Description:
Description - Trees to 25 m tall, with a dense, globose to obovate crown; leaf bearing branches 5-10 mm in diameter; sylleptic branches often present. Bark nearly smooth, light gray. Leaf blades elliptic or oblanceolate, glabrous, coriaceous, 15-61 X 6-19 cm, with 10-25 pairs of lateral veins; apices acuminate to long acuminate; bases acute, obtuse, or rounded; margins entire to serrulate. Petioles 10-70 x 2-4 mm thick. Inflorescences suprafoliar, sometimes at the end of sylleptic branches, racemose, tan-to-rusty-tomentose, with 3-6 flowers, the rachis 30-95 mm; pedicels (20-)50-70 mm, with a single caducous basal bract and 2 bracteoles inserted near the middle. Flowers to 18 cm in diameter; calyx of 4 rounded or broadly triangular lobes, 3-5 x 5-11 mm wide, tan- to rusty-tomentose; petals 8, oblong to obovate, 50-70 x 25-50 mm, densely tomentose-papillose in bud, glabrous to puberulous at maturity, white; connate androecial base 15 mm high; outermost filaments 20-22 mm; anthers 3-5 mm, yellow; ovary without costae, tan- to rusty-tomentose, the indumentum of simple, multicellular pointed hairs, (4-)5-locular, glabrous at summit; style conical, 45 mm; stigma with 4-5 lobes. Fruits in clusters at the branch ends, globose, truncate at apex, 55 x 55 mm, with a small umbo; pericarp 10-15 mm thick. Seeds round in cross section, 40 x 40 mm, 1 or 2 per fruit, with a non-expanded funicle 4 mm long.
