Haworthiopsis viscosa, formerly Haworthia viscosa, is a species of flowering succulent plant from the Western and Eastern Cape Provinces, South Africa.
Haworthiopsis viscosa typically grows its sharp succulent leaves in three tiers or columns ("trifarious" leaf arrangement). The pointed leaves are scabrous ("viscosa" means "sticky") and packed densely along its stems.
The plant offsets from its base and can eventually form large clumps. In the wild, it often shows damage from grazing animals, as it is a common food source.
The flowers appear from October to November.
This is a relatively variable species, and several regional varieties are recognised. H. beanii and H. tauteae are possible variants. H. viscosa var. variabilis is a variety with variable leaf-length, from the far south of the species' natural range, north-east of Joubertina.
The species was previously included in Haworthia subgenus Hexangulares. Phylogenetic studies demonstrated that subgenus Hexangulares was actually relatively unrelated to other haworthias and so it was moved to the new genus Haworthiopsis. [2] [3]
This species readily hybridises with other species of Haworthiopsis , as well as with species of Astroloba and other related genera.
This species extends across the southern part of the former Cape Province of South Africa. Its range stretches on both sides of the border between the Western Cape and Eastern Cape Provinces, encompassing the Little Karoo and the southern verges of the Great Karoo. It is also found in the Gamtoos Valley.
Within this range, it typically grows in very well-drained sandy soil, either in full sun, or under a bush or rocky crevice which serves as partial protection from the sun.
Haworthia is a large genus of small succulent plants endemic to Southern Africa (Mozambique, Namibia, Lesotho, Eswatini and South Africa).
Haworthiopsis fasciata, formerly Haworthia fasciata, is a species of succulent plant from the Eastern Cape Province, South Africa. The species is rare in cultivation; most plants that are labelled as H. fasciata are actually Haworthiopsis attenuata.
Haworthiopsis coarctata, formerly Haworthia coarctata, is a species of flowering succulent plant from the Eastern Cape Province, South Africa and naturalized in Mexico. It is one of the species of Haworthiopsis that is commonly cultivated as an ornamental.
Haworthiopsis reinwardtii, formerly Haworthia reinwardtii, is a species of succulent flowering plant in the family Asphodelaceae, native to the Eastern Cape Province of South Africa. It is one of the species of Haworthiopsis that is commonly cultivated as an ornamental.
Haworthia truncata, locally known as horse's teeth, is a species of succulent plant in the genus Haworthia. It is found in the Little Karoo region, in the far east of the Western Cape Province, South Africa.
Haworthiopsis tessellata, formerly Haworthia tessellata, is a species of the genus Haworthiopsis belonging to the family Asphodelaceae. It has been considered a subspecies of its close relative, Haworthiopsis venosa.
Haworthiopsis venosa, formerly Haworthia venosa, known in Afrikaans as venstertjie, is a species of flowering plant in the genus Haworthiopsis belonging to the family Asphodelaceae, native to Namibia and South Africa.
Haworthiopsis attenuata, formerly Haworthia attenuata, commonly known as zebra haworthia, is a small species of succulent plant from the Eastern Cape Province, South Africa. As an ornamental, it is one of the most commonly cultivated of the Haworthiopsis species.
Tulista is a small genus of succulent plants endemic to the Cape Provinces of South Africa. They were formerly included within the genus Haworthia.
Haworthiopsis nigra, formerly Haworthia nigra, is a species of flowering succulent plant from the Western and Eastern Cape Provinces, South Africa.
Haworthiopsis pungens, formerly Haworthia pungens, is a species of flowering succulent plant from the Eastern Cape Province, South Africa.
Haworthiopsis scabra, formerly Haworthia scabra, is a species of flowering succulent plant from arid regions of the Western and Eastern Cape Provinces, South Africa.
Haworthia zantneriana is a species of the genus Haworthia in the family Asphodelaceae, subfamily Asphodeloideae, endemic to the southern parts of the Western Cape and Eastern Cape Provinces in South Africa.
Haworthiopsis bruynsii, formerly Haworthia bruynsii, is a rare species of the genus Haworthiopsis in the family Asphodelaceae, endemic to a small area in the Eastern Cape Provinces in South Africa.
Haworthiopsis glauca, formerly Haworthia glauca, is a species of flowering succulent plant from the Eastern Cape Province, South Africa.
Tulista pumila ("Vratjiesaalwee") is a species of Tulista succulent plant, from the Western Cape, South Africa.
Tulista kingiana is a species of succulent plant, from the Western Cape, South Africa. It is listed as Endangered on the IUCN global Red List.
Tulista minor is a species of succulent plant, from the far south of the Western Cape, South Africa.
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.
Haworthiopsis is a genus of succulent plants in the subfamily Asphodeloideae. The genus was previously included in Haworthia. Species in the genus are typically short perennial plants, with leaves often arranged in a rosette and frequently having raised white markings. The two-lipped flowers are borne on a tall stalk and are small – less than 17 mm (0.7 in) long – and pale in colour. Many species are cultivated as house plants or by succulent enthusiasts.
