Flora of North America species comparison

erect, sparingly branched proximally, slender, 15–35 cm, sparsely glandular-pilose; small axillary tufts of leaves absent.

erect, simple or branched at or near base, sometimes with straggling, nonflowering basal shoots, 10–50 cm, softly pubescent, often with a few long, flexuous, woolly hairs at proximal nodes, glandular and somewhat viscid distally; small axillary tufts of leaves usually absent.

not marcescent;

proximal blades broadly spatulate-petiolate, 8–55 × 3–16 mm, apex acute or obtuse, sometimes short-acuminate, softly pilose;

cauline few, sessile, blade linear-lanceolate to narrowly oblanceolate, 7–30 mm, apex acute, pilose.

marcescent or not, sessile;

blade oblanceolate to spatulate in proximal leaves, becoming lanceolate to linear-lanceolate in distal leaves, occasionally elliptic, 10–60 × 3–15 mm, apex acuminate to acute, softly pubescent and glandular, sometimes tomentose.

very open and loose, 2–9(–25)-flowered cymes;

bracts narrowly lanceolate, pilose.

rather open, 3–21(–40)-flowered cymes, ultimately widely branched;

bracts herbaceous, lanceolate, glandular-pubescent.

straight, becoming sharply deflexed at base, slender, 5–20 mm, elongating in fruit, 1.5–4 times as long as sepals, glandular-pilose.

ascending, sharply deflexed at apex in fruit, 5–20(–35) mm, usually 1–3 times as long as sepals in flower, elongating to 5 times as long as sepals in fruit, longer than capsules, glandular-pubescent and viscid.

sepals green, turning pale orange-brown in fruit, lanceolate to ovate, 3–6 mm, margins narrow, apex acute, with short, glandular pubescence;

petals oblanceolate, 5–8 mm, 1.5–2 times as long as sepals, apex 2-fid;

stamens 5;

styles 5.

sepals ovate-lanceolate, 4–6 mm, outer sepals herbaceous or with narrow margins, inner with margins ca. as wide as herbaceous center, apex broadly acute to obtuse, glandular-puberulent, hairs shorter than sepal tips;
