Asphodelaceae

Aloe

Aloe

Genus comprising over 500 accepted species, with a diversity center in southern and eastern Africa. Species range from small stemless rosettes to trees exceeding 10 meters. Succulent leaves typically have toothed margins and contain a mucilaginous gel historically used in traditional medicine. Tubular flowers, usually orange or red, are arranged in erect racemes.

Aloiampelos

Aloiampelos

Genus of scrambling or procumbent aloes segregated from Aloe. Includes the scrambling aloe species originally classified as Aloe ciliaris, among others.

Aloidendron

Aloidendron

Genus of large arborescent aloes segregated from Aloe; includes the world's largest aloe tree.

Aristaloe

Aristaloe

Monotypic genus in the family Asphodelaceae, segregated from Aloe. Contains only Aristaloe aristata, the lace aloe, one of the world's most popular ornamental succulents thanks to its finely toothed leaves with white tubercles and tubular orange flowers. Native to South Africa and Lesotho, it is more cold-hardy than most aloes, tolerating down to −7 °C. The segregation from Aloe was proposed by Boatwright and Manning based on molecular phylogenetic analyses.

Astroloba

Astroloba

Genus of small succulents in the family Asphodelaceae, endemic to the south-western Cape of South Africa. Form compact rosettes with rigid triangular leaves arranged in 5 spiral rows. Morphologically similar to Haworthiopsis, with tubular white or cream flowers. Very popular among collectors for their elegant spiral symmetry.

Bulbine

Bulbine

Genus of succulent and semi-succulent plants in the family Asphodelaceae, subfamily Asphodeloideae, with about 70 species native mainly to South Africa, Namibia and Australia. They form rosettes or clumps of fleshy lanceolate or cylindrical leaves and produce spikes of small six-petalled yellow or orange flowers with hairy stamens. B. frutescens is the most widely cultivated species, popularly known as "bulbine" and used in xeriscaping and as a medicinal plant.

Catevala

Catevala

Historical genus created by Otto Kuntze (1891) as a replacement name for Haworthia Duval. All taxa are heterotypic synonyms of Haworthia species. Plants are rosulate succulents belonging to subfamily Asphodeloideae, native to South Africa and endemic mainly to the Cape region.

Gasteria

Gasteria

Genus of succulents endemic to South Africa, with about 23 accepted species. They are characterized by thick leaves, distichous (arranged in two rows) or rosulate, frequently with rough texture and white spots. The tubular, curved flowers with an inflated base resemble a stomach, giving the genus its name (from Latin "gaster"). They tolerate partial shade better than most succulents.

Guillauminia

Guillauminia

Genus of succulents in family Asphodelaceae, endemic to Madagascar. Plants with dense aloe-like rosettes, often small-sized. P.V. Heath's 1994 treatment; modern flora (Plants of the World Online) synonymises most into Aloe.

Haworthia

Haworthia

Genus of succulents in family Asphodelaceae, native mainly to southern Africa (South Africa, Namibia, Eswatini). Small to medium plants forming dense rosettes, frequently with translucent windows on leaf tips. One of the most popular houseplant succulents worldwide.

Haworthia

Haworthia

Genus of small succulents native to South Africa, with approximately 150 accepted species (sensu lato). They are characterized by compact rosettes of firm leaves, often with translucent markings called "windows" that allow light to enter the leaf interior. They grow in shaded environments among rocks and under shrubs, adapted to low direct light.

Haworthiopsis

Haworthiopsis

Haworthiopsis is a genus of dwarf succulents from southern Africa, segregated from Haworthia in 2013 on the basis of molecular phylogenetic studies. Its members bear small rosettes of fleshy leaves with a thicker, tougher epidermis than their close relatives, enabling survival through prolonged drought and even fire. The flowers are bilabiate, white or whitish with dark central veins, borne on slender erect inflorescences. The centre of diversity lies in South Africa's Eastern Cape Province, where ten of the genus's nineteen species are endemic.

Kumara

Kumara

Genus of succulents in the Asphodelaceae family, segregated from the genus Aloe. It comprises few species of succulent shrubs with rosette or fan-shaped leaves, endemic to the Cape region of South Africa. It is valued both for its ornamental value and its ecological importance in the fynbos.

Kumaria

Kumaria

Genus of succulents in the Asphodelaceae family, related to Haworthia and Aloe. It comprises small to medium-sized rosette plants, with fleshy leaves frequently translucent at the apex. They are shade or semi-shade plants of the South African Cape habitat.

Lemeea

Lemeea

Genus of succulents in the Asphodelaceae family, related to Aloe and established by P.V. Heath to group certain haworthioid-looking species from Madagascar. They are small to medium-sized rosette plants with translucent fleshy leaves, adapted to the shaded understory of Madagascar.

Leptaloe

Leptaloe

Monotypic genus of the Asphodelaceae family, segregated from Aloe. It comprises a single small-sized aloe species with tubular pink flowers. It is endemic to northeastern Africa and the Horn of Africa, where it inhabits arid and semi-arid stony soils.

Lomatophyllum

Lomatophyllum

Genus of the family Asphodelaceae, closely related to Aloe and treated by many authors as synonymous with it. Succulent plants with rosette leaves and tubular flowers. Endemic mainly to the Mascarene Islands (Réunion, Mauritius) and Madagascar.

Pachidendron

Pachidendron

Poellnitzia

Poellnitzia

Monotypic genus of Asphodelaceae from southwestern South Africa, closely related to Astroloba and Haworthia, bearing unique red tubular flowers within that genus complex; named in honour of German botanist Max Poellnitz (1896–1945).

Rhipidodendrum

Rhipidodendrum

Historical genus of succulent plants in the family Asphodelaceae, closely related to Aloe. Known for its arborescent habit and leaves arranged in distichous fans. Native to South Africa, now treated as a synonym of Aloe.
