Haworthia bayeri is a species of the genus Haworthia in the family Asphodelaceae, endemic to the southern Cape Provinces in South Africa.
It can be distinguished from its Haworthia relatives, by its rounded leaf tips and its dark colour.
The upper leaf faces are semi-translucent. They are usually marked with longitudinal lines or reticulated patterns, rather than with spots or flecks. Rosettes are usually solitary, as the plant rarely forms offsets.
This species is variable and has multiple different regional forms:
Flowers appear in September and October. [1]
This is a "retuse" species of Haworthia and is easily confused with its relatives (e.g. Haworthia pygmaea , Haworthia retusa , Haworthia springbokvlakensis , Haworthia mirabilis , Haworthia emelyae and Haworthia magnifica ).
A western form, inhabiting shale rocks near Oudtshoorn, is sometimes considered a separate species, Haworthia truteriorum . It is smaller, dull-green, with silver lines or flecks on its leaves, which have more strongly toothed margins. [2]
An outlying population of similar plants in the Rooinek Pass, south of Laingsburg, is now usually classed as a separate species, Haworthia marxii .
The natural range of this species is in the arid Little Karoo area around the boundary between the Western Cape and the Eastern Cape Provinces, South Africa. Here is occurs roughly between Oudtshoorn in the west and Uniondale in the east. This is an arid summer rainfall region. In the east of its range, the plants have a rougher, more scabrid leaf surface.
It grows easily in cultivation, but requires very well draining soil. It can be propagated by leaf cuttings and seed, as it rarely offsets.
It is threatened by illegal collection for the horticultural trade, as well as habitat destruction. Populations have therefore suffered considerable decline. [3]
Haworthia is a large genus of small succulent plants endemic to Southern Africa (Mozambique, Namibia, Lesotho, Eswatini and South Africa).
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.
Haworthia magnifica is a species of the genus Haworthia belonging to the family Asphodelaceae.
Haworthia mirabilis is a species of the genus Haworthia belonging to the family Asphodelaceae.
Tulista is a small genus of succulent plants endemic to the Cape Provinces of South Africa. They were formerly included within the genus Haworthia.
Robertson Karoo is a semi-arid vegetation type, restricted to sections of the Breede River Valley, Western Cape Province, South Africa. It is a subtype of Succulent Karoo and is characterised by the dominance of succulent plant species, and by several endemic plants and animals.
Haworthia retusa is a species of flowering plants of the genus Haworthia in the family Asphodelaceae, endemic to a very small area around Riversdale, in the Western Cape Province in South Africa. Growing to 10 cm (3.9 in) tall and broad, it is a perennial succulent with thick triangular leaves and small white tubular flowers held in 50 cm (20 in) tall racemes.
Haworthia mucronata is a species of the genus Haworthia in the family Asphodelaceae, endemic to the Little Karoo region, in the Western Cape Province of South Africa.
Haworthia emelyae is a species of the genus Haworthia in the family Asphodelaceae, endemic to the Western Cape Province in South Africa.
Haworthia pygmaea is a species of the genus Haworthia in the family Asphodelaceae, endemic to the Mossel Bay area of the Western Cape, South Africa.
Haworthia springbokvlakensis is a species of the genus Haworthia in the family Asphodelaceae, endemic to a very restricted area of the Eastern Cape Province in 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.
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 viscosa, formerly Haworthia viscosa, is a species of flowering succulent plant from the Western and Eastern Cape Provinces, South Africa.
Haworthia arachnoidea, locally known as "papierrosie" (paper-rose) or "spinnekopnes" (spider-nest), is the type species of the genus Haworthia, in the family Asphodelaceae, in the Western Cape Province of 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 marginata is a species of Tulista succulent plant, from the Western Cape, South Africa.
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.
