THE BIOLOGY OF CANADIAN WEEDS.: 32 Chenopodium album L.

Abstract
In Canada, lamb’s-quarters (Chenopodium album L.) occurs in disturbed habitats in every province, the Yukon and the Northwest Territories. A key is provided separating two other closely related weedy species, C. berlandieri Moq. ssp. zschackei (Murr.) Zobel and C. strictum Roth var. glaucophyllum (Aellen) Wahl from C. album. The biology of C. album, the most common weedy species in the genus, is discussed.
