Flora of North America species comparison

many, erect, unbranched or branched, sometimes with small, leafy axillary branches, hairs spreading, long, soft, mixed with shorter stipitate-glandular ones.

solitary or few, erect, from a basal rosette that usually persists into anthesis, unbranched or few-branched from mid stem, glabrate proximally, hairy distally, hairs moderately dense, spreading, long, soft, mixed with short stipitate-glandular ones.

green or purple-tinged, lanceolate to linear-oblong, 0.8–6.1 cm, not fleshy, margins wavy, involute, 0(–3)-lobed, apex rounded to acute;

lobes spreading-ascending, narrowly lanceolate, apex acute to acuminate.

basal forming a persistent rosette, often withered at anthesis, usually suffused to varying degrees with red, sometimes green, oblanceolate to oblong-oblanceolate, 2–6 cm, not fleshy, margins plane, flat, 0-lobed, apex obtuse to broadly rounded to sometimes acute or subtruncate;

cauline green, sometimes proximal suffused with red or purple, linear to linear-lanceolate or linear-oblanceolate, 1.1–6.5 cm, not fleshy, margins plane, flat, 0–3(–5)-lobed, apex usually acute, rarely obtuse;

lobes erect to ascending, narrowly oblong to linear or narrowly lanceolate, to 1.8 cm, apex acute.

3–34 × 1.5–3.5 cm;

flowers usually distichous, remote, except distalmost;

bracts proximally greenish, distally greenish, reddish, orange-red, or dull orange, rarely yellow, proximal bracts frequently greenish throughout, lanceolate to narrowly ovate or narrowly oblong-elliptic, 0(–3)-lobed, proximal wavy-margined;

lobes ascending, triangular, short, arising near apex, apex acute to obtuse.

(2–)4–24(–33) × 2–4 cm;

bracts proximally greenish, distally bright yellow, rarely light orange, proximal narrowly lanceolate, leaflike, distal oblong to broadly rounded-oblanceolate, continuing to grow after anthesis and becoming greener and more leaflike, lateral lobes, if present, growing even more than central lobe, 0–5-lobed;

lobes erect, triangular or lanceolate, sometimes linear, short or medium length, arising above mid length, proximal bract apex acute, distal rounded, rarely central lobe shallowly toothed.

± curved, 25–38 mm;

tube 14–18 mm;

beak and often abaxial lip exserted;

beak adaxially dull orange or dull red, rarely yellow, 14–19 mm;

abaxial lip slightly curved, green, red, whitish, or yellow, not inflated, 2–2.5 mm, 15% as long as beak;

teeth incurved, deep green to reddish, 1–1.5 mm.

straight or slightly curved, (15–)17–23 mm;

tube 8–11 mm;

abaxial lip rarely exserted, beak exserted;

beak adaxially green or yellow-green, 5–7 mm, margins yellow or yellow-green;

abaxial lip ascending, deep green, slightly inflated, 2–3 mm, 20–30% as long as beak, apex rounded;

teeth ascending, green, whitish, or yellow, 0.5–2 mm.

proximally whitish, green, or purple, distally colored as bracts, 9–18 mm;

abaxial clefts 6–6.5 mm, adaxial 7–9 mm, clefts 33+% of calyx length, deeper than laterals, lateral 1.5–4 mm, ca. 10% of calyx length;

lobes linear-lanceolate, apex acute.

proximally whitish or pale green, often aging purple, distally yellow, (13–)15–18 mm;

abaxial and adaxial clefts 4–7 mm, 40–50% of calyx length, deeper than laterals, lateral 0–0.2 mm, ca. 0% of calyx length;

lobes curved, oblong, apex rounded to truncate, sometimes emarginate.
