Description: Lesser Burdock or Common Burdock (Arctium minus). At entrance to Marine Park Saltmarsh trail at Burnett Street, Brooklyn, NY. Two groups of plants: first group photos 1-7; second group photos 8-12. Although the leaf petioles are grooved along their upper surface the petioles are hollow, as seen clearly in the photographs. Considering only Arctium minus and Arctium lappa, the hollow leaf petiole is diagnostic for Arctium minus, according to all the standard floras for this region as well as Europe (region of origin of these species).
