Lake Maxinkuckee, Physical and Biological Survey 397 

 622. HEDGE BINDWEED 



CONVOLVULUS SEPIUM L. 



The most common of the wild morning-glories about the lake. 

 It is not a nuisance in this region, as it is confined mainly to the 

 railroad embankment, where it grows in the ballast, trailing over 

 the bank or twining about other herbs. It begins flowering in early 

 June and continues throughout the summer. 



623. UPRIGHT BINDWEED . 



CONVOLVULUS SPITHAMAEUS L. 



A rather small dwarfed bindweed, found somewhat frequently 

 along the railroad track, especially in the neighborhood of the 

 Outlet bridge where it grows in the ballast on each side of the 

 track. Though fairly common in parts of the state, it is neither 

 so abundant nor of such rank growth as to become as great a 

 nuisance as several of the other species occasionally do. 



FAMILY 122. CUSCUTACE^E. DODDER FAMILY 

 624. FIELD DODDER 



CUSCUTA ARVENSIS Beyrich 



During the early years of the survey this was not an especially 

 common plant; occasional plants were found on clover in Green's 

 meadow. Of late years it has increased considerably, and in 1909 

 clover fields near Culver were badly infested, the masses of dodder 

 showing in the distance as great yellow patches. Where it has 

 gained a foothold it threatens to become a bad weed and difficult 

 to control or eradicate. 



625. COMMON DODDER; LOVE VINE 



CUSCUTA GRONOVII Willd. 



Rather common on herbs and low shrubs such as golden-rod 

 and willow along the shore of the lake. Found along the south 

 shore of Outlet Bay and in the strip of marsh by the lake below 

 Farrar's. Not an especially conspicuous plant. Young willows 

 are occasionally killed by it. As it confines its attention to unculti- 

 vated plants, it does not assume the economic importance that the 

 field dodder does. 



626. GLOMERATE DODDER 



CUSCUTA PARADOXA Raf. 



Not noted about the lake until 1909, when a large patch was 

 found some distance down the outlet. The plant had here obtained
