Flora of North America species comparison

few to many, erect or ascending, unbranched, sometimes with inconspicuous, short, leafy axillary shoots, hairs spreading to erect, long, soft to stiff, mixed with shorter stipitate-glandular ones.

few to several, erect or ascending, usually decumbent at base, unbranched, sometimes branched, hairs spreading, short and long, soft, mostly glandular.

green, sometimes purple-tinged, margins sometimes red-brown, linear or narrowly to broadly lanceolate to narrowly oblong, oblanceolate, or ovate, 1–8.5 cm, not fleshy, margins plane or wavy, involute or flat, (0–)3–5(–7)-lobed, apex acute to rounded or acuminate;

lobes ascending, linear to narrowly lanceolate, much narrower than mid blade, apex acute to rounded.

green to deep purple, linear to broadly lanceolate, 1–3.5(–5) cm, not fleshy, margins plane or wavy, slightly involute, (0–)3–5-lobed, apex acuminate to acute, sometimes obtuse;

lateral lobes ascending-spreading, sometimes widely spreading, narrowly lanceolate to linear, mostly short, apex acute.

3–16(–30 in fruit) × 2–5 cm;

bracts proximally greenish to dull reddish purple, distally red to orange or yellow, sometimes crimson, scarlet, orange-red, red-orange, or burnt orange, often becoming paler and/or duller with age, lanceolate to oblong, ovate, or obovate, 3–5(–11)-lobed;

lobes spreading to ascending, linear to oblong or narrowly lanceolate, medium length or long, arising at or above mid length, central lobe apex obtuse to rounded or truncate, sometimes emarginate, truncate, or acute, lateral ones acute to obtuse.

2–7 × 1.5–3 cm;

bracts yellow-green, yellow, pinkish, pale reddish, or purple, sometimes distal margins pale white, oblong to broadly lanceolate to ovate, 0–5-lobed;

lobes spreading, linear to narrowly lanceolate, medium length to long, usually arising above mid length, rarely from below mid length, center lobe apex rounded to truncate, lateral ones acute to obtuse.

slightly curved, 17–38 mm;

tube 12–18 mm;

beak exserted, adaxially green, sometimes yellowish, rarely red-brown, 9–20 mm;

abaxial lip ascending, deep green, reduced, curved, 0.5–3 mm, to 10–33% length of beak;

teeth incurved, reduced, green, 0.5–1.2 mm.

straight or slightly curved, 17–22(–25) mm;

tube 11–16 mm; subequal to calyx or beak, sometimes abaxial lip, exserted;

beak adaxially yellow to green, 4–6(–7) mm;

abaxial lip green or yellow, reduced, often visible through front cleft, prominently pouched, thickened, 3–4(–5) mm, 50–67% as long as beak;

teeth erect, white, yellow, pink, or purple, 1.5–3 mm.

colored as bracts, sometimes with a yellow band proximal to red to orange apices, or ca. 1/2 yellowish and 1/2 reddish, 12–35 mm;

abaxial and adaxial clefts 7–12 mm, 33–65% of calyx length, deeper than laterals, lateral 2–7 mm, 15–30% of calyx length;

lobes triangular, linear, or oblong to lanceolate, apex acute or obtuse to rounded.

colored as bracts, sometimes strongly bicolored green or proximally whitish and distally as bract lobes, (12–)13–23(–25) mm;

abaxial and adaxial clefts 5–11 mm, 45–55% of calyx length, deeper than laterals, lateral (0.5–)1–3(–5) mm, 5–20% of calyx length;

lobes broadly triangular, apex obtuse to rounded, rarely acute.
