Treatment appears in FNA Volume 10.

Herbs strigillose and glandular puberulent distally. Stems several, unbranched, sometimes with shorter secondary branches, 10–40 (–60) cm. Leaves green, younger ones grayish green, (6–) 8–12 (–14.5) × 0.4–2.3 (–3) cm; blade often lanceolate-elliptic to broadly elliptic, sometimes linear or lanceolate, margins usually flat, sometimes undulate, entire or inconspicuously denticulate, apex acute. Flowers: buds with unequal free tips (4–) 8–10 (–12) mm; floral-tube (78–) 95–115 (–140) mm; sepals (45–) 50–65 (–75) mm; petals (40–) 50–65 (–68) mm; filaments (25–) 30–40 (–44) mm, anthers (15–) 17–24 mm; style (120–) 135–160 (–190) mm. Capsules ovoid, narrowly ovoid, narrowly lanceoloid to broadly ellipsoid, or subglobose, not twisted, wings (14–) 18–34 mm wide, body 52–70 (–115) × 7–8 mm. 2n = 14.
