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 .

Etymology

The genus name Haworthiopsis means "like Haworthia", which honors the British botanist Adrian Hardy Haworth (1767–1833), while the species Latin epithet tessellata means "square-patterned".

Description

Haworthiopsis tessellata is a succulent evergreen slow-growing species reaching a size of 15 cm in height. It is a stemless plant, with square patterned leaves on the upper surfaces and small teeth along the margins. The leaves are greenish, form a rosette and turn to reddish in full sun. The flowers are white and small, in an inflorescence.

It is extremely closely related to Haworthiopsis granulata (restricted to the far south-west of its range near Laingsburg) and to Haworthiopsis venosa (a species restricted to a spot on the south coast of South Africa).

Distribution and habitat

This widespread species can be found in the arid hinterland of South Africa. Its habitat is the dry, summer-rainfall Karoo, where it grows within bushes and in rocky areas. It occurs as far north as southern Namibia.

Asphodeloideae is a subfamily of the monocot family Asphodelaceae in the order Asparagales. It has previously been treated as a separate family, Asphodelaceae sensu stricto. The family Asphodelaceae has now been proposed to be a nomen conservandum, and the proposal has been recommended for ratification in 2017. In that case, Asphodelaceae will have priority over Xanthorrhoeaceae. This is reflected in the APG IV family lists.

<span class="mw-page-title-main">Aloeae</span> Tribe of succulent plants

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.

<i>Haworthiopsis</i> Genus of succulent plants

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.
