several, straggling to erect, freely branched, 2–7 cm, pilose and glandular, sparsely so proximally.

erect, simple proximal to inflorescence, 25–80 cm, puberulent, glandular distally.

basal leaves withered at time of flowering, distal sessile, proximal petiolate, largest on mid to distal stem;

blade subrotund to broadly ovate-lanceolate, 3–10 cm × 20–70 mm, base cuneate into petiole, apex short-acuminate, sparsely short-pilose.

in 5–7 pairs proximal to inflorescence, sessile, blade lanceolate, narrowed to base, apex acute;

proximal withering, becoming smaller in inflorescence, 2–5 cm × 3–10 mm, sparsely scabrous-pubescent on both surfaces.

cymose, open, few-flowered, leafy, bracteate;

bracts resembling distal leaves.

cymose, terminal, pedunculate, 1–3-flowered, open, bracteate, bracteolate, 10–25 cm, pubescence dense, hairs septate-glandular, septa colorless;

cymes paired at each node;

peduncle ascending, 1–3 cm;

bracts and bracteoles leaflike, reduced distally to 2 mm.

1–3(–4) cm, viscid, with long septate-glandular hairs.

not bent in fruit, 1/2 to equaling calyx.

calyx indistinctly veined, tubular, broadened distally, constricted towards base around carpophore, ± umbilicate, 20–25 × 5–8 mm, herbaceous, glandular-pilose, lobes triangular, 3–4 mm, margins narrow, membranous, ciliate;
