Flora of North America species comparison

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, often branched distally, sometimes unbranched, sometimes with short axillary shoots, proximal hairs retrorse to appressed, short to moderately long, distal hairs spreading, longer, soft, often 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, linear-lanceolate, rarely broadly lanceolate, (1.2–)2.5–8(–9) cm, not fleshy, margins plane, flat or involute, 0(–3)-lobed, apex acute to rounded;

lobes ascending-spreading, narrowly lanceolate to linear, apex acute or 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.
