Cyanastrum is a genus of plants in the family Tecophilaeaceae, native to tropical Africa. It contains three currently recognized species. [2]
Cyanastrum has a corm that lacks a protective tunic. The leaf and the inflorescence emerge from different corm-scales, and are present at different times. The leaf has a short stalk, is basal and is usually single. The inflorescence is a raceme, often with no bracts, the tepals are blue and the flowers have parts in sixes. [3]
The following species are recognized: [2]
Xanthosoma is a genus of flowering plants in the arum family, Araceae. The genus is native to tropical America but widely cultivated and naturalized in other tropical regions. Several are grown for their starchy corms, an important food staple of tropical regions, known variously as malanga, otoy, otoe, cocoyam, tannia, tannier, yautía, macabo, ocumo, macal, taioba, dasheen, quequisque, ʻape and as Singapore taro. Many other species, including especially Xanthosoma roseum, are used as ornamental plants; in popular horticultural literature these species may be known as ‘ape due to resemblance to the true Polynesian 'ape, Alocasia macrorrhizos, or as elephant ear from visual resemblance of the leaf to an elephant's ear. Sometimes the latter name is also applied to members in the closely related genera Caladium, Colocasia (taro), and Alocasia.
Crocosmia (;), montbretia, is a small genus of flowering plants in the iris family, Iridaceae. It is native to the grasslands of southern and eastern Africa, ranging from South Africa to Sudan. One species is endemic to Madagascar.
Cyttaranthus is a plant genus of the family Euphorbiaceae first described as a genus in 1955. It contains only one known species, Cyttaranthus congolensis, native to tropical Africa.
Arisaema triphyllum is a herbaceous perennial plant growing from a corm. It is a highly variable species typically growing 30–65 centimetres (12–26 in) in height with three-parted leaves and flowers contained in a spadix that is covered by a hood. It is native to eastern North America, occurring in moist woodlands and thickets from Nova Scotia west to Minnesota, and south to southern Florida and Texas.
Ancistrocladus is a genus of woody lianas in the monotypic family Ancistrocladaceae. The branches climb by twining other stems or by scrambling with hooked tips. They are found in the tropics of the Old World.
Dichelostemma capitatum, known by the common names blue dicks, purplehead and brodiaea, is a species of flowering plant in the family Asparagaceae, native to the Western United States and northwest Mexico.
Aneilema is a genus of monocotyledonous plants of approximately 60 species. The vast majority of the species are native to sub-Saharan Africa, but a few are found in Oceania and one, Aneilema brasiliense, is from South America. It is the third largest genus in the family Commelinaceae after Commelina and Tradescantia, and it is one of only six genera in the family to occur in both the Eastern Hemisphere and the Western Hemisphere.
Angraecopsis is a genus of plants in the family Orchidaceae. It was first described by Fritz Kraenzlin in 1900 and given its name on account with the genus' similarity to Angraecum species. Angraecopsis are native to Africa, Madagascar, Réunion, Mauritius and the Comoros. The growth habit is rather small and the leaves emerge from a woody stem.
Eremospatha is a genus of climbing flowering plants in the palm family found in tropical Africa. These rattans are uncommon in cultivation and poorly understood by taxonomists;. Closely related to Laccosperma, they differentiated by the near complete absence of bracts and bracteoles. The name is from Greek meaning "without a spathe".
Hyparrhenia is a genus of grasses. Many species are known commonly as thatching grass.
Aerangis luteoalba is a species of epiphytic orchid native to eastern and central Africa. This species includes 2 currently recognized varieties:
Ancistrorhynchus is a genus of flowering plants from the orchid family Orchidaceae. It contains 16 species native to tropical Africa.
Polyspatha is a genus of perennial monocotyledonous flowering plants in the dayflower family. It is restricted to tropical Africa consists of three recognized species.
Cuviera is a genus of flowering plants in the family Rubiaceae native to tropical Africa. It was originally described by Augustin Pyramus de Candolle in 1807 and is named after the French naturalist Georges Cuvier.
Amphiasma is a genus of 7 species of flowering plants in the family Rubiaceae. It was described by Cornelis Bremekamp in 1952. The genus is found from southern Tanzania to Namibia.
Aulacocalyx is a genus of flowering plants in the family Rubiaceae. It is found in tropical Africa.
Craterispermum is a genus of flowering plants in the family Rubiaceae. It contains 16 species that occur in tropical Africa and Seychelles. It is the only genus in the tribe Craterispermeae, of which the divergence time is estimated at 34.8 million years ago.
Maesopsis eminii, the umbrella tree, is a species of tree in the family Rhamnaceae found in India and Africa. It is the only species in the genus Maesopsis. It is often grown as a plantation tree, and as a shade tree in coffee plantations and other crops. Birds and monkeys may disperse the seeds. Since this tree grows fast it is often used for regeneration of destroyed forest lands. Its timber is used for construction and firewood and its leaves for animal fodder.
Kabuyea is a plant genus in the family Tecophilaeaceae, first described as a genus in 1998. It has one known species, Kabuyea hostifolia, native to Tanzania and Mozambique.
Tacazzea is a genus of plants in the family Apocynaceae, first described in 1890. It is native to Africa.
