S. tenuifolia Willd. var. hispida (Pursh) Fernald

Map 2001

Stems 40–100 cm long, glabrous on the sides, sparsely pubescent with relatively long, spreading to somewhat downward-angled, sometimes pustular-based hairs along the angles, usually glabrous at the nodes. Leaves sessile or short-petiolate, the petioles to 10 mm long. Leaf blades 3–12 cm long, lanceolate to oblong, often narrowly so, angled to rounded or rarely shallowly cordate at the base, angled or more commonly tapered to a sharply pointed tip, the upper surface moderately pubescent with loosely spreading hairs, the undersurface sparsely short-hairy. Inflorescences interrupted or more commonly loosely continuous spikes, the nodes well-spaced to somewhat crowded. Calyces 5–9 mm long, the tube sparsely to moderately pubescent with spreading, sometimes pustular-based hairs, sometimes also with minute, gland-tipped hairs, the lobes 3.0–4.5 mm long, moderately pubescent with spreading, sometimes pustular-based hairs, sometimes only along the margins. Corollas 12–14 mm long. 2n=68. June–September.

Scattered, mostly in the eastern half of the state, apparently absent from the Unglaciated Plains Division and most of the Ozarks (northeastern U.S. west to North Dakota and Missouri, south locally to Georgia; Canada). Bottomland forests, banks of streams, margins of ponds and lakes, bottomland prairies, and marshes; also ditches, railroads, roadsides, and moist, disturbed areas.
