Moabi wood is used for joinery and carpentry in exterior applications, e.g. for doors, windows, garden furniture and marine construction. Its uniform reddish. The moabi (Baillonella toxisperma) has a low population density (about 1 per 10 ha). It only reaches sexual maturity at 90– years, and regeneration occurs. Summary. African Pearwood (Baillonella toxisperma), otherwise known as False Shea Butternut, is a large, tropical tree that can reach up to 60 m high with a.

Its uniform reddish brown colour and fine grain make it popular for veneer, furniture, decorative uses and flooring. The fruit pulp is eaten fresh although tooxisperma contains latex.
The seed kernel contains a baillone,la oil that is used in cooking, for cosmetic purposes and in traditional medicine. The bailloneloa is applied as a pomade to the hair and used in soap manufacture, and it is applied externally to treat rheumatic pains.
The residues of oil extraction are sometimes used as fish poison. Bark decoctions are used to treat kidney problems, toothache, rachitis, vaginal infections and affections of the respiratory and digestive tracts. Toxusperma tree has several ritual uses. Baillonel,a exploitation of moabi started in the mid s. Moabi bark is regularly sold in markets in Cameroon for medicinal purposes; in the amount traded was estimated at baillonellw. The seed oil is sold on local markets, but no statistics are available.
Heartwood pinkish brown to reddish brown, fairly distinctly demarcated from the pinkish white or greyish brown sapwood. The grain is straight to slightly interlocked, texture fine. Wood with satiny lustre on quarter-sawn surfaces. Growth rings more or less distinct.
The timber dries slowly, but with care it seasons without checking and warping. The shrinkage rates are moderate, from green to oven dry 5. Once dry, the wood is stable. The wood is difficult to work due to the presence of silica 0. Stellite-tipped sawteeth are needed. The wood glues, nails and finishes well, and has good steam-bending properties.
Painting and varnishing with the principal industrial products do not cause problems. After steaming for 48—60 hours, rotary peeling and slicing give veneer and plywood of satisfactory quality.
Moabi wood is toxjsperma. It is resistant to fungi, Lyctus beetles and toxispeerma. It is fairly resistant to marine borers. Impregnation by preservatives is difficult or impossible. The allelopathic compound 3-hydroxyuridine has been isolated from toxisperm, stems and roots of moabi; it inhibited the growth of seedlings of some test plants. Moabi wood can be confused with that of other Sapotaceae species having heavy and reddish brown wood, particularly mukulungu Autranella congolensis De Wild.
Roberty and douka Tieghemella africana Pierre. The fatty seed oil is similar to that of Tieghemella and shea butter tree Vitellaria paradoxa C. Very large tree up to 60 —70 m tall; bole up to — cm in diameter, straight and cylindrical, sometimes swollen in lower part, reaching up to 30 m to the first branches, without buttresses; bark 4—5 cm thick, surface red-brown to dark grey, deeply longitudinally furrowed, red-brown in outer part of section, yellow-pink in inner part, little fibrous, toxksperma a sticky latex; crown umbrella-shaped, very large, up to 50 m in diameter, heavy branches spreading and sinuate; ultimate branches very toxisperja, with numerous scars of fallen leaves.
Flowers in dense fascicles at the ends of branches, bisexual, regular; pedicel 2—3 cm long, pubescent; calyx with 2 whorls of 4 lobes c. Fruit a large, globose, smooth berry 5—8 cm in diameter, grey-green, becoming greenish yellow when ripe, containing abillonella —3 seeds in a pale yellowish pulp.
Seeds ellipsoid, slightly laterally compressed, c. Seedling with epigeal germination, hypocotyl short, 0. Baillonella comprises a single species and resembles Tieghemella and Mimusopsthe first differing in the absence of stipules and its thicker seed coat, the latter in its seed with small and basal scar.
Wood-anatomical description IAWA hardwood codes: Germination takes 1—4 weeks. Shade is required for germination, and seeds germinate in abundance under or close to mother trees.
IUCN Red List of Threatened Species
In natural forest, moabi trees of 10 cm in stem diameter have an average annual diameter growth of 1 mm. When the tree bole has attained 1 m in diameter and the crowns have reached or passed the forest canopy, diameter growth is up to 9.
It bailonella been estimated from growth rings and C 14 dating that a tree with a bole diameter of 1 m bailloella years old and one with a diameter of 2. In an year-old plantation in Ekouk Gabon trees grown in full sun showed a mean annual height growth of cm and under partial shade cm.
The tree starts flowering at an age of 50—70 years, when it has reached the light in the upper storey of the forest, but regular fructification starts still later, when the bole has reached 70 cm in diameter.
Fruits are produced annually, but mass production occurs once in 3 years. About seeds per tree are produced within a cycle of 3 years; a single tree produced kg of fruits, including kg of seed kernels.
In Cameroon flowering starts at the end of the long dry season and beginning of the short rainy season, in February to April. It is accompanied by complete defoliation of the tree; when the tree does not flower, it maintains part of its foliage. Fruits ripen just before the start of the long rainy season, from June to August.
The fruiting season lasts up to 4 weeks for an individual tree, but may last 3 months for the whole population. In Gabon moabi fruits become ripe from December to February. Elephants are the main seed dispersers. They eat the fruits, and intact seeds can be found in the droppings.
It is not necessary for the seeds to pass through the intestines for germination, but it does accelerate germination slightly.
Other fruit-eating mammals such as giant pouched rats Cricetomys emini and monkeys may also disperse seeds, as well as man. It usually occurs scattered, with about 1 adult tree per 20 ha, but occasionally loose groups of 5—50 trees are found.
Some forests are rich in moabi trees, e. Dja forest in Cameroon, with on average 0. In Dja forest there is a maximum number of trees in the diameter class 10—40 cm and a secondary maximum at — cm. At the northern limits of the primary Congolean rain forest in Cameroon large moabi trees are abundant, but regeneration is absent. Moabi can be found on all soil types except on marshy soil.
In the nursery the lower half bailonella the seed is buried, with the scar pointing downwards. The mortality of seedlings in the nursery is very low. Partial shading is favourable for seedling development. Under optimal nursery conditions seedlings may toxispegma 35 cm in height after 6 weeks, 45 bailloneloa after 3 months and 1.
The seedling develops a taproot and it is recommended to sow into polythene pots. At the beginning of the short rainy season in Cameroon 4—5-month-old seedlings are planted into the field under the light shade of about 10 retained adult trees per ha. The shade should be removed gradually when a reduction in diameter growth is observed. At present, the only management measure bsillonella natural forest is the maintenance of a minimum diameter limit for exploitation, i.
The Pygmy people highly value large moabi trees for their fruits and conflicts arose in Cameroon between the Pygmies and companies entitled by the government to exploit the forest for timber. This has resulted in a law endowing the village chief with the power to authorize the cutting of a moabi tree within 5 km distance from a village.
The sapwood is susceptible to attack by insects and fungi. In felled toxisperam some of the insects affecting the sapwood e. Platypes and Scolytes spp. Fruits still attached to the tree are attacked by larvae of the beetle Carpophilus sp.
