Gonialoe sladeniana is a species of plant in the genus Gonialoe . It is endemic to arid areas of central Namibia.
The small, stemless rosettes produce suckers that offshoot from the root, which can eventually form dense clumps. The sharp, triangular green leaves point slightly upwards and form three rows. The leaves are covered in linear white spots, and their narrow white cartilaginous margins are finely notched. Tall, very thin inflorescences appear in January and February, with small sparse pale pink flowers.
Taxonomically, it was formerly part of the Serrulatae series of very closely related Aloe species, together with Aloe variegata and Aloe dinteri . Recent phylogenetic studies have shown these three species to possibly constitute an entirely separate genus, with the name Gonialoe . [1]
While this species looks rather similar to its two sister species, it can be distinguished from Gonialoe dinteri by its shorter, straighter, less recurved leaves; and it can be distinguished from Gonialoe variegata by its taller thinner sparser inflorescence, by its having far fewer leaves, and by the spots on its leaves being more linear, almost to the point of being stripes. [2]
The species is endemic to central Namibia, south-west of Windhoek. Here its habitat is rocky quartzite in granite hills & shrubland.
This is an arid region of intermediate rainfall, between the winter-rainfall regions to the south, and the summer rainfall areas to the north. In a gradation of the three sister species, to the north Gonialoe dinteri gradually takes over in the summer rainfall areas. To the south it makes way for Gonialoe variegata in the winter rainfall regions. [3] [4] [5]
Haworthia is a large genus of small succulent plants endemic to Southern Africa (Mozambique, Namibia, Lesotho, Eswatini and South Africa).
Aloidendron dichotomum, formerly Aloe dichotoma, the quiver tree or kokerboom, is a tall, branching species of succulent plant, indigenous to Southern Africa, specifically in the Northern Cape province of South Africa, and parts of Southern Namibia.
Gonialoe variegata, also known as tiger aloe and partridge-breasted aloe, is a species of flowering plant in the family Asphodelaceae. It is an evergreen succulent perennial indigenous to South Africa and Namibia. It is common in cultivation.
Aloe arborescens, the krantz aloe or candelabra aloe, is a species of flowering succulent perennial plant that belongs to the genus Aloe, which it shares with the well known and studied Aloe vera. The specific epithet arborescens means "tree-like". Aloe arborescens is valued by gardeners for its succulent green leaves, large vibrantly-colored flowers, winter blooming, and attraction for birds, bees, and butterflies.
Gonialoe dinteri, the Namibian partridge aloe, is a species of flowering plant in the Asphodelaceae family. It is native to arid areas of Angola and Namibia.
Aloe erinacea is a rare species of succulent plant in the genus Aloe, from arid areas of Namibia.
Aloidendron pillansii, formerly Aloe pillansii, the giant quiver tree or bastard quiver tree, is a large, branching species of succulent plant indigenous to southern Africa. It is regarded as critically endangered.
Aloe viridiflora is a species of plant in the genus Aloe. The species is endemic to Namibia with a wide range and is known from at least six different populations. Current trends are not known and the species is listed as LC on the IUCN Red List. However, it is scarce and Namibian authorities consider it threatened; the plant must not be removed or disturbed. It is the only known green-flowering aloe. Its natural habitats are dry savanna, subtropical or tropical dry shrubland, and rocky areas. It can produce hallucinations when ingested, leading to its occasional use in shamanic rituals.
Aloe maculata, the soap aloe or zebra aloe, is a Southern African species of aloe. Local people in South Africa know it informally as the Bontaalwyn in Afrikaans, or lekhala in the Sesotho language.
Namaqua National Park is a South African national park situated approximately 495 km north of Cape Town and 22 km northwest of Kamieskroon. It has an area of more than 1300 km2. The park is part of Namaqualand, an area covering 55,000 km2 located within the semi-desert Succulent Karoo biome. This biome is a biodiversity hotspot with the largest concentration of succulent plants in the world. The park also has an arid environment with succulent plants. The park was created to protect its flowers. During the spring, wildflowers bloom there in a spectacular fashion. The park's main tourist attraction is this abundant spring bloom of brightly coloured wildflowers.
Kumara plicatilis, formerly Aloe plicatilis, the fan-aloe, is a succulent plant endemic to a few mountains in the Fynbos ecoregion, of the Western Cape in South Africa. The plant has an unusual and striking fan-like arrangement of its leaves. It may grow as a large multistemmed shrub or as a small tree. It is one of the two species in the genus Kumara.
Aloiampelos gracilis, formerly Aloe gracilis, the rocket aloe, is a succulent plant, endemic to dry thicket vegetation around the city of Port Elizabeth, South Africa. Its natural range lies just to the west of the related Aloiampelos ciliaris, and it occurs in bushy fynbos and dry thickets, and clustered on rocky outcrops at all altitudes. Its range extends westwards into the Baviaanskloof mountains.
Aloiampelos, formerly Aloe ser. Macrifoliae is a genus of succulent plants in the subfamily Asphodeloideae, comprising seven species found in Southern Africa. They are typically multi-branched climbing or sprawling shrubs, with long spindly stems and a large woody base on the ground. These characteristics, as well as their soft, narrow, triangular leaves whose lower part ensheathes the stem, make them easy to distinguish.
Aloe pearsonii is a very distinctive and unusual species of aloe, that is naturally endemic to the arid Richtersveld area on the border between South Africa and Namibia.
Aloe rupestris is an arborescent aloe indigenous to summer-rainfall areas of southern Africa.
× Gasteraloe (× Gastrolea) is a genus of hybrid plants, from mixtures of species from the Aloe or Aristaloe and Gasteria genera. Since most species in the genus originated as hybrids, the genus is sometimes called a "nothogenus".
Gonialoe is a small genus of three succulent plant species—Gonialoe dinteri, Gonialoe sladeniana and Gonialoe variegata—endemic to coastal South Africa, Namibia and Angola. They were formerly included within the larger, related genus Aloe.
Aloeae is a tribe of succulent plants in the subfamily Asphodeloideae of the family Asphodelaceae, consisting of the aloes and their close relatives. The taxon may also be treated as the subfamily Alooideae by those botanists who retain the narrower circumscription of Asphodelaceae adopted prior to the APG III system. Typically, plants have rosettes of more or less succulent leaves, with or without a distinct stem. Their flowers are arranged in racemes and tend to be either small and pale, pollinated by insects, or larger and more brightly coloured, pollinated by birds. As of 2017, 11 genera are recognized, most created since 2010 by splitting off another five genera from Aloe and another two from Haworthia. Only two genera, Aloe and Aloidendron, are native outside southern Africa, extending northwards to the Arabian Peninsula. Seven genera are restricted to South Africa, some with small ranges. Members of the Aloeae are cultivated by succulent plant enthusiasts; Aloe species especially are used in temperate climates as ornamental garden plants. Some species are used in traditional medicine. Aloe vera and Aloe ferox are cultivated for their extracts, whose uses include moisturizers and emollients in cosmetics.
Aloe volkensii is a species of plant widely distributed in East Africa.
× Gonimara is a genus of hybrid plants, from a mixture of species from the Gonialoe and Kumara genera. Only a single hybrid is recorded for this mixture however, × Gonimaracorderoyi, an unusual and reputedly very attractive aloe hybrid, recorded as being produced by pollination between Gonialoe variegata and Kumara plicatilis.
