''Haworthia kingiana'' is a species of ''Haworthia'' succulent plant, from the Western Cape, South Africa. It is listed as Endangered on the IUCN global Red List ==Description and taxonomy== It is an evergreen succulent plant with short, sharp, bright green leaves arranged in rosettes. The yellowish-green leaves have rounded, flat, white tubercles (though in some varieties these are absent). The plant gradually produces offsets, and can form clumps. In November and December it produces pink-white flowers. ''Haworthia kingiana'' is a variable species, with different populations and varieties, differing in the leaf shape, colour, growth form and tubercles. Among ''Haworthia'' species it is classed with the other large species (''H.maxima'', ''H.minima'' & ''H.marginata'') in the ''"Robustipedunculares"'' subgenus. Following recent phylogenetic studies, it has been shown that these four species in fact constitute a distinct out-group, separate from other Haworthias. It has therefore been proposed to class them as a separate genus, ''"Tulista"''.〔Manning, J.C., Boatwright, J.S., Daru, B.H., Maurin, O. and Van der Bank, M. 2014.
