Description:
Description - Small to medium sized trees, to 30 m. Twigs reddish brown, 2.5-4 mm diam., with round, slightly raised lenticels. Bark with vertical fissures, peeling in rectangular plates. Leaf blades elliptic, 8-34 x 4-11 cm, glabrous, chartaceous, with 11-16 pairs of lateral veins, impressed above; apex acuminate; base obtuse; margins entire to crenulate; petiole 6-20 mm long, glabrous. Inflorescences terminal or in axils of uppermost leaves, racemose, unbranched, the rachis to 15 cm long, with elevated vertically oriented lenticels and horizontally oriented scales; pedicels 2 mm long, with caducous, lanceolate to oblong bract, 4 mm long inserted at base, bracteoles not seen. Flowers ca. 4.5 cm diam.; calyx with six ovate lobes 6-10 x 5-7 mm; petals 11-27 x 14-20 mm, red or purple; hood of androecium flat, dorsiventrally expanded, ca. 21 x 21 mm, red or purple at anthesis, fading white, the appendages almost entirely fused, antherless or with a few vestigial anthers; staminal ring with 200-350 stamens, the filaments 1.5-2 mm long, not clavate, the anthers 0.3-0.5 mm long, hypanthium reddish-brown, cuneate at base; ovary 4-locular, each locule with 6-21 ovules attached on lower part of septum, the summit umbonate, the style not well differentiated from summit. Fruits cylindric to turbinate, 4-7 x 3.5-6 cm, the unaltered calyx lobes persistent, the pericarp 5-10 mm thick. Seeds oblong, 3.5x1 cm, light brown with four white, longitudinally oriented veins, the aril white, basal, 1.5 x 0.5 cm.

Discussion:
This species is morphologically similar to Corythophora amapaensis from which it differs in its deeply versus shallowly fissured bark, unbranched versus branched inflorescence, 4- versus 2-locular ovary, and cylindric to turbinate versus campanulate fruits.
