CHENOPODIXJM, Tourn. Goose-foot. Pig-weed. 
888. C. album, L. Lamb’s-Quarters. 
Cultivated grounds, roadsides, old fields, etc. ; common or abundant. 
July — September. 
This is a very variable species, but is rather polymorphous, than in- 
cluding distinct varieties. 
839. C. urbicum, L. 
In waste places; infrequent. 
840. C. hybridum, L. Maple-leaved Goose-foot. 
Waste grounds everywhere; common. July — August, occasionally 
as early as June. 
Quite variable as to size and shape of the leaves, and height of 
plants — 2 to 5 feet high. 
841. C. glaucum, L. Oak-leaved Goose-foot. 
In streets and waste places; frequent. 
Brackish borders of Lake Calumet, 1886-’87. 
842. C. botrys, L. Jerusalem Oak. Feather Geranium. 
Occasionally found along the lake shore from South Chicago, south- 
ward. June 25th — September. 
843. C. ambrosioides, L. Mexican Tea.

ATRIPLEX, Tourn. 
844. A. patulurn, L. Orache. 
Summerdale, Johnson. Chicago, Babcock. 
845. A. patulurn, L., var. hastatum, Gray. 
Along Archer Ave. ; local, Babcock. 
In this locality it seems to have been exterminated. The banks of 
the Chicago river in the Bridgeport and Brighton districts, where 
there is no dockage, furnishes the proper soil. Near Brighton, 
1880, S. B. Copeland. Stock-yards, University of Chicago Herb., 
credited to Babcock. Englewood, Hill. Along the canal, a short 
distance east of Summit, 1883, C. P. Murray. 
These reports would indicate that this species is indigenous to the 
district, from Bridgeport, southwest; a territory subject to constant 
changes. This may account for its rarity and apparent extermin- 
ation. 
CORISPERMUM, Ant. Juss. 
846. C. hyssopifolium, L. Bug-seed. 
Along the lake shore; frequent. Lake Calumet, east shore; rare. 
Sand of the lake shore; abundant, 1870, Babcock. September.
