Discussion
Conringia orientalis was collected on ballast in New York as early as 1879. It is most abundant in the plains and prairies of both the United States and Canada (I. A. Al-Shehbaz 1985; R. C. Rollins and Al-Shehbaz 1986). In disturbed places, it has penetrated into the native vegetation over a wide area.
