Pradosia surinamensis is a tree in the sapote family from northern Brazil , the Guyanas, and Venezuela .
description
Pradosia surinamensis grows as a tree up to 30–32 meters high. The trunk diameter reaches up to 80 centimeters and buttress roots or corrugations are often present. The smooth bark is brown-grayish and scaly with orange spots.
The simple, stalked and almost bare, leathery leaves are alternate, spiral to whorled. The more or less hairy petiole is runny and 0.8-1.5 centimeters long. The leaves are entire and obovate to elliptical, lanceolate and about 5.5-14 centimeters long. At the tip they are slightly rounded, pointed to pointed. The veins are pinnate and slightly embossed on the top and slightly raised on the underside.
The knotty, ramifloral flowers are in small clusters below the leaf nodes at the branch ends. The stalked, green-yellowish and five-fold, very small, hermaphrodite flowers have a double flower envelope . The 5 sepals and the five-lobed crown, with a short corolla tube, are somewhat fine-haired on the outside and bald on the inside. The 5 stamens are located above in the corolla tube. The above constant, multilocular ovary is fine hairy a short bare stylus , the scar is capitate and partly weak lobed.
There are yellow, 2-4 centimeters and seeded, ellipsoid to wrong-ovate, hairless to slightly hairy fine stone fruit with calyx remnants formed. The smooth, somewhat shiny, cartilaginous and blackish, ellipsoidal seeds (stone core) are 1.6-2.5 centimeters long.
