fined to the localities just mentioned. It seems to be increasing 

 somewhat along the railroad, and in 1904 was found on the bank 

 of the lake near the depot grounds. Occasional along the railroad 

 northward. 



817. LARGER OR SMOOTH BUR-MARIGOLD 



BIDENS LAEVIS (L.) B. S. P. 



Occasional on the west shore of the lake. In general it is 

 usually found in wet places, as on edges of the lakes and 

 streams. Abundant by Winfi eld's, and by the low woods near 

 Overmyer's. Found by McSheehy's pier, by Darnell's, north end 

 of Long Point, by the Assembly grounds, and by Norris Inlet. It 

 does not appear to be so much of a nuisance as some other mem- 

 bers of the genus. 



818. SMALLER OR NODDING BUR-MARIGOLD 



BIDENS CERNUA L. 



One of the most abundant of the bur-marigolds ; found scattered 

 along the west shore of the lake; most abundant about the edges 

 of the flat marshes, a belt surrounded Green's marsh and the marsh 

 about Lost Lake, and the borders of the marshy region along Lost 

 Lake outlet ; also, along the edges of Inlet marsh. In these places, 

 after the plants had ripened and turned brown, it formed a very 

 conspicuous marginal belt. It was still in blossom October 24, al- 

 though the older heads had begun nodding by September 26. In 

 addition to the large, more conspicuous blossoms, the plant has very 

 minute flower-heads in the axils of the leaves, consisting of only a 

 few florets apiece. The nodding habit of the fruiting head is rather 

 peculiar; it may be an adaptation to enable the seeds to attach 

 themselves to the backs of small mammals running through the 

 grass. 



819. PURPLE-STEMMED SWAMP BEGGAR-TICKS 



BIDENS CONNATA Muhl. 



Quite common in marshy places and along the west shore of the 

 lake. Also on shore at the Academy grounds and behind the ice- 

 beach east of the Inlet. Common at Long Point, behind the ice- 

 beach beyond Norris Inlet, and south of the Scovell cottage. Al- 

 though not so great a nuisance as some of the forms which grow 

 in cultivated grounds, this species with its numerous bristling seeds 

 is very undesirable.
