Typha angustifolia L.
NATIVE OR NATURALIZED
Habit: Plant 15--30 dm. Stem: 2--3 mm diam at inflorescence. Leaf: sheath-tip lobes ear-like, membranous, disintegrating with age; widest fresh blades 4--15 mm wide, dry 3--8 mm wide, glands 0. Inflorescence: naked stem between staminate, pistillate flowers 1--12 cm; staminate scales hair- to strap-like, brown; pistillate spike dark brown; compound pedicels short, +- blunt, peg-like in fruit, +- 0.5 mm; pistillate bractlets blunt, length = pistillate flower hairs, width >= stigma width, dark brown, generally darker than stigma. Flower: pollen grains single; stigma linear, +- white in flower, light brown in age; sterile ovary green, drying brown, visible at spike surface, reaching pistil hair tips; pistil hair tips swollen, uniformly brown. Chromosomes: 2n=30.
Ecology: Nutrient-rich freshwater to brackish marshes, wet disturbed places; Elevation: < 2000 m. Bioregional Distribution: NW, SN, GV, CCo, SnFrB, SCo; Distribution Outside California: to southern British Columbia, central and eastern temperate North America, Eurasia. Flowering Time: May--Aug Note: Possibly naturalized in California.
Unabridged Note: If recognized taxonomically, hybrids with Typha latifolia assignable to Typha × glauca Godr. There is strong evidence that Typha angustifolia was introduced from Europe to the Atlantic Coast in colonial times; it has been known from California since at least 1909; it and Typha × glauca are serious invasive weeds in eastern North America.
