Type: Brazil, Pará, south bank of Amazonas, ca. 2 km E of Arumanduba, 52° 27´W, 1°27´S, 27 Jul. 1961,
Liana. Stems with white latex; branchlets terete to subterete when old, very inconspicuously puberulent when young, glabrate at maturity; nodal colleters up to 0.4 mm long. Leaves opposite; petioles 3–9 mm long; blade 4–10.3 × 1.4–4 cm, membranaceous, ovate to ovate-elliptic, glabrous adaxially, inconspicuously puberulent along the midrib abaxially, the apex shortly acuminate, the base obtuse truncate to obtuse, the margin not revolute. Inflorescence shorter than the subtending leaves, axillary, inconspicuously puberulent, few-flowered; peduncle 7–9 mm long; pedicels 6–9 mm long; bracts 1–1.5 × 0.3–0.4 mm, linear to linear-ovate, scarious. Sepals 6–7 × 0.9–1.2 mm, narrowly ovate, acuminate, inconspicuously puberulent; corolla purple, the lobes darker towards center and orange at margins, glabrous or glabrescent externally, the tube 14–15 × 2.7–3.7 mm, not twisted around the stamens; lobes 8–9 × 2.5–3.5 mm, narrowly obovate, totally reflexed during the anthesis; anthers 5.2–5.4 mm long, glabrous dorsally, included; style head 1.9–2.1 mm long; nectary 1–1.2 mm, 5-lobed, ovary as long as the nectary. Follicles 36–38 cm × 0.3–0.6 mm, glabrous, inconspicuously moniliform; seeds 15–17 mm long, glabrous, coma up to 9 mm or absent, tan.
