Treatment appears in FNA Volume 10.

Stems glabrous or sparsely villous. Leaves alternate or fas­cicled; stipules symmetrical; petioles of basal leaves 0.3–0.8 cm, those of distal leaves 0.2–2.5 cm; blade 0.8–4 (–8.5) cm, apex sometimes glandular-mucronate, surfaces shiny, glabrous, rarely ciliate or minutely pellucid-punctate. Flowers: anthers on short filaments 0.5–1.1 mm, those on long filaments 0.8–1.2 mm; ovary 6–14 mm, apex truncate, glabrous or with scattered hairs, stigma usually as long as anthers, rarely exserted beyond them. Capsules 10–17 (–25) × 2–3 mm, pedicel 10–35 mm. Seeds 7–14 per locule. 2n = 16.


Phenology: Flowering summer–early fall.
Habitat: Wet places, along slow-moving rivers, streams, canals, ditches, often growing into main channels as aquatic weeds.
Elevation: 0–900[–3000] m.

Distribution

Ariz., Calif., N.Mex., Oreg., Tex., Mexico, West Indies (Cuba), Central America, South America, Pacific Islands (Galapagos Islands), elsewhere in Pacific Islands (Society Islands), Australia
