Flora of North America species comparison

simple, 5–15 cm, pubescent and viscid, with stipitate glands.

many, decumbent to erect, usually simple, 10–40 cm, woody, pilose and glandular (rarely eglandular proximally).

basal with blade 1-veined, oblanceolate, broadly spatulate, 1–4 cm × 2–8 mm, apex obtuse to acute, glandular-puberulent throughout, rarely subglabrous adaxially;

cauline in 3–6 pairs, sessile, reduced distally, blade lanceolate, narrowly elliptic, or oblanceolate, 2–4 cm × 2–8 mm, apex ± acute, glandular-puberulent throughout.

in 5–8 pairs, sessile but proximal ones narrowed into pseudopetiole, largest in mid-stem region, reduced proximally, scalelike at base, blade narrowly lanceolate to oblanceolate-elliptic or obovate, 2–6 cm × 3–20 mm, apex acute and acuminate, usually thick, leathery, densely puberulent and viscid-glandular or eglandular.

usually with solitary terminal flower, sometimes cymose, to 8-flowered, open.

cymose, open or congested, 3–15(–30)-flowered, sometimes compound, leafy.

erect or angled near tip with flowers slightly nodding, 1–3 times longer than calyx, glandular-puberulent, often densely so.

to 1(–1.5) cm, shortly pilose, viscid-glandular, flowers sometimes sessile.

calyx prominently 10-veined, campanulate, not contracted proximally around carpophore, 15–20 × 4–8 mm, papery, margins dentate, veins parallel, usually purple tinged, with pale commissures;

lobes ovate, 3–5 mm, glandular-puberulent, midrib triangular, margins purple tinged, broad, membranous, apex obtuse;

corolla bright pink, clawed, claw equaling calyx, broad and ligulate but abruptly contracted into limb, limb broadly cuneate, shallowly to deeply 2–4-lobed, 5–15 mm, lobes broad or narrow, appendages absent or to 2 mm, margins erose;

stamens slightly longer than corolla claw;

stigmas 3(–5), slightly longer than corolla claw.

calyx prominently 10-veined, tubular, clavate in fruit, constricted proximally around carpophore, (20–)25–30 × 4–7 mm, papery, densely glandular-puberulent, viscid, veins parallel, green, with pale commissures, lobes narrowly lanceolate, acuminate, 5–8 mm, herbaceous;

corolla pale greenish yellow to white, clawed, claw equaling calyx, ligulate, as broad as limb, limb 7–8 mm, deeply laciniate into 6 or more linear lobes, appendages oblong, laciniate, 2 mm;

stamens equaling calyx;

styles 3, exserted.

equaling calyx, opening by 6 (or 8 or 10) lanceolate teeth;

carpophore 1–2.5 mm.
