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.

few to many, erect or ascending, much-branched with many short, leafy axillary shoots, hairs recurved to retrorse, short, ± stiff, eglandular, often with some spreading, long 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.

green, linear-lanceolate to lanceolate, 1–3.5 cm, not fleshy, margins plane, sometimes ± wavy, flat to involute, (0–)3–7-lobed, apex acute to obtuse;

lateral lobes spreading, linear, much shorter and narrower than terminal lobe, 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.

3–17 × 2–7.5 cm;

bracts green throughout, sometimes distalmost proximally green, distally red or red-orange on apices, lanceolate or broadly lanceolate, (0–)3–5-lobed;

lobes spreading, linear or narrowly lanceolate, short, arising near or below mid length, central lobe apex obtuse to rounded, lateral ones acute.

± 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.

slightly curved, (24–)27–43 mm;

tube 9–20 mm;

beak longer than calyx, exserted through abaxial cleft, adaxially green to yellowish, 22–39 mm;

abaxial lip deep green, inflated, tight, 1–2.5 mm, 5–10% as long as beak;

teeth often spreading, green or white, 0.5–1.6 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.

proximal 1/3 green, distal 2/3 red to pale red-orange, rarely yellow, (17–)25–35(–40) mm;

abaxial clefts 14–29 mm, 67–75% of calyx length, adaxial 2.5–7.3 mm, 5–15% of calyx length, deeper than laterals, lateral 0–0.3(–2) mm, 0–5% of calyx length;

lobes broadly triangular, entire or shallowly cleft, segments, if present, often differing in length, apex acute, obtuse, or rounded.
