erect, with 3–6 pairs of leaves below inflorescence, 30–80 cm, short-pubescent, glandular and somewhat viscid distally.

sessile at mid and distal stem, petiolate to spatulate proximally;

petiole equaling or longer than blade of basal leaves;

blade ovate to elliptic, 3–13 cm × 10–50 mm (not including petiole), apex acute to acuminate, sparingly pubescent, densely so on abaxial midrib.

proximal petiolate, blade oblanceolate, 3–6(–8) cm × 5–15 mm (including petiole), base tapered into short petiole, apex acute to obtuse and apiculate, short-pubescent on both surfaces, pubescence rather sparse adaxially;

cauline leaves sessile, blade elliptic-lanceolate, 2–6 cm × 5–15 mm.

dichasial cymes, several- to many-flowered, open, bracteate;

bracts lanceolate, 4–20 × 2–7 mm, herbaceous, softly hairy throughout with long-septate hairs, not glandular, or with some glandular hairs.

branched, several–many-flowered, open, bracteate, flowering portion to 15 cm and ca. 1/2 as broad, glandular and viscid;

cymules usually 1–3-flowered;

nodding;

calyx prominently 10-veined, tubular to campanulate, umbilicate but narrowed at base, lobed, 9–11 × 3–5 mm in flower, in fruit ovate to turbinate, 5–8 mm broad, viscid-pubescent, veins parallel, green, papery between;

lobes 5, narrowly lanceolate, obtuse, 2–3 mm, ciliate;

corolla ± white, often greenish abaxially and pink tinged, 2 times calyx;
