Plants dioecious (rarely polygamomonoecious). Leaf blades hastate with spreading basal lobes, or sometimes narrowly linear, unlobed, and narrowly cuneate at base. Pedicels filiform, articulation distinct near base of tepals, slightly swollen. Flowers unisexual, staminate and pistillate on different plants; outer tepals angled towards inner tepals; inner tepals not enlarged or slightly to distinctly enlarged, 1.2–2.5(–3) mm, equaling or slightly wider than achenes, margins entire; tubercles absent.
Distribution
Mostly in temperate regions of both hemispheres, as naturalized almost worldwide.
Discussion
Species 7–8 (4 in the flora).
