Stems: Stems branched repeatedly, spreading, light gray or light brown, glabrous or rarely pubescent, with numerous helically arranged leaf scars near apex, pith solid, latex white, viscous.

Roots:

Leaves: Leaves simple. Alternate. Blades broadly elliptic, 5–7.5 cm long, 2.7–4.5 cm wide. Apex acute, acuminate, or cuspidate. Base cuneate or obtuse. Lower surfaces sparsely pubescent. Margins callose crenulate, rarely callose–serrulate. Petioles 0.5–1.2 cm long. Stipules absent.

Flowers: Flowers in peduncle 0.4–1 cm long; pedicels 1.2–2.8 cm long. Flowers bisexual (perfect), epigynous, zygomorphic, resupinate, protandrous. Perianth 4–5.5 cm long, white tinged green; tube 3.2–3.8 cm long, 0.7–1 cm in diameter; lobes 1.5–2 cm long, 3–4 mm wide. Stamens 5, syngenesious, alternate with the corolla lobes, staminal column slightly exserted, curved or arcuate; anthers connate, dithecal, opening introrsely by longitudinal slits, purple, the 3 dorsal ones a little longer than the 2 ventral ones, the latter with tufts of stiff white trichomes at apex, otherwise glabrous, or sometimes pubescent along the sutures, rarely so on the surfaces, the tube 1–1.3 cm long, 2.5–3 mm in diameter, glabrous; filaments connate above, free from the corolla, 4.5–5.5 cm long, purple or magenta, glabrous.
