Agonandra brasiliensis is a tree in the Opiliaceae family. It occurs from Panama to Guiana and Paraguay.
description
Agonandra brasiliensis grows as an evergreen tree up to 8–15 meters high. The trunk diameter reaches up to 25 centimeters. The brown, coarse and furrowed to cube-cracked bark is thick and corky .
The simple, alternate and bare, thin, slightly leathery leaves have short stems. The petiole is up to 2–4 inches long. The entire, ovate to elliptical, ovate or less often obovate and acuminate, pointed to acuminate or tailed leaves are 4.5–9 centimeters long and 3–5.5 centimeters wide. The stipules are missing.
Agonandra brasiliensis is dioecious diocesan . Terminal or axillary, short and multi-flowered, slender grapes are formed, the male ones are longer and multi-flowered. The unisexual, greenish and short-stalked, very small flowers are 4–5-fold with a double (or, according to another view, simple) inflorescence . They stand individually or up to four on a sloping bract and are sometimes two tiny pre- leaves. The male flowers have a small, cup-shaped and slightly 4–5-lobed, finely haired calyx ("calyculus" or flower cup , torus) and 4–5 externally glandular and fine-haired, egg-shaped petals (or tepals ) up to 3 millimeters long and 4– 5 short stamens and a small, conical, bare pestle and a disc with scaly, upright lobes. The female flowers have very early falling, very small, fine-haired petals (or tepals) and it is a small, cup-shaped, slightly 4-5-lobed, fine-haired calyx ("calyculus" or flower cup, torus) and an upper, single-chambered, bald ovary with Seated, disc-shaped, slightly lobed, fleshy scar and a low cup-shaped disc are present.
Green, round to egg-shaped and smooth, about 2.5-3.5 centimeters large drupes are formed. The large beige stone core is relatively smooth and egg-shaped. The sticky pulp is juicy.
use
The fruits are mostly used cooked. A semi-drying oil can be obtained from the seeds. A foamy, beer-like drink can be made from the roots.
The leaves, roots and bark are used medicinally.
The bark provides a cork. The bark extract is molluscicidal .
The moderately resistant, light, satin wood- like wood is used for some applications.
