Flora of North America species comparison

erect or ascending, branching near base, 2–12 cm, covered with glandular and eglandular hairs; small axillary tufts of leaves usually 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, sessile;

blade 5–15 × 3–6 mm, hairy;

basal with blades oblanceolate, spatulate, petiolelike, apex obtuse;

cauline with blades lanceolate, elliptic, or ovate, apex acute to obtuse.

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.

lax, 3–15-flowered (rarely more) cymes;

bracts lanceolate: proximal usually foliaceous, distal smaller, usually with narrow, scarious margins and apex, glandular-pubescent.

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

bracts herbaceous, lanceolate, glandular-pubescent.

erect, curved distally, 3–8(–10) mm, longer than capsule, glandular-pubescent.

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, sometimes red tipped, oblong-lanceolate, 4–5 mm, margins narrow, apex acute, pubescent, hairs short, stiff, glandular, not projecting beyond scarious, glabrous apex;

petals white or purple-tinged, with branching veins, oblanceolate, ca. 5 mm, ± equaling sepals, apex 2-fid for ca. 1/4 length;

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;

petals oblanceolate, sometimes absent, 3–6(–8) mm, shorter to 1.5 times longer than sepals, apex 2-fid;

stamens 10;

styles 5.

narrowly cylindric, slightly curved upward, 6–9 mm, ca. 2 times as long as sepals;

teeth 10, erect, margins convolute.

cylindric, curved, (9–)10–12(–13) mm, 2–3 times as long as sepals;

teeth 10, erect, margins convolute.

dark brown, deltoid, 0.6–0.7 mm, tuberculate;

testa not inflated.

golden brown, 0.5–0.8 mm diam., shallowly tuberculate;

testa not inflated.
