Plants almost glabrous, up to 25 cm; stem terete, 5-10 cm long, c. 1 cm diameter. Leafblade ovate to broad-ovate, base shallowly emarginate to cordate, apex short or distincdy acute-acuminate, 7-17 by 5-10 cm; petiole 4-6(-15) cm long. Inflorescences shortly peduncled, simple, pauciflor-ous racemes, hidden under the leaves, 2-5 cm long, after flowering bent towards the ground; bracts ovate, 5-12 mm long, leaf-like, one-nerved, the nerve smooth or with ander-like branched emergences, margin translucent and irregularly undulate. Flowers campanulate-urceolate, 12-20 mm long, 18-20 mm diameter; pedicels 3-4 mm long; perianth rather thickly fleshy, connate for slightly over half of its length, pale greenish yellow, tube 6-12 mm long, c. 10 mm wide, lobes roundish, 6-9 mm long, spreading and somewhat recurved in anthesis. Staminal ring fused with the basal part of the perianth tube and the hypanthium; outgrowths of the connectives narrow and somewhat bent down towards the stigma; ovary dentately ribbed, shorter than the perianth, c. 5 mm high, the ribs extending on the perianth-tube; stigma flattish, 3-or 4-lobed.
