Broadleaf Cattail - Typha latifolia
MNPS Threat Rank
Stems 1–2 m. Leaves glaucous, 6–18 mm wide. Inflorescence: male spike 7–15 × 1–2 cm; contiguous or separated from the female spike 7–15 × 1–3 cm. Flowers: stigma lanceolate black at the tip; pollen grains shed in tetrads (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX)
Typha latifolia, broad-leaved cattail, is distinguished from T. angustifolia;, narrow-leaved cattail, by the relative width of the leaf and the position of the staminate and pistillate portions of the spadix (heads). Typha latifolia has 6-23 mm wide leaves that are flat, sheathing, and pale grayish-green in color. Typha angustifolia has 3-8 mm wide leaves that are full green and somewhat convex on back (Agricultural Rea. Service 1971). In T. latifolia the staminate and pistillate heads are contiguous or nearly so, whereas in T. angustifolia the heads are separated by approximately 3 cm.
Cattail fruits differ among the two major species. Typha angustifolia fruits are about 5-8 mm long with hairs arising above the middle. Typha latifolia fruits are about 1 cm long with hairs arising near the base (Agricultural Rea. Service 1971).
Circumboreal south to all of temperate North America (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).
