Lake Maxinkuckee, Physical and Biological Survey 339 



Green's woods June 19, 1901. The plant turns black after frost 

 and the foliage falls, leaving the naked branch surmounted by the 

 raceme of large conspicuous pods. 



434. WILD LUPINE 



LUPINUS PERENNlS L. 



Common in the Culver cemetery where it was noted in blossom 

 May 18, 1901 ; also scattered in woods near a tamarack marsh near 

 the dune region. In many parts of the state it is found principally 

 along railroads. 



435. BLACK OR HOP MEDIC 



MEDICAGO LUPULINA L. 



Rather rare, and apparently of recent introduction ; a few scat- 

 tered plants found along the north shore of the lake and in grass on 

 the depot grounds. Frequent in the state along roadsides. 



436. WHITE SWEET-CLOVER 



MELILOTUS ALBA Desv. 



Not so abundantly introduced as in many parts of the state; 

 at present found in rather small patches along the railroad on a 

 hill near the depot, on Long Point, and on a roadside east of 

 the lake. It is one of the earliest plants to put forth green leaves 

 in spring. In blossom by June 26, 1901. It frequently continues 

 to blossom after pretty severe frosts, and was still in blossom Oc- 

 tober 25, 1904. 



In most parts of the state this plant is found only in waste 

 places and along roadsides. It first appears in or about cities, 

 from which it travels outward along highways and as one goes 

 out farther and farther into the country the roadside patches 

 break up and disappear. Although it gives the places where it 

 grows an unkempt appearance, it does not appear to invade culti- 

 vated fields and gives no indication that it will ever become a bad 

 weed. It grows with surprising luxuriance on dry sandy or grav- 

 elly soils where few other plants will grow at all. Stock of any 

 kind will not touch it except in exceptional instances, although it 

 is said they will eat the hay. It makes good bee pasture, and it is 

 said to inoculate the ground so that alfalfa will thrive where it 

 has grown. Seed is sold by some seedsmen under the name of 

 Bokhara or bee clover. It is of considerable value in adding humus 

 to poor soils and it appears to be one of the few European weeds 

 whose introduction is not to be regretted.
