cauline in 1–3 pairs, sessile, much reduced, blade linear-lanceolate, not fleshy.

sessile, 2 per node;

blade prominently 3–5-veined, ovate-acuminate, round at base, (4–)6–10(–13) cm × (20–)30–50(–90) mm, appressed-pubescent on both surfaces.

1–5(–7)-flowered, with terminal flower and lateral, open, pedunculate cymes often reduced to single flowers, bracteate;
