Kumara is a genus of two species of flowering plants in the subfamily Asphodeloideae, native to the Western Cape Province of South Africa. [2] [3]

Separation from Aloe

Phylogenetic studies indicated that two species that were traditionally classed as members of the genus Aloe were genetically distinct and comprised an entirely separate clade. The species were accordingly split off as a separate genus, given the name that it had previously held, Kumara. [4] Both species bear characteristically strap-shaped leaves in a two-ranked (orthodistichous) arrangement. [5]

Intergeneric hybrids have nonetheless been recorded, between Kumara and at least one other alooid genus, Gonialoe . The resulting hybrid, initially published as an infrageneric hybrid between two species of Aloe , is now designated an intergeneric hybrid of the new nothogenus ×Gonimara. [6]

Species

Two species are accepted, as of October 2017: [1]

Both species have a unique distichous ("fan") arrangement to their grey, strap-shaped leaves. Both are also indigenous to roughly the same range of mountains in the south-western corner of the Western Cape, South Africa, however the tall tree-like Kumara plicatilis is found on the lower slopes of the mountains, while the tiny stemless Kumara haemanthifolia inhabits the high peaks.

<i>Aloe</i> Genus of succulent flowering plants

Aloe, also written Aloë, is a genus containing over 560 species of flowering succulent plants. The most widely known species is Aloe vera, or "true aloe". It is called this because it is cultivated as the standard source for assorted pharmaceutical purposes. Other species, such as Aloe ferox, are also cultivated or harvested from the wild for similar applications.

Asphodeloideae Subfamily of flowering plants, in monocot family Asphodelaceae

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.

Aloeae 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>Aloidendron</i> Species of plant in the family Asphodelaceae

Aloidendron is a genus of succulent plants in the subfamily Asphodeloideae. It was split off from the much larger genus Aloe in 2013.

<i>Haworthiopsis</i> Genus of succulent plants in the family Asphodelaceae/Xanthorrhoeaceae

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.

× 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.
