Gasteria carinata ("Bredasdorp Gasteria" or "Keeled Gasteria") is a small and variable succulent plant, native to the Western Cape Province, South Africa.[1]
Description

This is a highly variable species. Typically it has sharp, triangular leaves, mottled in colour and channeled on their upper surface. The leaves have sharp points at their tips, and usually have keels in mature plants. The tiny spots on the leaves are arranged in bands, giving the leaves faint stripes (similar to Gasteria batesiana).
It is proliferous and can form dense clumps.
Distribution
The natural range of this species is the southern stretch of the Western Cape Province, South Africa. Here it occurs in rocky areas in Renosterveld and Fynbos vegetation, between Hermanus and Mossel Bay.
Its closest relative is the enormous "Dune Gasteria (Gasteria acinacifolia) to the east.[2][3]
Natural variation
This is a variable species, with a range of officially defined varieties, and also with several unofficial forms - several of which have become popular ornamental cultivars.
Defined varieties
- G. carinata var. carinata: The type variety, and most common one.
- G. carinata var. verrucosa: (limestone in southern coast) Distichous leaves, with dense white tubercles
- G. carinata var. glabra: (east of Gouritz river) Rosettes of smooth glabrous triangular leaves.
- G. carinata var. thunbergii: (on the Gouritz river) Thin, upright, pointed, deeply-channeled leaves. Sometimes considered a separate species, Gasteria thunbergii.[4]
- G. carinata var. retusa: (to the north-west near Worcester) Distichous, oblong, erect-spreading leaves. It resembles Gasteria disticha and Gasteria brachyphylla, but can be distinguished by the presence of tubercles on its undulate-margined leaves. Sometimes considered a separate species, Gasteria retusa.[5]
Undefined forms
- "Melkbos" is a large, tubercled form
- "Kykoedie" is a small, compact, tubercled form, with fat, triangular leaves only 60mm long.
- "Mossel Bay" is an eastern, proliferous, smooth form, with spots in bands on its strap-shaped leaves
- "Groot Brak" is a similar eastern, proliferous, smooth form, with fainter spots
- "Klein Brak" has long triangular leaves with faint spots
