CHENOPODIUM ALBUM L. 



Rather common ; found in flower along the railroad by the ice- 

 houses June 21, 1901. Very abundant in a field north of the lake, 

 excluding nearly everything else. Frequently used as a pot-herb. 

 The form collected at the lake was the subspecies viride (L.) Moq. 



308, MAPLE-LEAVED GOOSEFOOT 



CHENOPODIUM HYBRIDUM L. 



Not especially abundant ; found growing in waste places. Leaf 

 unusually thin for the genus. 



309. FEATHER GERANIUM; JERUSALEM OAK 



CHENOPODIUM BOTRYS L. 



During 1900 and 1901 only a few scattered plants were seen 

 along the railroad in front of the Assembly grounds and by Win- 

 field's. In 1906 and succeeding years it was found quite abundant, 

 forming considerable patches in a sandy field north of Lost Lake. 

 An interesting and pretty plant of low growth, compact and slender 

 but bushy habit, with thick whitish narrow leaves which fall off 

 early in autumn, leaving a wandlike skeleton, ghostly in effect. The 

 whole plant has a pleasing fragrance. 



310. WINGED PIGWEED 



CYCLOLOMA ATRIPLICIFOLIUM (Spreng.) Coult. 



A new arrival at the lake, having been first seen in the im- 

 mediate vicinity in 1909, though in 1906 it was found along a road 

 several miles west of the lake. It is common on the sand dunes 

 about Knox, Indiana. The plants at Culver were growing in a row 

 along the edge of a vacant lot at Culver, where the sod was broken, 

 leaving naked sand. The plants both here and at Knox formed 

 almost perfect balls of light green, which, among the barren sand 

 at the latter place, showed up conspicuously. They are almost as 

 handsome as the closely related and well known Kochia scoparia 

 which is coming into general use in flower gardens, but they 

 do not have the splendid autumn foliage of the latter. Some of 

 the inhabitants of Culver called them "Kansas tumbleweed." The 

 form is admirably adapted to rolling over ground and it was prob- 

 ably by this means that they reached the lake.
