#African flora
- Acanthus arboreus — A species of erect shrub or small tree in the Acanthus genus, native to the tropical regions of East and Northeast Africa (such as Ethiopia, Sudan, Kenya, and Uganda). Unlike the predominantly herbaceous species of this genus, this taxon develops vigorous woody stems that can reach heights of 4 to 6 meters. It is characterized by large, deeply lobed, and heavily spiny leaves, and spectacular dense terminal flower spikes with large, bright pink or purple flowers protected by serrated green bracts.
- Adenandra — A genus of perennial, shrubby plants native to the warm regions of South Africa, belonging to the Rutaceae family. These plants are structurally characterized by small, often aromatic leaves due to prominent oil glands, and decorative flowers with five petals shaded in white or pink, being cultivated internationally as ornamental plants due to their resilience in sandy soils.
- Adenandra fragrans — A species of small aromatic shrub native to the Cape region of South Africa, belonging to the Rutaceae family. The plant is structurally recognized for its small glandular leaves that emit an intense, pleasant, and balsamic fragrance when crushed, as well as for its decorative five-petaled white or pink flowers, often utilized in niche ornamental horticulture.
- Agapanthus africanus — The type species of the genus Agapanthus, native exclusively to the Cape region of South Africa, characterized by evergreen, narrow leaves and compact spherical inflorescences with deep blue, sometimes dark purple flowers. Structurally, this plant differs from other horticultural hybrids by its slower growth rate and higher sensitivity to low temperatures, being cultivated worldwide as an ornamental collector's species.
- Agathosma — A genus of small to medium-sized evergreen shrubs in the family Rutaceae, endemic to the Mediterranean-climate regions of South Africa, particularly the Western Cape province. These shrubs are highly recognized for their ericoid, aromatic leaves heavily dotted with oil glands that release a strong, pleasant, or medicinal scent when crushed, holding substantial ecological importance within the fynbos ecosystem alongside unique ornamental and therapeutic values.
- Agathosma imbricata — A specific shrub species within the genus Agathosma, characterized by small, rigid leaves arranged very densely along the stems and partially overlapping one another like roof tiles (imbricate arrangement). This compact foliar structure significantly reduces water loss through transpiration, allowing the plant to survive in exposed rocky habitats within the South African fynbos ecosystem.
- Amphiblemma cymosum — The scientific name of an ornamental tropical herbaceous plant species in the genus Amphiblemma, Melastomataceae family, native to the damp tropical rainforests of West Africa (such as Sierra Leone). It is distinguished by its large, velvety, cordate deep green leaves with conspicuous reddish veins, and by its branched terminal inflorescences (cymes) consisting of bright pink or purple flowers.
- Anacampseros — A genus of small, perennial succulent plants native to the arid regions of Southern Africa, belonging to the family Anacampserotaceae. These structural plants are characterized by fleshy leaves, often covered with silky hairs or membranous stipules that protect them from the scorching sun, and are cultivated by collectors for their unique ornamental appearance and delicate diurnal flowers.
- Anacampseros albissima — A species of dwarf, perennial succulent plant native to the extremely arid regions of South Africa and Namibia, structurally classified under the synonym Avonia albissima. This collector's plant is characterized by thin, cylindrical, and branched stems completely covered by overlapping, white, papery stipules that reflect intense solar radiation and protect the tiny green leaves hidden underneath, producing miniature cream-white flowers.
- Ansellia — A genus of epiphytic or lithophytic orchids, native to the tropical and subtropical regions of Africa, named in honor of the botanist John Ansell. This taxonomic group comprises large plants with robust, cylindrical pseudobulbs and spectacular paniculate inflorescences, representing a unique structural element in African flora due to its adaptations to climates with prolonged dry seasons.
- Ansellia africana — A binomial scientific name for the single widely accepted species in the genus Ansellia (the leopard orchid), a vigorous epiphytic plant widespread in the savannas and open woodlands of sub-Saharan Africa. The species is structurally renowned for its large, greenish-yellow flowers, heavily patterned with brown or chocolate spots, and for its ability to form massive colonies on the branches of large trees, strictly protected under international conventions on threatened flora.
- Antholyza caffra — A historical scientific name and taxonomic synonym for Tritoniopsis caffra (or Chasmanthe caffra), a perennial cormous geophyte native to South Africa. It features narrow linear leaves and lax spikes of 12-20 tubular, bright scarlet-red flowers blooming from spring to summer.
- Antholyza cunonia — A historical scientific name and significant synonym for Gladiolus cunonius, a bulbous perennial plant in the family Iridaceae native to coastal South Africa, famous for its bright scarlet-red flowers with a hood-like upper tepal adapted for sunbird pollination.
- Arctotis breviscapa — The official binary name for a specific plant species within the Arctotis genus, renowned for its relatively short flower stalks (breviscapa) and large, intense orange or golden-yellow blossoms with a dark inner ring at the base of the petals. This structurally compact plant is native to South African Mediterranean-climate zones and is valued as a groundcover in xerophytic landscaping.
- Aristea — A genus of herbaceous, perennial, and rhizomatous plants in the Iridaceae family, primarily native to tropical and southern regions of Africa, as well as Madagascar. The genus comprises around 50 species frequently cultivated as ornamental plants due to their ensiform (sword-shaped) leaves grouped in dense rosettes and spectacular inflorescences with intense blue flowers, a hue rarely encountered in the plant kingdom, which usually open for a single day.
- Aristea corymbosa — Scientific name for a rare and robust shrubby species of perennial plants in the Iridaceae family, native to the mountainous regions of South Africa. This plant is particularly spectacular due to its woody stems, fan-shaped leaves, and dense corymb-like inflorescences that produce intense blue flowers, being cultivated worldwide as a collectible ornamental plant.
- Climbing asystasia — A climbing plant species in the genus Asystasia, family Acanthaceae, native particularly to the forested areas and tropical regions of West Africa. It is distinguished by its long, flexible shoots that lean on surrounding vegetation to reach the light, having glossy leaves and compact terminal inflorescences with tubular flowers, often white or cream, adapted for pollination by large insects in the forest canopy.
- Babiana — Babiana; a genus of herbaceous, perennial, bulbous plants in the family Iridaceae, mostly native to South Africa. These structural plants are cultivated globally for ornamental purposes due to their spectacular funnel-shaped flowers, brightly colored in shades of blue, purple, magenta, or yellow, featuring a delicate lemon-like fragrance.
- Babiana plicata — A species of herbaceous, bulbous plant in the genus Babiana (family Iridaceae), endemic to the Mediterranean climate regions of South Africa; it is structurally distinguished by its strongly longitudinally pleated leaves and fine aromatic hairs, as well as its fragrant funnel-shaped flowers, usually colored in pale shades of blue, mauve, or cream, with distinct markings on the petals.
