Lake Maxinkuckee, Physical and Biological Survey 447 



perched on old heads of this plant, sending silken parachutes a-fly- 

 ing, is in many parts of the state a characteristic bit of autumn 

 scenery. 



836. TALL OR ROADSIDE THISTLE 



CIRSIUM ALTISSIMUM (L.) Sprcng. 



A few plants found on the east side of the lake, along the road 

 in moist places north of Aubeenaubee Creek and at the springy flat 

 near Overmyer's field. Noted in blossom as late as October 25, 

 by Aubeenaubee Creek. A rather handsome plant, and never com- 

 mon enough to become a nuisance. The tall stem is hollow, form- 

 ing a large tube, but it splits rather easily. 



837. SWAMP THISTLE 



CIRSIUM MUTICUM Michx. 



Found by the Lakeview Hotel and in the springy flat near Over- 

 myer's field. Scattered generally in swamps. A harmless plant, 

 not very persistent and only weakly prickly, with handsome flowers. 



838. CANADA THISTLE 



CIRSIUM ARVENSE (L.) Scop. 



Growing along the shore by Long Point, only a few plants; 

 quite abundant in an old field northeast of the lake along the wagon 

 road, and along a ditch on the way to the drained lake. The most 

 pernicious weed in our area, rapidly spreading and very difficult 

 to eradicate.
