Haworthiopsis scabra, formerly Haworthia scabra, is a species of flowering succulent plant from arid regions of the Western and Eastern Cape Provinces, South Africa. [2]

Contents

Description

Haworthiopsis scabra is a very variable species, with several very distinct varieties. Its name "scabra" means "rough", but only its type-variety truly has rough leaves. It typically grows its leaves in three tiers (trifarious) though some varieties have five-tier leaf arrangement. Many varieties have a spiral twist to their leaves. [2]

Varieties

As of May 2024, Plants of the World Online accepted five varieties: [3]

The flowers typically appear in November and December.

Taxonomy

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. [5] [6]

Distribution

This species extends across the southern part of South Africa in the arid Little Karoo region. Here it grows on both sides of the border between the Western and Eastern Cape Provinces, from Ladismith in the West to Baviaanskloof in the East.

Within this range, it typically grows in very well-drained sandy soil, usually under a bush or rocks which serve as partial protection from the sun.

Cultivation

It is very slow growing and is not common in cultivation. It requires extremely well-drained soil and minimal water. They thrive in shady conditions, though some varieties such as starkiana can be adjusted gradually to full sun.

<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.

<i>Haworthia reticulata</i> Species of plant

Haworthia reticulata is a species of succulent plant native to the southwestern Cape Provinces of South Africa. The species has several varieties, including var. hurlingii which is the smallest at up to 1 inch (2.5 cm) wide.
