Annual, perennial herb; roots septate; generally monoecious; scape generally straight at inflorescence.Key to Sagittaria
Leaf: petiole cylindric to 3-angled; submersed blades tapered to base; floating or emergent blades generally sagittate ( linear to ovate).
Inflorescence: lowest node generally with 3 pistillate flowers, those above generally staminate.
Flower: sepals 3–10 mm, reflexed to appressed in fruit; petals generally entire.
Staminate flower: stamens 7–30.
Pistillate flower: receptacle convex; pistils many, spiralled on convex receptacle.
Fruit: body generally 2–3.5 mm, strongly compressed, abaxially winged or ridged; beak generally lateral, spreading to erect.
± 30 species: worldwide, especially Am. (Latin: arrow, from leaf shape) Some species weedy; tubers of some eaten by humans, wildlife; Sagittaria brevirostra Mack. & Bush reportedly persisting at Stafford Lake and Chileno Laguna, Marin Co.
