Quassia is a plant genus in the family Simaroubaceae. Its size is disputed; some botanists treat it as consisting of only one species, Quassia amara from tropical South America, while others treat it in a wide circumscription as a pantropical genus containing up to 40 species of trees and shrubs. The genus was named after a former slave from Suriname, Graman Quassi in the eighteenth century. He discovered the medicinal properties of the bark of Quassia amara.
Zygophyllaceae is a family of flowering plants that contains the bean-caper and caltrop. The family includes around 285 species in 22 genera.
Persicaria maculosa is an annual plant in the buckwheat family, Polygonaceae. Common names include lady's thumb, spotted lady's thumb, Jesusplant, and redshank. It is widespread across Eurasia from Iceland south to Portugal and east to Japan. It is also present as an introduced and invasive species in North America, where it was first noted in the Great Lakes region in 1843 and has now spread through most of the continent.
The Simaroubaceae are a small, mostly tropical, family in the order Sapindales. In recent decades, it has been subject to much taxonomic debate, with several small families being split off. A molecular phylogeny of the family was published in 2007, greatly clarifying relationships within the family. Together with chemical characteristics such as the occurrence of petroselinic acid in Picrasma, in contrast to other members of the family such as Ailanthus, this indicates the existence of a subgroup in the family with Picrasma, Holacantha, and Castela.
Cussonia is a genus of plants of the family Araliaceae, which is native to the Afrotropics. It originated in Africa and has its center of distribution in South Africa and the Mascarene Islands. Due to their striking habit, they are a conspicuous and easily recognizable group of plants. Their genus name commemorates the botanist Pierre Cusson. The Afro-Malagasy and Asian Schefflera, and Afrotropical Seemannaralia genera are related taxa that share several of its morphological characteristics, among which the leaves borne on the end of branches, inflorescences carried on terminal branches or stems, and reduced leaf complexity in developing inflorescences.
Xylopia elliotii is a species of plant in the Annonaceae family. It is found in Ghana and possibly Ivory Coast.
Margaritaria discoidea is a tree in the family Phyllanthaceae, commonly known as the pheasant-berry, egossa red pear or bushveld peacock-berry. These trees are native to the warmer, higher rainfall areas of Africa.
Acer heldreichii is a species of maple in the flowering plant family Sapindaceae. Commonly called Balkan maple, Greek maple, Heldreich's maple, or mountain maple the species is native to the Balkan Peninsula east along the southern and eastern coasts of the Black Sea.
Hypodaphnis is a monotypic genus of flowering plants of the family Lauraceae. Its only extant species, Hypodaphnis zenkeri, is native to Gabon. Although only one living species is known, fossils of some species of this genus are present in North America, especially in Northern Mexico. In most phylogenetic analysis, Hypodaphnis appears as the basal branch, the sister group of the rest of the family Lauraceae.
Cola is a genus of trees native to the tropical forests of Africa, classified in the family Malvaceae, subfamily Sterculioideae. Species in this genus are sometimes referred to as kola tree or kola nut for the caffeine-containing fruit produced by the trees that is often used as a flavoring ingredient in beverages. The genus was thought to be closely related to the South American genus Theobroma, or cocoa, but the latter is now placed in a different subfamily. They are evergreen trees, growing up to 20 m tall, with glossy ovoid leaves up to 30 cm long and star-shaped fruit.
Beilschmiedia gaboonensis is an evergreen tree in the subgenus Hufelandia of the genus Beilschmiedia, in the family Lauraceae. It is native to central Africa. It is a medium-sized tree which can measure up to 30 m tall with a bole diameter of up to 60 cm. It is distributed from southern Nigeria to the Congo basin, occurring in Cameroon, Gabon and Zaïre. It is associated with marshy locations in lowland rainforest. Similarly to Beilschmiedia mannii, it is known under the trade names "kanda" and "pink kanda". The bark is used in analgesic and healing ointments.
Madhuca crassipes is a plant in the family Sapotaceae. The specific epithet crassipes means "thick foot or stalk", referring to the fruit stalk.
Madhuca korthalsii is a tree in the family Sapotaceae. It is named for the Dutch botanist P. W. Korthals.
Palaquium multiflorum is a tree in the family Sapotaceae. The specific epithet multiflorum means "many flowers".
Ficus altissima, commonly known as the council tree and lofty fig, is a species of flowering plant, a fig tree in the family Moraceae. It is a large, stately evergreen hemiepiphyte and is native to southeastern Asia.
Klainedoxa is a group of African trees in the family Irvingiaceae, described as a genus in 1896. It is native to Africa.
Raphia farinifera is a tropical African palm tree occurring in lowland riparian and swamp forest, also around human habitations and cultivated locations, on stream banks and other moist situations at altitudes of 50–1000 m. Found in Angola, Benin, Burkina, Cameroon, Gambia, Ghana, Guinea, Ivory Coast, Kenya, Madagascar, Malawi, Mauritius, Mozambique, Nigeria, Réunion, Senegal, Seychelles, Sierra Leone, Tanzania, Togo, Uganda, Zambia and Zimbabwe, and naturalised in Madagascar. Its generic epithet is derived from raphis = 'needle', probably in reference to the 4 mm long yellowish spines on the margins and main veins of the leaflets. The specific name refers to a type of starchy flour obtained from the trunk pith – farina = 'starch', fera = 'bearing'.
Meiocarpidium lepidotum is a species of plant in the family Annonaceae. It is native to Cameroon, The Central African Republic, The Republic of the Congo, and Gabon. Daniel Oliver, the English botanist who first formally described the species using the basionym Unona lepidota, named it after rust-colored, shiny scales on its branchlets, the underside of its leaves and its buds.
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.
Sacoglottis gabonensis, commonly known as bitterbark tree or cherry mahogany is a medium to large sized evergreen tree within the Humiriaceae family. It is the only species within the genus, Sacoglottis that is native to tropical Africa, another, guianensis Benth. being native to Amazonia. It occurs in rainforests or on sandy soils of Senegal eastwards to Angola in central Africa. It is trade locally and known in some countries under the name, Ozouga.
