Tulista kingiana (Poelln.) Gideon F.Sm. & Molteno (= Haworthia kingiana Poelln.)

Plants form a stemless rosette, with erect to spreading, yellowish green leaves. Rosettes can be up to 180 mm tall, but are usually smaller than this, and occasionally form few-headed clusters. The leaf surface is scabrid (rarely glabrous) with white to concolorous, raised, non-confluent tubercles.

This species has a narrow distribution, restricted to a few scattered populations in the vicinity of Mossel Bay, Hartenbos, Great Brak, and near Herbertsdale in the Western Cape Province, South Africa. Plants are normally found in sandy soils, and either grow exposed in grassy terrain or sheltered beneath larger shrubs on sloped rocky areas.

Tulista minor (Aiton) Gideon F.Sm. & Molteno [= Haworthia minor (Aiton) Duval; H. minima (Aiton) Haw.]

Plants form a stemless rosette, with erect to spreading, light to darker green leaves (only occasionally bluish green). Rosettes are up to 150 mm tall, and occasionally form small clusters. The leaf surface is scabrid with white, raised, flattened, non-confluent tubercles. This species is morphologically variable, with many interesting and distinct geographical forms.

This is the most widespread species in the genus. It is mainly a coastal species, and is known from near Mossel Bay in the east, to Bredasdorp in the west, and to the north of the Langeberg Mountains, Western Cape Province, South Africa. The habitat varies considerably, but it is generally found in grassy vegetation.

Haworthiopsis attenuata (Haw.) G.D.Rowley [= Haworthia attenuata (Haw.) Haw.]

The zebra plant is an attractive rosette-forming plant, with erect to spreading leaves exhibiting an array of different leaf tubercle variation. Plants range from about 50 mm to 100 mm tall and form dense clusters. The white tubercles range from fine to conspicuous tubercles, scattered over the lower leaf surfaces, or forming confluent bands reminiscent of zebra bands, hence its common name.

This species is found widespread in the Eastern Cape, from near the Gamtoos River in the west to the Mbashe River in the east. This species has 2 described varieties, var. glabrata and var. radula.

Haworthiopsis glauca (Baker) G.D.Rowley (= Haworthia glauca Baker)

This species is similar in appearance to H. coarctata and H. reinwardtii by sharing the same stemmed growth habit, but differ in having glaucous grey-coloured leaves. In most forms the plants are without distinct white tubercles, however, white tubercles are found on the leaf surfaces in plants of the var. herrei. In this species, plants also proliferate from the base and occasionally along the stem to form clumps, growing up to about 200 mm tall.

This species is found further inland than the above-mentioned and is known from relatively drier areas.

Haworthiopsis limifolia (Marloth) G.D.Rowley (= Haworthia limifolia Marloth)

This species is well suited to rockeries in summer rainfall areas. Plants form attractive rosettes of spiralling leaves, varying from being smooth to tuberculate, often with the tubercles forming confluent bands or ridges.

The only species in the genus known to occur in KwaZulu-Natal; it is also found in Mpumalanga and extending its distribution into Swaziland and possibly Mozambique. This species has become rare in its natural habitat because of over-collection for traditional purposes. Several varieties are recognised: var. arcana, var. gigantea, var. glaucophylla and var. ubomboensis.

Haworthiopsis tessellata (Haw.) G.D.Rowley (= Haworthia tessellata Haw.)

The species is best suited to containers; it has a highly stoloniferous habit and produce many plantlets to eventually form a dense mat of compact rosettes. The starry rosettes (20–80 mm in diameter) have spreading to recurved leaves, with lines and reticulations, that are windowed on the upper surface.

This species is widespread and is known from the drier interior of South Africa where it is found in the Western Cape, Eastern Cape, Northern Cape, Free State and North-West Provinces. The distribution of this species also extends into Namibia. The var. crousii is similar in appearance to the typical variety, although much more robust and less proliferous.
