erect, branched, rarely simple, 15–45 cm, with long, often crinkled hairs mixed with short pubescence, viscid-glandular distally.

decumbent to erect, simple or branched, leafy throughout, 5–30(–70) cm, usually glandular-puberulent distally, proximal pubescence varying from short and sparse to multicellular, crinkled and deflexed, glandular or not.

2 per node, blade with coarse, ascending, scabrous pubescence on both surfaces;

basal few, withering, blade oblanceolate to spatulate-petiolate, 0.5–5 cm × 3–15 mm;

cauline blades oblanceolate to lanceolate, 1–7 cm × 1–15 mm, apex obtuse or shortly acuminate to acute.

2 per node, sessile or short-petiolate;

blade usually oblanceolate to elliptic-lanceolate, rarely obovate or elliptic, 2–6(–10) cm × 3–20(–35) mm, broadest at or above middle, narrowed to base, margins ciliate with short, somewhat scabrid hairs, apex acute to acuminate, puberulent to pubescent.

open, with racemose branches, internodes and bracts usually ca. equaling fruiting calyx, 1–5 mm, longer proximally.

cymose, or flowers axillary or solitary and terminal;

cyme loose, compound, leafy.

slender, 0.5–3 cm, glandular-puberulent.

5–8 mm diam.;
