Flora of North America species comparison

sometimes disarticulating at each node.

basal;

petiole (0.5–)1–3(–4) cm;

blade oblanceolate, (0.5–)1–5(–7) × (0.3–)0.4–0.7(–1) cm, villous.

blades linear to lanceolate, obovate, round, or spatulate.

rather dense with secondary branches suppressed, grayish;

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

bracts mostly 2, opposite, scalelike or if leaflike then similar to basal leaves only reduced, occasionally deciduous in early anthesis, with or without awns.

1, grayish, cylindric, often ventricose basally, 2–2.5(–3) mm, with distinct, white to pink or purple, scarious margins extending nearly full length of awn, corrugate, villous abaxially;

teeth spreading, equal, 0.5–1.5 mm;

awns uncinate with longer ones 2–3 mm and alternating with shorter (1–1.5 mm) ones.

cylindric to narrowly turbinate, campanulate, or urceolate, occasionally ventricose basally, 3-,5-, or 6-toothed, with or without membranous or scarious margins;

teeth erect to spreading or divergent, connate at least 1/2 their length, typically shallow, mostly unequal, with alternating long and short awns, often with anterior one longest.

exserted;

perianth bicolored with floral tube white and tepals white to rose, cylindric, 2–3.5 mm, pubescent abaxially;

tepals connate less than 1/4 their length, monomorphic, obovate to oblong, acute to truncate and erose apically;

stamens 9, slightly exserted;

filaments distinct, 2–3 mm, glabrous;

anthers cream to rose, ovate, 0.3–0.4 mm.

1(–2), white to pink or rose, maroon or purple, or yellow, thinly pubescent at least along midribs abaxially;

stamens 3–9;

filaments adnate at base of floral tube or faucially;

filaments sometimes connate into short tube.

dark brown, globose-lenticular, 2–2.5 mm.

brown, lenticular or globose-lenticular, or 3-gonous.

embryo straight or rarely curved.
