Flora of North America species comparison

basal;

petiole (0.5–)1–3 cm;

blade oblanceolate, (0.5–)1–5 × (0.3–)0.4–0.7(–1) cm, villous.

basal;

petiole 0.5–3 cm;

blade elliptic to oblong, 0.5–2 × 0.2–0.6 cm, thinly pubescent adaxially, tomentose abaxially.

rather dense with secondary branches suppressed, greenish to reddish;

bracts 2, similar to proximal leaf blades only reduced, short-petiolate, becoming narrowly elliptic to linear-lanceolate and aciculate at distal nodes, acerose, 0.5–5 cm × 2–7 mm, awns 0.5–1.2 mm.

mostly flat-topped, openly branched, greenish to reddish;

bracts persistent, 2, usually leaflike at proximal nodes and similar to leaf blades, short-petiolate, oblong, 0.5–1.2 cm × 2–4 mm, sessile, reduced and scalelike at distal nodes, linear, acicular, often acerose, 0.1–0.5 cm × 0.5–1 mm, awns straight, 0.5–1 mm.

1, greenish, cylindric, often ventricose basally, 1–3 mm, without scarious margins or if so then white to pink, thin, and restricted to basal portions of teeth, corrugate, villous abaxially;

teeth spreading, equal, 0.5–2 mm;

awns uncinate or straight with longer ones 2–3 mm and anterior one mostly 2.5–3 mm, these alternating with shorter 1–1.5(–1.7) mm ones.

in dense terminal clusters with 1 at node of dichotomies, reddish, cylindric, not ventricose, 2–2.5 mm, corrugate, without scarious or membranous margins, thinly pubescent with stoutish, recurved hairs;

teeth spreading, unequal, 0.3–0.8(–1) mm, with 3 longer ones more erect than 3 shorter and less-prominent ones;

awns uncinate, 0.3–0.5 mm.

included to slightly exserted;

perianth bicolored with floral tube white and tepals white to rose, cylindric, 2–3 mm, pubescent abaxially;

tepals connate less than 1/4 their length, monomorphic, oblong, truncate to 3-lobed and distinctly cuspidate apically;

stamens 9, slightly exserted;

filaments distinct, 2–3 mm, glabrous;

anthers cream to rose, narrowly oblong, 0.3–0.4 mm.

exserted;

perianth white or rose or red with white lobes, cylindric, 2.5–3 mm, glabrous except for few scattered hairs ca. midlength along midrib abaxially;

tepals connate 1/2 their length, monomorphic to slightly dimorphic, oblong, rounded apically, those of outer whorl usually slightly broader and longer than those of inner whorl;

stamens 6, included;

filaments distinct, 1.5–2 mm, glabrous;

anthers pink to red, oblong, 0.3–0.4 mm.

light brown, globose-lenticular, 2–3 mm.

brown, lenticular, 2.5–3 mm.
