Flora of North America species comparison

erect, sparingly branched proximally, slender, 15–35 cm, sparsely glandular-pilose; small axillary tufts of leaves absent.

flowering stems usually erect, 10–25 cm, glabrous to sparsely pubescent proximally, more densely so in mid and distal stem, hairs patent to slightly deflexed, multicellular, glandular and eglandular;

internodes usually equaling or exceeding leaves; nonflowering shoots present; small axillary tufts of leaves absent.

not marcescent;

proximal blades broadly spatulate-petiolate, 8–55 × 3–16 mm, apex acute or obtuse, sometimes short-acuminate, softly pilose;

cauline few, sessile, blade linear-lanceolate to narrowly oblanceolate, 7–30 mm, apex acute, pilose.

sessile (flowering shoots) or petiolate (proximal stems and nonflowering shoots); flowering shoots with blade lanceolate, 5–20 × 2–5 mm, not succulent, apex ± acute, pubescent;

proximal stem and nonflowering shoots with blade oblanceolate often spatulate, not succulent, apex obtuse, ± pubescent on both surfaces (rarely subglabrous), with straight, strigose hairs or cilia, hairs pale, fuscous, mostly eglandular.

very open and loose, 2–9(–25)-flowered cymes;

bracts narrowly lanceolate, pilose.
