Flora of North America species comparison

flowering shoots often decumbent proximally, 5–20(–30) cm, glandular-pubescent distally, pilose-subglabrous, deflexed or spreading proximally;

non-flowering shoots present; small tufts of leaves present in axils of proximal leaves.

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, ± spatulate proximally;

blade linear-lanceolate to lanceolate or narrowly oblong, 4–30 × 0.5–6 mm, apex acute, rarely obtuse, subglabrous to softly pubescent, sometimes glandular.

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, 1–20-flowered cymes, pubescence short, glandular;

bracts lanceolate, margins narrow, scarious, glandular-pubescent.

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

bracts herbaceous, lanceolate, glandular-pubescent.

curved just below calyx, 5–30 mm, 1–6 times as long as sepals, 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 narrowly lanceolate to lance-elliptic, 3.5–7 mm, margins narrow, softly pubescent;

petals obovate, 7.5–12.5 mm, ca. 2 times as long as sepals, apex 2-fid;

stamens 10;

anthers 0.8–1.1 mm;

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.

cylindric, curved, 7.5–11.5 × 2.5–4 mm, (1–)1.5–2 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.

brown, 0.6–1.2 mm diam., tuberculate;

testa not inflated.

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

testa not inflated.
