Celtis adolfi-friderici is a tree in the hemp family. It occurs in central and western Africa and in southern Sudan .
description
Celtis adolfi-friderici grows as a semi- evergreen tree up to 35 (50) meters or more high. The trunk diameter reaches about 1 meter or more. Larger, broad buttress roots are formed. The bark is relatively smooth and grayish.
The simple, short-stalked and leathery leaves are alternate. The short runny leaf stalk is up to 2 inches long. The leaves are entire, almost glabrous and obovate to elliptical, at the tip they are acuminate to acuminate. The leaves are 8-16 inches long and 5.5-9 inches wide. The small stipules are sloping. The veins are threefold and the leaves, with their often uneven blade, are somewhat rough on the underside.
Celtis adolfi-friderici is polygamous-monoecious , the plants are (functionally) monoecious with hermaphrodite flowers. Axillary and multi-flowered, small, short hairy panicles are formed. The mostly five-fold, very small and sessile flowers with a simple flower cover are white-greenish. The flowers are hermaphroditic or functionally unisexual. The hairy, almost free tepals are only 1–1.5 millimeters long. There are free stamens and a top constant, hairy ovary with a short pencil with two two-column, larger scars branches present. The male flowers have a pistillode, the female staminodes. The female and hermaphrodite flowers are at the top of the upper inflorescences. The male flowers are tightly packed together.
The round to egg-shaped, bare, yellowish-reddish when ripe, single-seeded stone fruits with stylus and scar remnants at the tip are up to 2 centimeters in size. The round to ellipsoidal stone core is brownish and textured.
use
The seeds should be edible. The leaves and bark are used medicinally.
The medium-weight, light-colored wood is not durable but easy to treat. It is known as Diania or African celtis .
