Bot. Gaz. 25: 269. 1898.
Herbs, perennial, (2.3–) 3–8 dm; from a woody caudex; with a taproot. Stems solitary or few-to-many, erect, branched distally, sometimes unbranched or with short, leafy branches in axils of leaves, glabrous, sometimes hairy, hairs moderately dense, spreading, short, soft, eglandular. Leaves green, sometimes purplish, linear or narrowly lanceolate, 1–9 cm, not fleshy, margins plane, involute, 3–5 (–9) -lobed, apex acuminate to narrowly acute; lobes spreading, linear, arising near or below mid length, apex acute, rarely obtuse. Inflorescences 3–15 (–20) × 1.5–3 cm; bracts proximally pale greenish to pale yellowish green, distally white, cream, or pale-yellow, sometimes pale greenish, pale yellow-green, or pale-yellow throughout, lanceolate to narrowly elliptic, 3–5 (–7) -lobed; lobes ascending or spreading, linear to very narrowly linear, long, arising above or below mid length, apex acute to obtuse. Calyces green, rarely pale-purple, lobes white, cream, or pale-yellow, 18–24 (–27) mm; abaxial clefts (6–) 8–16 mm, adaxial 4–10 (–14) mm, abaxial 45–60% of calyx length, adaxial 15–40% of calyx length, deeper than laterals, lateral 1–4 mm, 5–15% of calyx length; lobes narrowly triangular to linear, apex acute. Corollas straight or ± curved, 16–25 mm; tube 15–17 mm; beak exserted from calyx, adaxially green, 5–7 mm; abaxial lip deep green, reduced, exserted through abaxial cleft, 1–4 mm, 40–60% as long as beak; teeth erect, white, 0.5–1 mm. 2n = 24.
