many, erect, unbranched or branched, sometimes with small, leafy axillary branches, hairs spreading, long, soft, mixed with shorter stipitate-glandular ones.

several to many, erect to ascending, or decumbent, inflorescence erect in high-elevation form, unbranched, sometimes branched, hairs dense, spreading, ashy gray, short and long, soft, mixed with short stipitate-glandular ones.

green or purple-tinged, lanceolate to linear-oblong, 0.8–6.1 cm, not fleshy, margins wavy, involute, 0(–3)-lobed, apex rounded to acute;

lobes spreading-ascending, narrowly lanceolate, apex acute to acuminate.

green, brown, purple, or deep gray, linear or narrowly to broadly lanceolate to sometimes ovate, 0.7–3 cm, not fleshy, margins plane, slightly involute, 0(–3)-lobed, apex acuminate;

lobes ascending to spreading, linear to lanceolate, apex acuminate.

3–34 × 1.5–3.5 cm;

flowers usually distichous, remote, except distalmost;

bracts proximally greenish, distally greenish, reddish, orange-red, or dull orange, rarely yellow, proximal bracts frequently greenish throughout, lanceolate to narrowly ovate or narrowly oblong-elliptic, 0(–3)-lobed, proximal wavy-margined;

1–8.5 × 2–5 cm;

bracts proximally greenish or deep reddish purple, distally burnt orange, sometimes yellow or deep red to deep burgundy, proximal sometimes lanceolate with narrow lobes, distal or all bracts broadly lanceolate to oblong or slightly oblanceolate, (0–)3–5-lobed, appearing dusty with dense, short stipitate-glandular hairs, many with a nodulose to pillarlike, crystallized, usually pigmented exudate, papillose at 40x;
