Stem: caudex short. Leaf: basal, simple, palmately veined, floating or not; submersed generally linear to ovate; emergent linear to sagittate. Inflorescence: generally scapose, umbel-, raceme-, or panicle-like; flowers, branches whorled. Flower: radial; sepals 3, generally green, generally persistent; petals 3, generally > sepals, white or pink; stamens 6–many; pistils 6–many, free or ± fused at base. Fruit: achene, generally compressed, beaked.

Key to Alismataceae
Annual, perennial herb; roots septate; generally monoecious; scape generally straight at inflorescence. 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.Key to Sagittaria
± 30 species: worldwide, especially America. (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.
