Gonialoe (the partridge aloes) is a small genus of three succulent plant species—Gonialoe dinteri, Gonialoe sladeniana and Gonialoe variegataendemic to coastal South Africa, Namibia and Angola. They were formerly included within the larger, related genus Aloe.{{cite web|url=http://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:77142514-1|title=Gonialoe (Baker) Boatwr. & J.C.Manning | Plants of the World Online | Kew Science|website=powo.science.kew.org|accessdate=2017-09-15}}

Taxonomy

The genus Aloe was found to be polyphyletic. It was accordingly divided into different genera: Aloe, Kumara, Aloiampelos, and Gonialoe, among others. Several recent phylogenetic studies have confirmed this division, and shown that Aloe actually consists of several relatively unrelated groups.

The same studies suggested that the closest relatives of this proposed genus were the related genera Astroloba and Tulista.Manning, John; Boatwright, James S.; Daru, Barnabas H.; Maurin, Olivier; van der Bank, Michelle.

The three species of this genus can easily be recognised by their compact, triangular leaves forming three vertical or spiraling ranks (trifarious).Molteno, S.
