Bunchosia glandulifera is a tree in the Malpighia family from northwestern and northern South America .
description
Bunchosia glandulifera grows as an evergreen shrub or smaller tree up to about 7–8 meters high. The bark is grayish-brown, smooth to slightly rough or nodular. The trunk provides a rubber .
Bunchosia argentea is very similar, but here the leaves are not wavy at the edge and are initially on both sides, later only on the underside, thicker and pressed down, silky, hairy, and the leaf glands are different. This often leads to confusion, this species is also not cultivated, in contrast to Bunchosia glandulifera . At some point Bunchosia glandulifera was introduced in the USA as Bunchosia argentea and was further distributed under this name. All photos of these plants on other websites are actually Bunchosia glandulifera . There is also the Bunchosia glandulosa (Cav.) DC. led, this is also very similar and has bald and narrow leaves and two glands at the top of the petiole.
The simple, opposite leaves are short stalked. The somewhat fine-haired petiole is up to 0.5–1 centimeters long. The leaves are ovate to elliptical or obovate, pointed to acuminate at the tip and with a whole and wavy edge. The leaves are up to 10-18 centimeters long and they are above and below, decreasing, hairy with two-branched, white trichomes and they are glandular below. The young leaves are more densely hairy, the leaf hairs then decrease later. There are small stipules present.
Axillary, upright and thick-stemmed, small racemose inflorescences are formed at the branch ends. There are in the flowering small supporting and bracteoles present, and the flower stem is seated at a "hinge" on the short side axis (Peduncle, Floriferis). The hermaphrodite flowers are five-fold with a double flower envelope . The thick-stemmed flowers are yellow. The narrow, short and green, slightly hairy sepals are erect with outside, usually two basal, fused, large, greenish-yellow, elongated and fleshy oil glands. The nailed , yellow petals have a rounded plate that is partly sawn or notched on the edge . The short 10 stamens are fused at the base. The two-chamber, finely hairy ovary is upper constant with a pen with two-piece, fleshy scar .
Egg-shaped to ellipsoidal, almost smooth, slightly hairy and orange to red, briefly tipped berries are formed. There may still be stylus remains at the tip. The small fruits with a thin, somewhat rubbery skin are about 2–3.5 centimeters long and contain 1 or mostly 2 free, about 1–1.5 centimeters long and light brownish, elliptical, somewhat flattened on one side and relatively smooth and bony seeds. The red pulp is sticky, slightly juicy and sweet. You can harvest the fruits not yet fully ripe, still orange, and then leave them to ripen for two days, they will then be red and soft.
