Robust liana. Stem round, glabrous and green. Tendrils glabrous. Stipules linear, falcate, green to green-brown, entire to glandular (0-2 glands), glabrous, 4-12 × 0.5- 2 mm, deciduous. Petiole 7-23 mm long, green to dark green, slightly canaliculated above, glabrous, with two oval sessile glands at the petiole apex (6-18 mm from its base). Leaves simple, 9.2-18.2 x 3.6-8.5 cm, entirely glabrous, green to dark green, lustrous on adaxial surface, cuneate to subcordate base, apex acute, slightly acuminate and mucronate; margin entire to glandular (0-31 marginal nectaries). Peduncles 15-63 mm long, round in section, green, glabrous, stout (diameter 1-3 mm); pedicel 7-19 mm long. Bracts deciduous, pubescent, pink to violet, papery, concave, 27-50 mm long, 10-34 mm wide, with 2-10 sessile, marginal nectaries. Axillary flowers, solitary or in pseudoracemes, pendulous, 13 to 40 mm long (from the nectariferous chamber to the apex of the ovary). Hypanthium pubescent, greenish with more or less anthocyanins outside and white inside, 7-17 mm (including the nectariferous chamber), with a diameter of 10-22 mm at the base of the sepals. Nectar chamber pubescent, greenish, sometimes with anthocyanins on the outside and white inside, 3-9 mm long, with a diameter of 11-18 mm. Sepals pubescent, oblong, 35-70 mm long, 13-22 mm wide, white strongly dotted with red, slightly concave with a subapical awn (0.5-7 mm long). Petals glabrous, oblong, 32-53 mm long and 10-20 mm wide, white to pinkish-white. Corona composed of 3-7 series of filaments, striped white and red to dark purple to violet (purple to violet on the distal half and striped with red to purple on the proximal half); two main series, the outermost 9-29 mm long, the second 31-49 mm long; the other series about 1-2 mm long. Ovary pubescent, yellowish-white, 5.8-12.1 mm long; styles white punctuated with purple, 9-14 mm long, stigmas light yellow. Stamens 7-10 mm long. Androgynophore glabrous, white more or less punctuated with purple, 14-21 mm long with a slightly enlarged base. Operculum membranous, 2-4 mm long, more or less erect, briefly fimbriated.
