequently grew out in long straight rows from 

 shore, the different stems coming up in line from a white strong 

 underground rootstock. 



20. WHORLED WATER-MILFOIL 



MYRIOPHYLLUM VERTICILLATUM Linn<eus 



Found growing in both lakes, not deeper than 14 feet. Abund- 

 ant and widely distributed, growing in rather compact patches 

 with other plants where there is rich bottom and rather shallow 

 water (6 to 10 feet), as about the west edge of Outlet Bay, in the 

 neighborhood of the Ice-houses, about Norris Inlet and most of 

 Lost Lake. It grows far out in the water at a point in line with 

 Norris pier and opposite Overmyer's field. It also grows near 

 Norris Inlet. 



The plants retain their form during the winter, but become 

 very brown and homely, the tips forming rather compact buds 

 not nearly so neat and well differentiated from the rest of the 

 plant as those of M. spicatum. Found in flower September 1, 

 1900. Flowers and fruit, as in others of the genus, inconspicuous. 

 During April (5th, 6th, 7th, 12th and 13th) a large number of 

 buds were washed ashore in the neighborhood of Long Point and 

 Outlet Bay, and became greener and brighter as the days passed. 



On April 14 the plants looked much as they had in winter, 

 only a trifle greener. On April 19 the buds were quite green, 

 and by April 23 the buds had begun to elongate and were con- 

 siderably looser than had been noted before. 



21. CLASPING-LEAVED PONDWEED 



POTAJWOGETON PERFOLIATUS Linnaeus 



Not common in general, but fairly abundant in a few localities 

 in the south part of the lake. More common in water from 8 to 

 12 feet deep. It does not form patches but is dredged up inter- 

 mixed with other weeds. Some plants were found growing in 

 sandy bottom in water about 8 feet deep in the neighborhood of 

 the Merchants' pier. A good patch was also found, in 1904, near 

 the Ice-houses. 



In form this is one of the most regular and attractive of the 

 pondweeds ; the broad wavy close-set dark-green leaves in 2 ranks 

 giving it the appearance of a full plume quite different from the 

 broad open plume of P. robbinsii. It is not so showy in the water
