Duguetia staudtii is a medium-sized evergreen tree within the Annonaceae family. Species is one of four within the genus Duguetia that is native to Africa. [2]
Tree grows up to 36 meters tall. Straight, cylindrical trunk that can be branchless for up to 20 meters, stem bark is rarely scaly, commonly thick and soft and yellow or grey-green in colour. [3] Leaf: simple, alternate arrangement, petiole, 0.2 - 0.5 cm. Leaf-blade, narrowly elliptical to obovate in outline, 10 x 24 cm long and 2 x 5 cm wide; [4] dark green upper surface is coriaceous and glabrous while lower surface is duller. [3]
Occurs in Tropical West and Central Africa, from Sierra Leone to the Central African Republic and southwards to Gabon and the Democratic Republic of Congo. It is locally called Ntom in Central African Republic. [5]
Stem bark contains the bioactive compounds, 2,4,5 trimethoxystyrene and 1-(2,4,5- trimethoxyphenyl)-ethanone. [6] [7] It contains members of the group of alkaloids: berberines, tetrahydroprotoberberines and aporphines. [8]
Bark extracts used by traditional healers as treatment for bronchitis, toothache, edema and head lice. [6] Wood used as timber in local carpentry work, especially as planks or for poles in house construction. [5]
The Annonaceae are a family of flowering plants consisting of trees, shrubs, or rarely lianas commonly known as the custard apple family or soursop family. With 108 accepted genera and about 2400 known species, it is the largest family in the Magnoliales. Several genera produce edible fruit, most notably Annona, Anonidium, Asimina, Rollinia, and Uvaria. Its type genus is Annona. The family is concentrated in the tropics, with few species found in temperate regions. About 900 species are Neotropical, 450 are Afrotropical, and the remaining are Indomalayan.
Annona squamosa is a small, well-branched tree or shrub from the family Annonaceae that bears edible fruits called sugar apples or sweetsops. It tolerates a tropical lowland climate better than its relatives Annona reticulata and Annona cherimola helping make it the most widely cultivated of these species. Annona squamosa is a small, semi-(or late) deciduous, much-branched shrub or small tree 3 to 8 metres tall similar to soursop. It is a native of tropical climate in the Americas and West Indies, and Spanish traders aboard the Manila galleons docking in the Philippines brought it to Asia.
Distemonanthus is a genus of flowering plants in the family Fabaceae. It belongs to the subfamily Dialioideae. It contains a single species, Distemonanthus benthamianus, a deciduous tree, which occurs widely but sparsely in the forest regions of Tropical West and Central Africa; it is sometimes confused with Pericopsis laxiflora due to similar morphological features.
Hymenocardia acida is a plant of the family Phyllanthaceae native to tropical Africa. It is a small tree that grows to 10 m tall. Occurs in the Guinea and Sudanian savannah zones and deciduous woodland, from Senegal eastwards to Ethiopia and southwards reaching Zimbabwe.
Myrianthus arboreus, the giant yellow mulberry or monkey fruit, is a dioecious tropical tree in the genus Myrianthus. It lives in the tropical Central African countries of Central African Republic, Gabon, Cameroon, Nigeria, and Tanzania. Its chromosome count is 2n = 28.
Hexalobus crispiflorus is a species of plant in the family Annonaceae. It is native to Angola, Benin, Cameroon, Central African Republic, Congo, DR Congo, Gabon, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Liberia, Nigeria, Senegal, Sierra Leone, Sudan, Togo and Zaire. Achille Richard, the French botanist who first formally described the species, named it after its wavy petals of its flowers.
Xylopia acutiflora (Dunal.) A. Rich is a small tree that grows up to 15 m high, it belongs to the Annonaceae family.
Xylopia staudtii Engl & Diels is a tall tree within the Annonaceae family, it can grow up to 50 meters tall, the tallest height of the African Xylopia trees. It occurs in forest and freshwater swamps in West Africa.
Annickia chlorantha is a tree that grows up to 25 meters tall, it belongs to the Annonaceae family. An important tree used in traditional medical practices for the treatment of malaria and various diseases in Nigeria and Cameroon; oil extracted from stem barks and leaves of the species and Annickia affinis, its more common close kin have been widely studied.
Annickia affinis is small to medium sized tree that grows up to 30m tall, it belongs to the Annonaceae family. Also known as the African yellow wood, it is widely used in Central Africa and parts of West Africa in the treatment of various diseases. Both Annickia affinis and Annickia chlorantha are widely studied and sometimes credited with the name Enantia chrlorantha.
Alstonia congensis, is a tree within the Apocynaceae family and one of two African species within the Alstonia genus, the other being the Alstonia boonei De Wild. Both have similar morphological characteristics.
Osodendron altissimum, formerly known as Albizia altissima, is a low branching tree within the Fabaceae family, it grows along river banks in the Lower and Upper Guinean and Congolian forests of west and central Africa.
Bridelia grandis is an evergreen tree within the Euphorbiaceae family, it occurs in secondary forests of Central and West Africa. Its wood is traded under the name Assas, a name it shares with Bridelia micrantha.
Cynometra ananta is a perennial large tree within the Fabaceae family. Its timber is traded under the name Apome in Ivory Coast and Ananta in Ghana.
Annickia polycarpa is a small to medium-sized tree found in evergreen forests of West and Central Africa, it is within the Annonaceae family. It is also called the African Yellow wood.
Gambeya africana is a medium sized tree within the Sapotaceae family. It is sometimes known as the African Star Apple along with the closely related Gambeya albida. Both species have similar leaf indumentum and are widespread in the Lower and Upper Guinea forest mosaic.
Mammea africana is a medium to large sized tree within the family Calophyllaceae, it is also known as African mammee apple and its timber is traded under the trade name, Oboto. Mammea africana is found in evergreen and semi deciduous forests in West and Central Tropical Africa.
Manilkara obovata is small to large sized evergreen tree within the Sapotaceae family. Its timber is sold under the name Nkunya in Uganda. The species has a wide distribution from Sierra Leone in West Africa moving east to Uganda in Eastern Africa and southwards to Zambia. It is also considered a variable species having different ecotypes.
Entandrophragma angolense, called the tiama, is a tree species with alternate, pinnately compound leaves that are clustered at the ends of branches. It is within the family Meliaceae and has a wide distribution area, occurring in moist semi-deciduous and evergreen forest regions of Tropical Africa from Sierra Leone to Uganda.
Senecio ruwenzoriensis is an African species of plant. While it is widely distributed, it seems to be highly localised in this range.
