Flora of North America species comparison

erect or ascending, branched, 5–45 cm, hairy, glandular at least distally, rarely eglandular; small axillary tufts of leaves absent.

flowering stems usually erect, 10–25 cm, glabrous to sparsely pubescent proximally, more densely so in mid and distal stem, hairs patent to slightly deflexed, multicellular, glandular and eglandular;

internodes usually equaling or exceeding leaves; nonflowering shoots present; small axillary tufts of leaves absent.

not marcescent, ± sessile;

blade 5–20(–30) × 2–8(–15) mm, apex apiculate, covered with spreading, white, long hairs;

basal with blade oblanceolate or obovate, narrowed proximally, sometimes spatulate;

cauline with blade broadly ovate or elliptic-ovate.

sessile (flowering shoots) or petiolate (proximal stems and nonflowering shoots); flowering shoots with blade lanceolate, 5–20 × 2–5 mm, not succulent, apex ± acute, pubescent;

proximal stem and nonflowering shoots with blade oblanceolate often spatulate, not succulent, apex obtuse, ± pubescent on both surfaces (rarely subglabrous), with straight, strigose hairs or cilia, hairs pale, fuscous, mostly eglandular.

3–50-flowered, aggregated into dense, cymose clusters or in more-open dichasia;

bracts: proximal herbaceous, distal lanceolate, apex acute, with long, mainly eglandular hairs.

open, dichotomous, (1–)3–10-flowered cymes;

bracts lanceolate, distal with scarious margins, proximal herbaceous and foliaceous, pubescence glandular and eglandular.

erect to spreading, often arcuate distally, 0.1–5 mm, shorter than capsule, glandular-pubescent.

erect, angled at base of calyx in fruit, 8–55 mm, 1–5 times as long as capsule, densely pubescent with patent glandular and eglandular hairs.

sepals green, rarely dark-red tipped, lanceolate, 4–5 mm, margins narrow, apex very acute, usually with glandular hairs as well as long white hairs usually extending beyond apex;

petals oblanceolate, 3–5 mm, rarely absent, usually shorter than sepals, apex deeply 2-fid;

stamens 10;

styles 5.

sepals lanceolate to lance-elliptic, 3–7 mm, margins broad, apex ± acute, densely glandular-pubescent;
