Typha latifolia
BROAD-LEAVED CATTAIL


Higher Taxonomy
Family: TyphaceaeView DescriptionDichotomous Key
Common Name: CATTAIL FAMILY
Habit: Perennial herb, glabrous; monoecious; rhizomes or stolons long; colonial, in wet soil to aquatic. Stem: aerial stem 1, +- cylindric. Leaf: basal and cauline, alternate, 2-ranked, spongy; sheath open; ligule 0; blade +- linear. Inflorescence: spike-like or of spheric, unisexual heads; staminate flowers or heads distal to pistillate ones. Flower: small, densely-packed. Staminate Flower: filaments fused proximally. Pistillate Flower: pistil 1, ovary superior, ovules 1--2(4). Fruit: follicle, splitting in water, or drupe-like.
Genera In Family: 2 genera, +- 32 species: worldwide.

Genus: TyphaView DescriptionDichotomous Key


Common Name: CATTAIL
Stem: erect, simple, cylindric, firm, air cavities 0. Leaf: ascending; blade C-shaped or planoconvex in ×-section proximally, flat distally, internal air cavities large; sheath-tip lobes present or not. Inflorescence: terminal; flowers 1000+; staminate flowers distal, mixed with many papery scales; pistillate flowers proximal, clustered on peg-like compound pedicels; bractlets many, thread-like with enlarged tips generally visible at spike surface, or 0. Staminate Flower: stamens 2--7 on slender stalk; filaments slender, generally deciduous in fruit. Pistillate Flower: stalk long-hairy, persistent; ovary chambers 1, style 1, persistent, stigma 1; many modified pistils with enlarged sterile ovary, style deciduous. Fruit: fusiform, thin-walled, yellow-brown, wind-dispersed.
Species In Genus: +- 15 species: boreal to tropics worldwide. Etymology: (Greek: to smoke or emit smoke) Note: Dissecting microscope ideal for Typha identification (flower structures small), which is complicated by hybridization.
Unabridged Note: Typha angustifolia × Typha latifolia (Typha × glauca Godr., pro sp.) and Typha domingensis × Typha latifolia (Typha × provincialis A. Camus) are generally highly sterile and intermediate between parents in most characters. Typha angustifolia × Typha domingensis are generally highly fertile, thus species boundaries are locally obscure. Hybrids involving 3 species are locally common. Although putative hybrids may produce no or few seeds they generally form long-persistent clones.

Typha latifolia L.
NATIVE
Habit: Plant 15--30 dm. Stem: 3--7 mm diam near inflorescence. Leaf: sheath tip lobes ear-like, papery, or 0; widest fresh blades 10--29 mm wide, dry 5--20 mm wide, glands 0. Inflorescence: naked stem between staminate, pistillate flowers generally 0(8) cm; staminate scales hair- to strap-like, colorless; pistillate spikes medium- to black- or red-brown, generally white-mottled in age; compound pedicels elongate, bristle-like in fruit, 1.5--3.5 mm; pistillate bractlets 0. Flower: pollen grains in 4s; stigma ovate to lance-ovate, green in flower, medium- to red- or black-brown in age; sterile ovary straw-colored, not visible at spike surface, < pistil hair tips. Chromosomes: 2n=30.
Ecology: Unpolluted to nutrient-rich freshwater (brackish) marshes; Elevation: < 2300 m. Bioregional Distribution: CA; Distribution Outside California: boreal North America to northern South America, Eurasia, northern Africa, Tasmania (introduced). Flowering Time: Jun--Jul

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
