Flora of North America species comparison

usually simple proximal to inflorescence, 30–50(–70) cm, puberulent and shortly stipitate-glandular, especially distally.

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.

2 per node, gradually reduced distally;

basal petiolate, blade oblanceolate, spatulate, 5–9 cm × 7–15 mm (including petiole), apex acute to obtuse, usually glabrous adaxially, sparsely pubescent abaxially;

cauline in 4–6 pairs, blade linear-lanceolate, 1–6(–8) cm × 2–6 mm, puberulent and shortly stipitate-glandular.

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.

thyrsate, 3–25-flowered, open, bracteate, pedunculate, stipitate-glandular, viscid;

bracts narrowly lanceolate, 2–25 mm, apex acuminate.

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

bracts small, linear-lanceolate, or resembling leaves.

ascending.

elongate, much exceeding calyx.

calyx prominently 10-veined, narrowly campanulate, umbilicate, somewhat clavate and constricted below middle around carpophore, 9–15 × 3–4 mm in flower, broadening to 7 mm in fruit, membranous, shortly stipitate-glandular, veins parallel, slender, tinged dark red, with pale commissures, lobes ovate-lanceolate, obtuse, 2–3 mm, margins scarious;

corolla creamy white, sometimes pink tinged, clawed, claw equaling calyx, glabrous, broadening only slightly into limb 3–8 mm, limb with 4–6 linear lobes, some splitting to 10 linear segments, appendages 4–6, linear, 1–1.5 mm, apex acute;

stamens ca. equaling petals;

filaments glabrous;

stigmas 3(–5), ca. equaling 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.

ellipsoid, slightly longer than calyx, opening by 6 (or 8 or 10) very brittle teeth;

carpophore 2–4 mm.

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

carpophore 2–4 mm.

brown, ± reniform, angular, glossy, shallowly tuberculate.

reddish brown, broadly reniform, 1.7–2.3 mm, sides tuberculate, margins papillate.
