description
Bysonima crassifolia grows as a mostly evergreen shrub or smaller tree up to about 7-10 meters high. The rough bark is gray-brown and thick and coarse scaly when old. The young twigs are densely hairy with rusty hair.
The simple, opposite and leathery leaves have short stalks. The slightly fine-haired petiole is up to about 0.8-1.3 inches long. The leaves are ovate to lanceolate or lanceolate to obovate, pointed to pointed at the tip, rarely rounded or indented and with a whole, slightly bent edge. The leaves are up to 7-14 centimeters long, 3-7 centimeters wide and they are above and below more or less, decreasing, short rusty hairy, on top less and the central vein remains hairy the longest. The young leaves are more densely covered with rusty hairs, the hairs on the leaves then decrease later. The color of the hairs sometimes changes from brownish to white, greyish. There are small stipules present.
There are terminal, erect, stalked and about 10-18 centimeters long traubig- panicles formed, Multiflora inflorescences. The rachis and the peduncle are more or less hairy with rust and there are sloping bracts under the inflorescences. The hermaphrodite, stalked flowers are five-fold with a double flower envelope . There are in the flowering each small supporting and prophylls present and the flower stem is seated sometimes to a "joint" in the short lateral axes (Peduncle, Floriferis). The flower stalk is rusty hairy short. The narrow, short and green, later yellow, slightly hairy sepals are triangular and upright, with on the outside, usually two overgrown, large, greenish to later yellow, elongated and fleshy oil glands. The long- nailed , initially yellow, later orange-red petals have a round, disc-shaped and partly sawn from the edge until notched plate . The 10 short stamens with elongated, slightly hairy anthers are tightly overgrown and hairy at the base. The draft tube, often finely hairy ovary is upper constant, with three pfriemlichen pencils with very small, capitate scars .
Small, round and yellow to orange, more rarely green, smooth, almost bare stone fruits are formed. The round navel is sunk a little and at the tip there may be remains of a stylus. The fruits are about 1.5–3.5 centimeters tall, thin-skinned and smell of cheese . The whitish, soft, slightly oily, slightly juicy flesh is slightly sweet, slightly sour and floury-fibrous. The hard, light brownish, egg-shaped to elliptical, bony stone cores are carved, pitted and about 6–10 millimeters long, as well as partly pointed. They contain up to three, beige seeds .
use
The fruits, with a taste that takes getting used to, are edible and are used raw or cooked. The bark is used medicinally.
The reddish wood is heavy, hard, tough, somewhat brittle and only moderately durable. The wood is usually only available in small quantities, but it is valued for various uses. The wood has a pleasant scent when burned and is used to make guarana .
