blade usually ± elliptic, wide or narrow, margins usually not undulate, apex acute, often narrowly so;

veins and margins ± smooth abaxially.

± evenly distributed along stem, often scattered in young plants or in 1–4 whorls or partial whorls, 3–13 leaves per whorl, horizontal and drooping at tips or ascending, 5–20.5 × 0.6–3.7 cm, 3–17 times longer than wide;
