Abstract

Two non-native vascular plants, Fetid Dogweed (Dyssodia papposa; Asteraceae) and Slender Russian Thistle (Salsola collina; Amaranthaceae), are added to the flora of Alberta, Canada, based on collections and sight records made in 2011. Fetid Dogweed was found along roadsides at eight sites in southern Alberta, and Slender Russian Thistle was found along a hiking trail in Dinosaur Provincial Park near Drumheller. Both species are weedy and are probably expanding their range in North America.
