description

Tieghemella heckelii grows as a very large tree to over 55 meters high. The trunk diameter reaches over 2.5 meters. There are buttresses , corrugations or sometimes several meters high buttresses formed. The gray-brown bark is cracked to slightly furrowed or scaly when old. The tree has a sticky milky sap .

The simple, stalked and thin-leather, bare leaves are arranged in a screw-like manner at the branch ends. The petiole is 1.5–4 inches long. The elliptical to obovate, whole-margined and rounded-pointed, acuminate to acuminate, less often indented leaves are 6-15 centimeters long. The stipules are missing.

The flowers appear in small clusters (2–4) or individually axillary. The hermaphrodite, stalked and very small, whitish to cream-colored, slightly fragrant flowers are double- coated . The 1 centimeter long calyx is cup-shaped with 8 more or less finely haired tips in two unequal circles. The overgrown crown has a short, 2-3 millimeter long, wide corolla tube with 8 protruding, somewhat longer and three-part lobes. The middle segment of the lobes is much smaller to greatly reduced. There are 8 free, short stamens and alternating 8 short, fleshy staminodes in the corolla tube . The Upper constant, achtkammerige ovary is soft hairy with short, hairy pen .

It forms 8-12 centimeters large, smooth and yellow to orange-yellow, egg-shaped to rounded berries . They contain up to 3 seeds in a yellowish, sticky, soft and juicy pulp with an unpleasant odor. The large, smooth and shiny, brown, ellipsoidal seeds are 5.5–7.5 centimeters in size with a thick seed coat and on one side, almost on one side, a large, rough and slightly textured stigma ( hilum ).

The number of chromosomes is 2n = 24.

Taxonomy

The first description of Basionyms took place in 1907 as Dumoria heckeli (i) by Auguste Chevalier in Compt. Rend. Hebd. Séances Acad. Sci. 145: 267. The division into the genus Tieghemella took place in 1915 (publ. Posthumously) by Marcel Marie Maurice Dubard after Jean Baptiste Louis Pierre in Ann. Mus. Colon. Marseille, sér. 3, 3: 33. Other synonyms are Baillonella heckelii (A.Chev.) Baehni , Mimusops heckelii (A.Chev.) Hutch. & Dalziel .

use

An edible fat , Dumori or Makoré butter , is obtained from the seeds .

The medium to heavy, very durable wood is known as Makoré .
