Description:
Description - Trees, to 30 m tall. Leaf blades widely elliptic to elliptic, 11-18 x 7-9 cm, glabrous, with black punctae abaxially, with 10-12 pairs of lateral veins; apex short acuminate to acuminate; base acute to rounded; margins entire; petiole 7-17 mm long. Inflorescences usually terminal, sometimes in axils of uppermost leaves, once branched paniculate arrangement of racemes, the rachis 525 cm long, all axes sparsely to conspicuously lenticellate, with persistent pedicel bases, the pedicels 5-7 mm long, jointed at middle, lenticellate. Flowers 2-3 cm diam.; calyx with six lobes, the lobes widely ovate, 2-6 x 2-5 mm, ascending to erect, not imbricate to imbricate for ½ length, convex abaxially, flat adaxially; petals six, widely obovate, 14-22 x 10-17 mm, white; hood of androecium 11-13 x 14-19 mm, forming double coil, yellow; staminal ring with 115-200 stamens, the filaments ca. 1-1.5 mm long, clavate, the anthers 0.5 mm long; hypanthium cuneate, puberulous, sparsely to densely lenticellate; ovary 2-locular, each with 4-5 erect ovules attached to placenta at base of septum, the style 2-3.5 mm long. Fruits globose, 2.5-3 x 3-5 cm (excluding operculum), the pericarp 4-5 mm thick; operculum dome-shaped, without umbo, 2.2 cm high. Seeds unknown.

Discussion:
This species is characterized by its snow-white petals which contrast with the light yellow androecial hood.The easternmost collections of this species have smaller, less imbricate Calyx-lobes, and less markedly lenticellate axes of the inflorescence and hypanthium as well as slightly longer pedicels.
