Stems rhizomatous , creeping , with abbreviated erect axis at nodes, or erect, leafy, elongate . Leaves basal, alternate, opposite, or whorled , sessile or petiolate ; stipules sometimes present, forming tubular sheath around stem; blade margins entire or serrate; veins 1--many. Inflorescences axillary , terminal , or scapose , 1-flowered or cymose , subtended by spathe ; spathe a 2-fid bract or pair of opposite bracts. Flowers unisexual , staminate and pistillate on same plants or on different plants, often with rudiments of opposite type, or bisexual , actinomorphic , rarely slightly zygomorphic; perianth epigynous , free , mostly 6-parted, then differentiated into sepals and petals, rarely 3-parted, then petals absent in Thalassia and Halophila; stamens (0--) 2--many in 1 or more whorls (inner often staminodial), epigynous, distinct or ± connate ; pollen spheric, in monads or tetrads or in slender chains; ovary 0--1, if present, inferior, 2--6[--16]-carpellate, 1-locular or falsely 6--9-locular; placentation parietal . Fruits berrylike. Seeds many, fusiform , ellipsoid , ovoid , or spheric; seed coat glabrous, papillose , or echinate .

Genera 17, species ca. 76 (10 genera, 14 species in the flora ) : nearly worldwide.

Hydrocharitaceae, like other members of the Alismatidae, have one or more (fewer than 20) scales (intravaginal squamules ) in the axils of their leaves. These scales (or hairs in some taxa) secrete mucilage and are without any venation . The structures are often referred to as "squamulae intravaginales" or "intravaginal scales" in the literature.[1]
