description
Coelocaryon preussii grows as an evergreen , slow-growing tree up to 35 meters high. The trunk diameter reaches over 80 centimeters. The trunk is often corrugated or there are roots and buttress roots are almost not formed. The red-brown bark is scaly.
The alternate, simple and short-stalked, thin-leather, bare leaves are entire. The short, runny petiole is 1–2 centimeters long. The obovate leaves are 15-25 inches long and 6-8 inches wide, at the tip they are pointed to acuminate. The stipules are missing.
Coelocaryon preussii is dioecious dioecious . Axillary, small and short rusty hairy panicles with small, multi-flowered, doldy groups are formed. The stems of the small, dold-like groups widen in a disc-shaped manner at the tip, and initially the flower groups are covered by a sloping "envelope" (bracts, calyptra). The unisexual, yellow and very small, about 3 millimeters large flowers are short stalked with a simple flower cover . The short and reddish-brown hairy, cup-shaped perianth is 3–4 parts. In the male flowers there are 3 to 5 stamens fused in a synadrium . The uni-, bald ovary of the female flower is upper constant, with a very short pen with two-part scar .
It forms 3.5–4 centimeters, yellowish, round to ellipsoidal and single-seeded fruits that open into two lobes and appear in small groups. The inside hollow, 2–3 centimeters long, dark brown to blackish, smooth and ellipsoidal seeds are almost completely covered by a slashed, reddish to pink aril .
