Flora of North America species comparison

few to several, erect or ascending, sometimes decumbent at base, unbranched or branched, hairs spreading to retrorse, short, scabrid below inflorescence, sometimes becoming medium length to long, soft to stiff, mixed with short stipitate-glandular ones in inflorescence.

several, erect, decumbent at base, unbranched proximally, branched distally, glabrous proximally, hairy distally, hairs sparse, short, stiff.

green, sometimes purplish, linear to lanceolate or narrowly oblong, 1–8.5 cm, not fleshy, margins plane, flat or involute lengthwise, 0(–5)-lobed, apex acute;
