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

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.

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, 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.

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;

lobes ascending, triangular, short, arising near apex, apex acute to obtuse.
