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.
