Herbs, perhaps ascending, notably fleshy, to 30 cm tall; stems flattened to terete, drying brown, puberulent to glabrous. Petiole 0.5-3.5 cm; leaf blade drying thickly papery, purplish red or yellowish brown abaxially, broadly ovate or broadly elliptic, 5-12 × 3.5-7 cm, glabrous on both surfaces, abaxially densely minutely orbicular scaly, base obtuse, subrounded, or subcordate, usually oblique, margins entire, apex obtuse to shortly cuspidate; secondary veins 5 or 6 pairs; stipules caducous, not seen. Inflorescences cymose or congested-cymose, many flowered, puberulent; peduncle 2.5-5.5 cm; axes short, helicoid; bracteoles narrowly spatulate, 5-5.5 mm, obtuse. Flowers with biology unknown, with pedicels 2-3 mm. Calyx puberulent; hypanthium turbinate, ca. 2 mm, 10-ribbed; lobes subtriangular, ca. 0.6 mm, in sinus with 1 gland. Corolla purplish red, salverform-funnelform, glabrous outside; tube 24-25 mm, pilose inside; lobes ovate-triangular, ca. 2.2 mm, dorsally ridged with very short horn. Capsules rhomboid, ca. 5 × 15 mm, glabrous or subglabrous. Fl. Oct.
