Flora of North America species comparison

flowering stems erect from decumbent base, branched proximally, 10–45 cm, softly pubescent, eglandular with straight hairs; nonflowering shoots, when present, produced proximally, decumbent, rooting at nodes, branched, 5–20 cm, often subglabrous with alternating lines of eglandular hairs; small axillary tufts of leaves usually absent.

usually erect, simple or several-branched, from branched caudex, rarely bushy, 6–40 cm, glandular-pilose, hairs in mid-stem region equaling or longer than stem diam.; small axillary tufts of leaves absent Leaves sessile;

blade 7–25 × 1–6 mm;

basal rosette absent or poorly developed and withering when young;

proximal with blade oblanceolate to spatulate;

distal with blade linear-lanceolate or lanceolate to narrowly elliptic, apex usually acute, rarely obtuse, glandular-pilose.

not marcescent;

blade 10–25(–40) × 3–8(–12) mm, densely covered with patent to ascending, colorless, long, eglandular hairs;

leaves of flowering shoots in distant pairs, sessile, blade elliptic to ovate-oblong, apex subacute;

leaves of sterile shoots pseudopetiolate, often spatulate, blade oblanceolate, apex obtuse.

lax, 3–50-flowered cymes;

bracts lanceolate, reduced, herbaceous, eglandular-pubescent, distal often with narrow, scarious margins.

diffuse, elongate, usually with single dichotomy at or below mid stem, 3–18-flowered cymes, glandular-pubescent, flowers widely and racemosely spaced in axils of paired bracts along each branch;

bracts herbaceous, lanceolate, glandular-pubescent.

somewhat curved distally, 2–10(–20) mm, longer than sepals, densely pubescent with patent, eglandular, rarely glandular hairs.

sharply curved just below capsule, 2–10(–15) mm, shorter than to 2 times as long as capsule, with dense, patent, glandular pubescence.

sepals ovate-lanceolate, 5–7 mm, margins narrow, apex acute, scarious, pubescent with eglandular, rarely glandular, hairs;

petals oblanceolate, 1–1.5 times as long as sepals, apex deeply 2-fid;

stamens 10, occasionally 5;

styles 5.

sepals lanceolate, 3–5 mm, apex acute, glandular-hispid, hairs not extending beyond sepal tips, inner sepals with broad margins, outer sepals with very narrow margins;

petals oblanceolate, 2–3 mm, shorter than sepals, apex 2-fid ca. 1/4 of length;

stamens 5;

styles 5.

narrowly cylindric, curved, 9–17 mm, ca. 2 times sepals;

teeth 10, erect, margins convolute.

narrowly cylindric, curved, 7–8.5 mm, ca. 2 times as long as sepals;

teeth 10, erect, margins convolute.

reddish brown, 0.4–1.2 mm, bluntly tuberculate;

testa not inflated, tightly enclosing seed.
