Almost throughout N. A., except in the extreme North. Native of Eu. 



7. C. hybridum L. Maple-leaved Goosefoot. 



Waste places, mostly in gravelly soils ; frequent. Aug.-Sept. 



Near Coy Glen ; Six Mile Creek ; various places in Ithaca ; and elsewhere. This 

 species occurs occasionally in openings in woods, and on the cliffs at Esty Glen and 

 King Ferry, and in such locations it appears as though indigenous (DA.). 



Que. and Me. to B. C, southw. to Va., Tex., and Calif., including the Atlantic 

 Coastal Plain. Found also in Eu. 



8. C. urbicum L. 



Waste places and shores, in sandy or gravelly soils ; rare. Aug.-Sept. 



Ithaca, Cayuga St., 1880 (£>.), and Aurora St., 1882 (£».); along the lighthouse 

 road, 1921 (S. H. Burnham & C. L. Wilson) ; shore of Cayuga Lake, near Hibiscus 

 Point, 1918; bed of abandoned canal n. of Cayuga, 1919. 



N. S. to Ont, southw. to Md. and Mo. Adventive from Eu. 



9. C. paganum Reich. Pigweed. 



Cultivated fields and waste places, in rich soils, especially about old buildings ; 

 frequent. July-Sept. 



Stratton ; near Coy Glen ; near Buttermilk Creek ; Ithaca flats ; C. U. campus ; 

 near Benson Corners ; Salmon Creek valley ; s. of Union Springs ; and elsewhere. 



Widely distributed in N. A. Naturalized from Eurasia. 



A color form, with the stems brilliantly purple and the leaves and fruit often pur- 

 plish, is frequent on the Ithaca flats. 



10. C. album L. Lamb's Quarters. Pigweed. 



Cultivated fields and waste places, in rich soils ; common. July-Sept. 



Almost throughout N. A., except in the extreme North. Naturalized from Eurasia. 



It has not been possible to separate this species from C. lance olatum Muhl. Numer- 

 ous forms occur which are transitional in all the distinctive characters usually cited. 

 Some of these forms appear to be of undoubted environmental origin. 



2. Atriplex (Tourn.) L. 



0. Leaves lanceolate to narrowly lanceolate, often slightly hastate, usually entire. 



1. A. patula 

 a. Leaves broadly ovate, hastate, more or less irregularly toothed.

 Africa.
