description

Vegetative characteristics

Dacryodes edulis grows as an evergreen tree up to 40 meters tall with a richly branched and dense crown. In culture, however, it usually does not grow taller than 20 meters. The trunk diameter can be over 90 centimeters, the trunk is often slightly fluted at the bottom. The relatively smooth bark is grayish-brown with horizontal folds and breaks off into plates. The tribe carries an aromatic resin (Kongo- Elemi ). The young twigs are hairy brown and tomentose.

The mostly alternate, stalked leaves are mostly unpaired pinnate and up to 40 centimeters long, with more or less hairy rachis . The stalked, shiny and entire-margined leaflets are up to 20 centimeters long and ovate to lanceolate or oblong, less often obovate, as well as pointed to pointed or tail. The lighter underside of the leaflet is more or less hairy, especially on the protruding, thick, brownish central vein. There are sloping pseudo next sheets available (small modified leaves).

Generative characteristics

Dacryodes edulis is dioeciously separated sexually dioecious ( gynodioce , andromonoce ), with female and male-hermaphroditic plants. Up to 40 centimeters long axillary, short brownish hairy panicles are formed, whereby the female inflorescences are significantly smaller. The fragrant and mostly threefold flowers with a double inflorescence are short stalked and underlaid with bracts . The three-part calyx is brownish and tomentose. The slightly larger, yellowish petals are tomentose on the outside. The female flowers staminodes and a top constant, zweikammeriger are ovary with very short pencil and a two to vierlappgen scar and a lobed discus present. The male flowers have six stamens and one pestle, as well as a reduced disc.

Egg-shaped to ellipsoidal, about 4.5 to 12 centimeters long and 2.5 to 6 centimeters wide, violet, purple or pink to bluish, also mixed with reddish or white, to blackish and solitary stone fruits are formed. The exocarp is thin, firm, smooth, and waxy. The reddish-white to yellow-greenish, fibrous and oily-fatty flesh is soft, the elongated and brownish, leathery, smooth stone core, with a relatively thin seed coat , is about 3.7 to 10.7 centimeters long, it contains thick and wrinkled ones , lobed cotyledons . The young fruits are reddish.

The number of chromosomes is 2n = 40 or 42.
