Strophanthus is a genus of flowering plants in the family Apocynaceae, first described as a genus in 1802. It is native primarily to tropical Africa, extending to South Africa, with a few species in Asia from southern India to New Guinea and southern China. The genus name is a compound of the Greek words στροφος (strophos) "twisted" and ανθοσ (anthos) "flower", in reference to the corolla lobes which, in some species - notably S. petersianus - resemble long twisted ribbons or threads and can reach a length of 30–35 cm. This trait, in addition to colouring involving combinations of bright pinks, purples and oranges, combine to make the flowers among the most ornamental in the plant kingdom.

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.

Palisota is a genus of plant in family Commelinaceae, first described in 1828. It is native to sub-Saharan Africa.
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 are differentiated by the near complete absence of bracts and bracteoles. The name is from Greek meaning "without a spathe".
Stylochaeton is a genus of flowering plants in the family Araceae that is native to Africa. Stylochaeton are rhizomatous with hastate leaves. Flowering in this genus is said to be quite uncommon. Stylochaeton is the sole genus in the tribe Stylochaetoneae.
Cercestis is a genus of flowering plants in the family Araceae. The species in this genus are all climbers and are native to Africa. At intervals along the stem they produce long leafless shoots called flagella. Many of the species in Cersestis show signs of fenestration.
Culcasia is a genus of flowering plants in the family Araceae, native to tropical Africa. Most of its species are climbers and resemble Cercestis, except that they do not produce flagella.

It can be found in west tropical Africa, west-central tropical Africa, northeast tropical Africa (Ethiopia), east tropical Africa, and south tropical Africa.
