Flora of North America species comparison

several, erect to weakly ascending, often leaning on nearby shrubs, much-branched, often with short, leafy axillary shoots, hairs sparse, spreading, short or long, soft, branched or unbranched, eglandular.

several to many, ascending to erect, ± decumbent at base, branched or unbranched, sometimes with short, leafy axillary shoots, hairs spreading to ascending, long, soft to ± stiff, mixed with short-eglandular ones.

gray-green or green to purple to ± deep red, linear or linear-lanceolate, 2–5 cm, not fleshy, margins plane to ± wavy, flat or involute, 3–5(–7)-lobed, apex acuminate to acute;

lobes spreading-ascending, sometimes widely so, narrowly linear, apex acute or obtuse.

purple or green, linear-lanceolate to lanceolate, 3–5 cm, not fleshy, margins plane, partly involute, 3–5-lobed, apex acuminate, acute, or rounded;

lobes sometimes divergent, spreading-ascending, linear, apex obtuse to rounded.

3–20 × 0.5–1.5 cm;

bracts green throughout, sometimes tinged dull purple, proximal sometimes linear-lanceolate, distal or all bracts oblong, 3–5(–7)-lobed;

lobes spreading to ascending, linear to oblanceolate, short to long, proximal lobes arising near mid length, sometimes wavy-margined, central lobe apex rounded to truncate, lateral ones obtuse to rounded.

(2.5–)5–15 × 1.5–2 cm;

bracts proximally green to dull purplish, distally pale reddish purple, dull red, pale salmon, pale orange, or bright to pale yellow, oblong, 3(–5)-lobed;

lobes spreading to ascending, linear to oblanceolate, distal pair, if present, short and toothlike, short to long, arising at or above mid length, center lobe apex rounded to truncate, lateral lobes obtuse to rounded.

straight, 13–20 mm;

tube 5–7 mm;

beak short-exserted, sometimes shorter than abaxial calyx segments, adaxially yellow, rarely greenish, 7–10 mm;

abaxial lip pale green to yellowish, reduced, 0.5–1.5 mm, 7–17% as long as beak;

teeth reduced to apiculations, pale green to yellowish, 0.5–0.8 mm.

straight, 11–16 mm;

tube 10–13 mm;

beak included or tip exserted;

beak adaxially green, 4–5 mm;

abaxial lip deep green, reduced, with narrow pouches, 2.5–3 mm, 30–45% as long as beak;

teeth reduced to minute apiculations, dark green, 0.5–1 mm.

light green, cream, or light yellow, often appearing white from dense white-woolly pubescence, 10–18 mm;

abaxial clefts 5–6.5 mm, closed by intertwined hairs and appearing 2 mm deep, adaxial 2.2–4.2 mm, abaxial ca. 25% of calyx length, adaxial ca. 20% of calyx length, shallower (or appearing much shallower), than laterals, lateral 4.6–7.5 mm, ca. 50% of calyx length;

lobes: abaxial segments broad, paddle-shaped, 7 mm, inner surface of abaxial segments densely white-woolly, apex rounded to broadly obtuse, adaxial narrowly triangular, 5 mm, apex acute.

proximally usually whitish, distally colored as bracts, 13–18 mm;

abaxial and adaxial clefts 5–6(–9) mm, ca. 50% of calyx length, deeper than laterals, lateral 0.5–1.2 mm, ca. 18% of calyx length;

lobes ± hemispheric, segments often curved outwards, exposing corollas, apex rounded to obtuse, rarely acute.
