The Asclepiadoideae are a subfamily of plants in the family Apocynaceae. Formerly, they were treated as a separate family under the name Asclepiadaceae, e.g. by APG II, and known as the milkweed family.
Stapeliinae is a subtribe of flowering plants within the tribe Ceropegieae of the subfamily Asclepiadoideae of the family Apocynaceae. The subtribe comprises about 35 genera, including both the stem-succulent "stapeliads" and the horticulturally popular genera Brachystelma and Ceropegia. The largest number of genera are native to Africa, but a more limited number of genera are widespread in Arabia and Asia. Historically, a similarly circumscribed taxon was treated as a separate tribe, Stapelieae.
The genus Huernia consists of perennial, stem succulents from Eastern and Southern Africa and Arabia, first described as a genus in 1810.

Sansevieria is a historically recognized genus of flowering plants, native to Africa, notably Madagascar, and southern Asia, now included in the genus Dracaena on the basis of molecular phylogenetic studies. Common names for the 70 or so species formerly placed in the genus include mother-in-law's tongue, devil's tongue, jinn's tongue, bow string hemp, snake plant and snake tongue. In the APG III classification system, Dracaena is placed in the family Asparagaceae, subfamily Nolinoideae. It has also been placed in the former family Dracaenaceae.

Euphorbia abyssinica, commonly known as the desert candle or candelabra spurge, is a species of plant in the family Euphorbiaceae. E. abyssinica is endemic to Ethiopia, Somalia, Sudan and Eritrea. It was first described in 1791, by the German botanist Johann Friedrich Gmelin. In its native habitat, it can grow up to 10 m (33 ft) tall. The woody stem is used for firewood and as timber in roofing, furniture and other items, and the sap is used in traditional medicine. It is also cultivated as an ornamental house plant.
Aloe haworthioides is a species of plant in the genus Aloe native to Madagascar. This aloe is named for its leaves, which are covered with soft spines that create a resemblance to Haworthia species. A small species, it grows in stemless, clumping offsets and sports orange, highly fragrant flowers.

Flowers by way of a shoot and produces a large off-white flower.
Pseudolithos migiurtinus is a species of succulent plant in the genus Pseudolithos. Native to Somalia, it is akin to other species in the genus in that it grows in arid environments and is a small, leafless plant that looks somewhat like a stone, hence the name. It can range from green to ochre in color. This species is up to 120 millimetres (4.7 in) high and 65 millimetres (2.6 in) around, can be either cubiform or cylindrical in form, and may grow small branching columns in older plants.
Pseudolithos horwoodii is a species of succulent plant in the genus Pseudolithos. Native to arid areas of Somalia, it is a small, leafless plant up to 80 millimetres (3.1 in) tall and 45–60 millimetres (1.8–2.4 in) wide. Its growth habit is squat, unbranched, and blob-like, living up to the name of its genus which means "false stone". Its color is green to grayish brown.
Pseudolithos caput-viperae is a species of succulent plant in the genus Pseudolithos. It is a small, leafless plant up to 15–40 millimetres (0.59–1.57 in) tall and either green or brownish. First discovered and described in the 1970s by botanists John Jacob Lavranos and Renato Bavazzano, it is native to Somalia. The seedlings of the plant are identical to Pseudolithos migiurtinus, but start to branch after a year, making this the only member of Pseudolithos that is not just a single squat stem. Its Latin species name means "snake head".
Cheiridopsis peculiaris is a species of succulent plant in the genus Cheiridopsis native to South Africa. Its name refers to the peculiar leaf shape compared to other species in its genus. Like other Cheiridopsis it has leaf pairs, but unusually the outer pair grows flat along the ground while the other pair faces toward the sky.
