green or brownish in upland forms, linear-lanceolate to widely lanceolate, linear, elliptic, obovate, or oblong, rarely ovate or cup-shaped, (0.6–)0.8–5 cm, fleshy or not, margins plane, flat, 3–5(–7)-lobed, apex rounded to obtuse or acuminate, abaxial surface often stipitate-glandular, adaxial sometimes shiny, glabrous;

lobes ascending to erect, linear to lanceolate, apex acute or obtuse.

3–20 × 2–3.5 cm;

bracts proximally greenish to dull brown, distally red, orange-red, or scarlet, sometimes orange or yellow, broadly lanceolate or oblong, (0–)3–5-lobed;
