Flora of North America species comparison

several, simple proximal to inflorescence, 30–80 cm, puberulent, becoming subglabrous near base.

1–several, straggling to erect, sometimes decumbent at base, simple or much-branched distally, 20–120 cm, puberulent or scabrous-pubescent, sometimes retrorse, often glandular distally, becoming glabrate proximally.

withering proximally, in whorls of 4, ± sessile to short-petiolate, largest in mid-stem region;

blade lanceolate to ovate-lanceolate, 3–10 cm × 4–40 mm, apex acuminate, puberulent on both surfaces, sparsely so adaxially.

sessile or narrowed at base into pseudopetiole, blade pubescent on both surfaces;

proximal with blade lanceolate and oblanceolate, broadest distally or distal often reduced, cauline longest near mid stem, blade linear to lanceolate or elliptic, 1.5–10 cm × 2–30 mm.

paniculate, open, bracteate, bracteolate, branches elongate, puberulent;

bracts and bracteoles linear-lanceolate, 2–15 mm.

from 1-flowered to simple dichotomy to compound and 3–5–many-flowered with elongate branches;

bracts small, linear-lanceolate, or resembling leaves.

straight, often with 1 or 2 pairs of bracteoles, slender, 1/2–3 times calyx, glabrous or scabrous-puberulous.

elongate, much exceeding calyx.

calyx obscurely 10-veined, broadly campanulate, becoming obtriangular in fruit, 7–11 × 6–10 mm, herbaceous, margins dentate, very narrow, membranous, sparsely puberulent, lobes broadly triangular, 2–3 mm;

corolla white, ca. 2 times longer than calyx, limb obtriangular, narrowed into claw, divided ca. 1/2 its length into 4–12 lobes, appendages absent;

stamens equaling petals;

styles 3, longer than petals.

calyx green, 10-veined, broadly tubular, 12–25 × 4–8 mm in flower, narrower towards base, middle broadening to 6–13 mm in fruit, narrower at both ends, pubescent, glandular, lobes lanceolate, 2.5–5 mm, margins membranous or not, apex ± obtuse;

corolla scarlet, clawed, claw equaling or longer than calyx, limb lobed, often deeply so, lobes 4–6, linear, lanceolate, or oblong, small lateral teeth may be present, 6–15 mm, appendages inconspicuous, 1–2 mm, dentate;

stamens longer than corolla claw but shorter than lobes;

stigmas 3, equaling corolla.

globose, opening by 3 broadly triangular teeth;

carpophore 2–3 mm.

oblong to ovoid or broadly tubular, equaling calyx, opening by 6 ascending teeth;

carpophore 2–4 mm.
