Habit: Plant 15--40 dm. Stem: 3--4 mm diam near inflorescence. Leaf: sheath-tip lobes ear-like, membranous or 0; widest fresh blades 6--18 mm wide, dry 5--15 mm wide, orange-brown gland-dotted adaxially on proximal 1--10 cm. Inflorescence: naked stem between staminate, pistillate flowers (0)1--8 cm; staminate scales generally strap-like, tips widened, generally irregularly dissected, yellow-brown; pistillate spike cinnamon to medium brown; compound pedicels short, +- blunt, peg-like in fruit, +- 0.7 mm; pistillate bractlets acute to acuminate, length > pistillate flower hairs, width >= stigma width, straw-colored to light brown, generally paler than stigma. Flower: pollen grains single; stigma linear, +- white in flower, medium- to yellow-brown in fruit; sterile ovary visible at spike surface, +- = pistil hair tips, straw-colored; pistil hair tips +- swollen, straw-colored with large orange-brown spot. Chromosomes: 2n=30.
Ecology: Nutrient-rich freshwater to brackish marshes, wet disturbed places; Elevation: < 1500 m. Bioregional Distribution: NCo, NCoRO, GV, CW, SW, GB, D; Distribution Outside California: to Alaska, eastern North America, worldwide warm temperate, tropics. Flowering Time: Jun--Jul Note: Very variable worldwide; needs study.
Unabridged Note: Plants in southern California are generally small, with lobed leaf-sheath tips. Occasional invasive weed in nutrient-rich places, e.g., in Florida Everglades, Costa Rica.
