Flora of North America species comparison

few to several, decumbent to erect, sometimes leaning, unbranched or often much-branched distally, with a few short, leafy axillary shoots, hairs spreading, short, soft, stipitate-glandular, mixed with long-spreading, eglandular 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.

gray-green, sometimes green, lanceolate-linear to narrowly lanceolate, 1–6.5 cm, not fleshy, margins plane, sometimes wavy, flat to involute, 0(–3)-lobed, apex acuminate;

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

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;
