The Strelitziaceae are a family of monocotyledonous flowering plants, very similar in appearance and growth habit to members of the related families Heliconiaceae and Musaceae (banana family). The three genera with seven species of Strelitziaceae have been included in Musaceae in some classifications, but are generally recognized as a separate family in more recent treatments such as the APG II system (2003). The APG II system assigns the Strelitziaceae to the order Zingiberales in the commelinid clade.

Circaeasteraceae is a family of two species of herbaceous plants native to China and the Himalayas. The family has been recognized by many taxonomists. The APG II system (2003; unchanged from the APG system of 1998), recognizes it and places it in the order Ranunculales in the clade eudicots. It treats the family to consist of two genera each with a single species, Circaeaster agrestis and Kingdonia uniflora, but allows the option of segregating the latter species as family Kingdoniaceae. The APG III system of 2009 also recognizes the two species but no longer allows the optional segregation

Petrosaviaceae is a family of flowering plants belonging to a monotypic order, Petrosaviales. Petrosaviales are monocots, and are grouped within the lilioid monocots. Petrosaviales is a very small order composed of one family, two genera and four species accepted in 2016. Some species are photosynthetic (Japonolirion) and others are rare, leafless, chlorophyllous, mycoheterotrophic plants (Petrosavia). The family is found in low-light montane rainforests in Japan, China, Southeast Asia and Borneo. They are characterised by having bracteate racemes, pedicellate flowers, six persistent tepals,

Tetrameristaceae is a family of flowering plants. The family consists of three species, of trees or shrubs, in three genera: Pelliciera in Central and South America Pentamerista in the Guyanas Tetramerista in Southeast Asia The APG II system places this family in the order Ericales, of the asterids. In the APG III system, the genus Pelliciera, previously treated as its own family, Pellicieraceae, is included in Tetrameristaceae.

Dirachma is the sole genus of the family Dirachmaceae. The genus had been monotypic, its sole species being the woody plant Dirachma socotrana, until a second, herbaceous, species, Dirachma somalensis, was discovered in Somalia and described in 1991.

Erythrina lysistemon is a species of deciduous tree in the pea family, Fabaceae. It is native to South Africa.

It is regularly cultivated as a tree for gardens and parks.

Pentadiplandra brazzeana, also known as oubli, is an evergreen shrub or liana that is the only species assigned to the genus Pentadiplandra, and has been placed in a family of its own called Pentadiplandraceae. It produces large red berries, sometimes mottled with grey. It is known from West-Central Tropical Africa, between northern Angola, eastern Nigeria and western Democratic Republic of Congo. The berry is sweet in taste due to the protein, brazzein, which is substantially sweeter than saccharose. Brazzein may be useful as a low-calorie sweetener, but is not yet allowed as a food additive

The tribe Desmodieae is one of the subdivisions of the plant family Fabaceae. It is composed of two subtribes, Desmodiinae and Lespedezinae. Recent phylogenetics has this tribe nested within tribe Phaseoleae.

Paraquilegia is a genus of flowering plants belonging to the family Ranunculaceae. The genus was segregated out from the genus Isopyrum in 1920 by British botanists James Ramsay Drummond and John Hutchinson. The native range of the genus is temperate central Asia. Despite the genus encompassing a relatively small number of taxa, there has been significant disagreement among taxonomic authorities regarding how many Paraquilegia species there are and what they are named. In cultivation, Paraquilegia are grown by rock gardeners. The plants are notably difficult to grow. While significant

Daniellia oliveri is a species of tree in the family Fabaceae. It is native to tropical West and Central Africa and is commonly known as the African copaiba balsam tree, or the West African copal tree.

Brachystegia tamarindoides, known as mu'unze and also as the mountain acacia, is a medium-sized tree with smooth grey bark, bluish-green leaves and small creamy-white flowers that produce copious amounts of pollen and nectar. It is almost always very close to upturned umbrella shaped with a partially developed flat top, making it easy to recognise in mixed woodland. In this it differs from most of the other Brachystegia species that have variable shapes. The leaves are feathery in appearance, with around 10-12 leaflets arrayed along each leaf stalk.

Neoalsomitra is a genus of flowering plants belonging to the squash family. Its native range is Tropical and Subtropical Asia to Fiji.

Gardenia erubescens is a species of shrub or small tree in the family Rubiaceae. It has edible fruits and occurs in the Guinea and Sudan savannah vegetation of West and Central Africa.

Boswellia dalzielii is a tree species in the family Burseraceae found in Africa. The bark of this plant is used in traditional medicines. Gallic and protocatechuic acids were isolated as the main antibacterial and antioxidant principles of the stem bark of B. dalzielii. 4'-Methoxy-(E)-resveratrol 3-O-rutinoside, incensole and b-sitosterol were also isolated.

Anubias gigantea is an aquatic to riparian aroid species belonging to the genus Anubias, within the Araceae (the arum family). It was first mentioned by Auguste Chevalier in 1920, based on material that he had collected in Guinea, West Africa. The formal description followed in 1939 by John Hutchinson. It is closely related to A. afzelii, basically only differing from that species by the form of the leaf-blade, with mature growth appearing somewhat different than the juvenile plants.

Xylopia discreta is a species of plant in the Annonaceae family. It is native to Brazil, Colombia, French Guiana, Guyana, Suriname, and Venezuela. Carl Linnaeus the Younger, the botanist who first formally described the species using the basionym Unona discreta, named it after its purple, aromatic fruit which set it apart (discretus in Latin) from other members of the family.

Talbotiella gentii is a medium-sized forest tree in the family Fabaceae. It is endemic to Ghana. It is threatened by habitat loss and is a species monitored by Ghana as a measure of environmental success in preserve biodiversity in forests.

Pavetta mollissima is a species of plant in the family Rubiaceae. It is found in Ghana and possibly Ivory Coast. It is threatened by habitat loss.

Paraquilegia microphylla is a species of perennial flowering plant in the family Ranunculaceae. It is native across a range spanning Siberia, Central Asia into the Himalayas, and east to Japan. The species has flowers that vary in color across its range, with P. microphylla in the western Himalayas possessing small white flowers while those in the eastern Himalayas produce larger lilac flowers. P. microphylla is the most common member of the genus Paraquilegia in cultivation, though it is often misidentified as Paraquilegia anemonoides. P. microphylla seeds have been introduced to gardeners
