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.

erect, from decumbent base, 5–30 cm, sparsely to densely pubescent, hairs spreading, straight, often glandular; small axillary tufts of leaves usually absent.

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.

subsessile;

blade broadly elliptic to obovate or rotund, larger blades in mid-stem region, 5–22 × 2–8 mm, apex round and obtuse, rarely broadly acute, pubescence ciliate and strigose, hairs long and eglandular, mixed with shorter eglandular hairs, colorless to somewhat fuscous;

proximal leaves not strongly marcescent, blade oblanceolate, often broadly so, spatulate.

lax, 3–50-flowered cymes;

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

1–3-flowered, lax cymes, with patent, multicellular, long, glandular hairs;

proximal bracts broadly lanceolate, pubescence as leaves;

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

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

± straight or somewhat curved at apex, 5–45 mm, 1–4 times as long as sepals (rarely longer), pubescence long and glandular.

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 narrowly lanceolate, 8–11 mm, margins narrow, apex acuminate, hairs ascending, long, glandular and eglandular;

petals 12–18 mm, 1–2 times as long as sepals, apex 2-fid;

stamens 10;

styles 5.

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

teeth 10, erect, margins convolute.

broadly conic, straight or almost so, 14–18 mm, 1.5–2 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.

red-brown, 1.1–1.3 mm diam., tuberculate;

tubercles acute;

testa not inflated, closely enclosing seed.
