Flora of North America species comparison

erect, branched, leafy, 20–60 cm, villose-tomentose, viscid-glandular.

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, connate proximally, sessile, largest in mid stem;

blade lanceolate, 3–7 cm × 5–15 mm, apex acute, glandular-tomentose throughout.

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.

open, leafy cymes, bracteate, viscid and glandular-tomentose, branches ascending, mostly floriferous, flowers terminal and at distal nodes;

bracts leaflike, 5–30 mm.

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

bracts small, linear-lanceolate, or resembling leaves.

shorter than calyx.

elongate, much exceeding calyx.

calyx obscurely 10-veined, tubular-campanulate, 10–15 × 4–5 mm in flower, becoming clavate and 15–20 × 6–8 mm in fruit, narrowed toward base around carpophore, herbaceous, viscid-pubescent, veins more distinct at base, without conspicuous pale commissures, lobes narrowly lanceolate, 3–6 mm, margins very narrow, membranous, apex blunt;

corolla greenish white, clawed, claw equaling calyx, widened distally, limb emarginate, 2 × 4 mm, appendages 4(–6), ca. 0.5 mm;

stamens equaling petals;

styles 3, 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 teeth;

carpophore 1.5–2.5 mm.

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

carpophore 2–4 mm.

yellowish brown, winged, reniform, ca. 2 mm, rugose;

wing broad, wrinkled.

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