Caryodendron orinocense grows as an evergreen tree to over 35 meters high, in culture it is only up to about 15 meters high. Buttock roots are often formed in larger specimens . The tree has an orange milky sap .
The alternate, short-stalked, leathery leaves are simple and bare. The petiole is 3–5.5 inches long. The entire, egg-shaped to elliptical or obovate leaves are 22–30.5 inches long and 6.5–10.5 inches wide. They are pointed to pointed at the top. There are glands on top. The stipules fall off early.
Caryodendron orinocense is dioecious dioecious . The inflorescences, with a thick, fleshy rachis, are terminal or almost terminal, long and slender, spike-shaped racemes , the male are often composed of several racemes in panicles. The greenish and unisexual flowers have a simple umbilicus , the petals are missing. The flowers are each underlaid by small bracts . The male, short-stalked flowers sit in small clusters on the rachis and they have 3–4 lobed, somewhat ciliate sepals and 4 free stamens as well as a fleshy, pillow-shaped disc . The female, almost sessile flowers have 5-6 small, dachige sepals and a top constant, spherical, dreikammerigen and bare ovary with minimal stylus and three small scars branches and a discus.
Woody, up to 3.5–6.5 centimeters in size, mostly three-seeded, triple-chambered and loculi and septicidal, thick-skinned capsule fruits are formed. The dark brown seeds with a thin seed coat are roughly egg-shaped.
