Flora of North America species comparison

few to many, erect or strongly ascending, unbranched except for small, leafy axillary shoots, hairs spreading-reflexed to ± appressed, matted, long, soft, with much shorter stipitate-glandular ones, white-woolly.

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, linear to narrowly oblong or narrowly lanceolate, 1.3–5 cm, not fleshy, margins plane, sometimes wavy, involute, 3–7-lobed, apex acute;

lobes divergent, spreading-ascending, linear, 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.

5–22 × 1–4.5 cm;

bracts green to yellow-green throughout, or proximally green to yellow-green, distally yellow to sometimes pale yellow-orange, narrowly lanceolate to narrowly oblong or broadly lanceolate, 3(–7)-lobed;

lobes ascending to spreading, linear to oblong, medium length to long, arising near or below mid length, central lobe apex rounded to obtuse, lateral ones acute.

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.

straight or slightly curved, 14–22 mm;

tube 7–14 mm;

beak tip barely exserted from calyx;

beak adaxially greenish, 4–7 mm;

abaxial lip green to yellow, reduced, 1–4 mm, usually less than 67% as long as beak;

teeth erect, white to yellow, 1–2.5 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.

colored as bracts, 15–20 mm;

abaxial and adaxial clefts 5.5–8 mm, 30–50% of calyx length, ± deeper than laterals, sometimes appearing subequal in pressed specimens, lateral 5–6 mm, ca. 33% of calyx length;

lobes linear to narrowly lanceolate, sometimes expanded towards apices, 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.
