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

few to many, erect or ascending, unbranched or branched, glabrate proximally or hairy, hairs usually spreading to weakly appressed, whitish or yellowish, short to long, stiff to ± soft, eglandular to rarely stipitate-glandular.

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 to red-brown or deep purple, linear-lanceolate to lanceolate or linear, (1.5–)5–10.5 cm, not fleshy, margins plane, sometimes ± wavy, flat to involute, 0-lobed, sometimes 3–5-lobed distally immediately below inflorescence, apex acuminate, caudate, or acute, sometimes obtuse;

lobes ascending-spreading, linear to narrowly lanceolate, sometimes with earlike appendages, short, apex acute to 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.

2–16 × 1–2.5 cm;

bracts yellow, yellow-green, or pale whitish throughout, sometimes with dull reddish-purplish wash proximally, especially with age, proximal few lanceolate, most broadly lanceolate to ovate or lanceolate to oblong, 0–5(–7)-lobed, sometimes central lobe with a few small teeth;

lobes ascending to erect, linear, sometimes expanded distally, short, arising near or above mid length, central lobe apex obtuse to rounded or truncate, lateral ones acute to obtuse.
