Erect shoots 150--400 cm, not glaucous; flowering shoots 1--2 cm thick in middle; stems 3--4 mm thick near spike. Leaves: sheath sides membranous, margin broadly clear, summit tapered to blade or with persistent, membranous auricles; mucilage glands at sheath-blade transition orange-brown, numerous on entire sheath and proximal 1--10 cm of blade; widest blades on shoot 6--18 mm wide when fresh, 5--15 mm when dry; distal blade about equaling inflorescence. Inflorescences: staminate spike separated from pistillate by (0--)1--8 cm of naked axis, ca. 1.4 X longer than pistillate, 1 cm thick at anthesis; staminate scales straw-colored to mostly bright orange-brown, variable in same spike, linear to cuneate, often laciniate distally, to 3--4 0.3 mm; pistillate spikes in flower when fresh bright cinnamon-brown with whitish stigmas (drying brownish), later orange- (to medium) brown, in fruit generally paler as stigmas and often bracteole blades wear off, ca. 6--35 cm 5--6 mm in flower, 15--25 mm in fruit; compound pedicels in fruit peg-like, ca. 0.6--0.9 mm; pistillate bracteole blades forming spike surface before flowering, later slightly exceeded by stigmas and slightly exceeding pistil hairs, straw-colored to bright orange-brown, much paler than to nearly same color as stigmas, irregularly narrowly to broadly spatulate or lanceolate, 0.8 0.1--0.3 mm, mostly wider than stigmas, apex variable in same inflorescence or different plants, acute or acuminate. Staminate flowers 5 mm; anthers 2--2.5 mm, thecae yellow, apex bright orange-brown; pollen in single grains. Pistillate flowers 2 mm in flower, 8--9 mm in fruit; pistil-hair tips straw-colored to orange-brown in mass, usually with 1 subapical bright orange-brown, generally enlarged cell; stigmas often deciduous in fruit, in flower erect, elongating, bending to form surface mat, white in flower when fresh, later bright orange-brown, narrowly linear-lanceolate, ca. 1 0.1 mm; carpodia slightly exceeded by pistil hairs, usually evident at fruiting spike surface, straw-colored, orange-spotted, apex broadly rounded. 2n = 30. Flowering spring--summer. Often in brackish water or wet soil; 0--2000 m; Ala., Ariz., Ark., Calif., Colo., Del., Fla., Ga., Ill., Kans., Ky., La., Md., Miss., Mo., Nebr., Nev., N.Mex., N.C., Okla., S.C., Tex., Utah, Va., Wyo.; Mexico; West Indies; Central America; South America; West Indies; Eurasia; Africa; Pacific Islands (New Zealand); Australia. Typha domingensis aggressively invades and forms nearly pure stands in brackish or nutrient-enriched wetlands in the Florida Everglades and elsewhere. It is established but does not mature fruits on the cold coast of northern California. There are specimens of putative hybrids with T. angustifolia beyond the main range of T. domingensis, in southeastern and northwestern Nebraska and southeastern Kentucky, and with T. latifolia in southeastern Nebraska. Vegetative T. domingensis or hybrids occur on the Atlantic Coast north as far as Delaware. (S. G. Smith, unpublished). The northern Illinois locality is a power plant cooling pond. The Wyoming record is from a hot spring and may be a hybrid with T. latifolia. Typha domingensis probably should be treated as a highly variable pantropic and warm temperate species, occurring to 40º E north and south latitude worldwide, and needing study to determine infraspecific taxa and delimitation from related species (B. G. Briggs and L. A. S. Johnson and B. G. Briggs 1968; S. G. Smith 1987). For hybrids see also genus and key. Other References (plus corrections and additions) missing from this file.

Plant: Tall perennial graminoid Leaves: 6-9(-12), light yellowish green, 6-12(-15) mm wide, flat but moderately convex on the back, the sheath cylindrical and open at the throat, with scarious margins tapering to the blade INFLORESCENCE: (including stems) 2.5-4 m tall, about as long as the leaves, with the pistillate and staminate portions separated by 1-4 cm; staminate spikes 20-40 cm long, the pistillate spikes light brown, 15-25 cm long, 1.5-2.5 cm thick Flowers: STAMINATE FLOWERS: pollen golden-yellow, in monads. PISTILLATE FLOWERS light brown, with obovate to oblanceolate, translucent to light brown bracts exceeding the stipe hairs, arranged on stout "compound pedicels" 0.5-0.8 mm long, these with numerous hair-like appendages, the stigma light brown, linear; surface of the main stem axis minutely bristly Fruit: ellipsoid, 0.8-1 mm long, long stalked, minute nutlets, dry, tardily dehiscent, buoyant; SEEDS albuminous, striate, with mealy endosperm Misc: In brackish or fresh marshes, streams, rivers, ponds and lakes; 300-1800 m (1000-6000 ft); Mar-Nov (fr. Jun-Jan) References: J.C. Hickman, ed. The Jepson Manual.ASU specimens. Ricketson, Jon. 2001. Sparganiaceae. J. Ariz. - Nev. Acad. Sci. Volume 33(1).
Perennial colony-forming herb 1.5 - 4 m tall Stem: erect, unbranched, 3 - 4 mm thick near the inflorescence. Leaves: sheathed at the base, long and narrow with the uppermost blade about equalling the inflorescence, 6 - 18 mm wide when fresh and 5 - 15 mm wide when dry, loosely twisted. The intersection of the sheath and blade is membranous and sometimes has persistent ear-shaped appendages (auricles). Inflorescence: a dense cylindric terminal spike with the male part separated above the female part by 1 - 8 cm (rarely touching). The male part is about 1.4 times longer than the female part, about 1 cm thick, with straw-colored to mostly bright orangish brown scales that are 3 - 4 mm long, to 0.3 mm wide, linear to wedge-shaped and often deeply cut into slender segments near the tip. Female part bright cinnamon-brown with whitish stigmas drying brown, becoming paler in fruit, 6 - 35 cm long, 5 - 6 mm wide, becoming 1.3 - 2.5 cm wide in fruit. Fruit: a tiny dry follicle borne on a slender stalk, the stalk having many long white hairs usually with a large brown cell near the tip, each follicle single-seeded. Male flowers: 5 mm long, with 2 - 2.5 mm long anthers that are yellow with a bright orangish brown tip and solitary pollen. Female flowers: subtended by spoon- to lance-shaped bracts with a pointed tip, 2 mm long. Straw-colored to orangish brown pistil-hair tips often have an enlarged bright orangish brown cell near the tip, and the lance-linear stigmas are white but dry to bright orangish brown before falling in fruit.
Similar species: Typha angustifolia has dark brown fruiting spikes and rounded female flower bract tips. Typha latifolia has inflorescences with the male and female parts usually touching each other, pollen grains in clusters of four, and female flowers with spoon- to egg-shaped stigmas but without bracts.
Flowering: June to October
Habitat and ecology: Native to the southern United States. The only Chicago Region population of this species grows at a power plant cooling pond in Will County.
Occurence in the Chicago region: non-native
Etymology: Typha comes from the word typhe, the old Greek name for cat-tail. Domingensis means "of Santo Domingo."
Much like no. 2 [Typha angustifolia L.], but taller (often 2.5-4 m) and with more numerous lvs, these thicker, up to 15 mm wide, often some or all of them exauriculate; pistillate portion of the spike light brown, 1.3-2.5 cm thick at maturity, separated from the staminate portion by up to 8 cm, rarely contiguous with it; pistillate bracteoles acuminate; sterile pistillate fls narrowly cuneate at the tip; hairs subtending the fr white with usually a single large brown cell near the tip; pollen in monads; 2n=30. Pantrop., extending n. in coastal marshes to Md. and Del., and n. inland to Nebr. and Utah.

Common Name: southern cattail Duration: Perennial Nativity: Native Lifeform: Unknown General: Tall monoecious herb with extensively creeping rhizome, erect flowering stem 2.5-4 m tall, cylindric and pithy. Vegetative: Leaves alternate, 6-9, light yellowish green, 6-12 mm wide, moderately convex on back, sheath cylindric and open at throat, scarious margins tapering to blade. Inflorescence: Erect spike with pistillate and staminate portions separated by 1-4 cm, staminate spike 20-40 cm long on bottom, pistillate spikes light brown, 15-25 cm long, 1.5-2.5 cm thick; flowers minute, sessile and naked, pistillate flowers light brown and less than 1 mm long, surface of main stem minutely bristly; fruit ellipsoid achenes about 1 mm long. Ecology: Found in brackish to fresh marshes and streams, rivers, lakes and ponds from 1,000-6,000 ft (305-1829 m); flowers March-November. Notes: Far more common and widespread, this species is told apart by the interrupted spike and the more narrow leaves at 6-12 mm wide, which are moderately convex on back, while the leaves of the plant are more yellowish green rather than pale green, wider, and flat in T. latifolia. Ethnobotany: Stalks, roots, and seeds were eaten as food, the latter winnowed and toasted and made into meal, used for thatch in houses, weirs, sandals, and clothing. Etymology: Typha comes from the Greek word for the plant, while domingensis is thought to come from Santo Domingo. Synonyms: Typha angustata Editor: SBuckley, 2010
