Phragmites australis (Cav.) Steud.
Stem: 2--4 m. Leaf: blade generally 20--45 cm, 1--5 cm wide, margins scabrous, generally breaking at collar. Inflorescence: 15--50 cm, plume-like, oblong to obovoid, +- purple to +- white. Spikelet: 10--16 mm; lower glume 3--7 mm, upper glume 5--10 mm; florets 2--10. Chromosomes: 2n=36,44,46,48,49--52, 54,72,84,96.
Ecology: Pond and lake margins, sloughs, marshes; Elevation: generally < 1600 m. Bioregional Distribution: CA; Distribution Outside California: worldwide. Flowering Time: Jul--Nov Note: 3 different genetic lineages may occur in California: Phragmites australis subsp. americanus Saltonstall et al. (native), Phragmites australis subsp. berlandieri (E. Fourn.) Saltonstall & Hauber (native), and a 3rd naturalized entity whose taxonomic identity has yet to be determined [Saltonstall & Hauber 2007 J Bot Res Inst Texas 1:385--388].
Synonyms: Phragmites australis var. berlandieri (E. Fourn.) C.F. Reed; Phragmites berlandieri E. Fourn.; Phragmites communis Trin.; Phragmites communis var. berlandieri (E. Fourn.) Fernald
Unabridged Note: Perhaps most widely distributed of all seed pls. Recent work suggests that 3 different genetic lineages are present in California: Phragmites australis subsp. americanus Saltonstall et al. (native), Phragmites australis subsp. berlandieri (E. Fourn.) Saltonstall & Hauber (native), and a 3rd naturalized entity whose taxonomic identity has yet to be determined.
