|Astroloba foliolosa in cultivation|
They are very closely related to the Haworthia genus, but are distinguished by their flowers being regular and not double-tipped. The flowers are small and white, and appear clustered on slender racemes.
They bear very regular, sharp, triangular, succulent leaves along their symmetrical columnar stems. They are slow growing, multi-stemmed, and their longer stems tend to sprawl in their rocky natural habitat.
Distribution and habitat
These species are restricted to the dryer inland regions of the southern Cape, South Africa. In their arid natural habitat, they tend to favour semi-shade positions, with well-drained soil and winter rainfall.
- Astroloba bullulata (Jacq.) Uitewaal
- Astroloba hallii (Roberts Reinecke) is sometimes classed within this species.
- Astroloba congesta (Salm-Dyck) Uitewaal
- Astroloba deltoidea is usually classed within this species.
- Astroloba corrugata N.L.Mey. & Gideon F.Sm. (also known as Astroloba aspera)
- Astroloba foliolosa (Haw.) Uitewaal
- Astroloba robusta is sometimes classed within this species.
- Astroloba herrei Uitewaal (also known as Astroloba dodsoniana)
- Astroloba rubriflora (L.Bolus) Gideon F.Sm. & J.C.Manning (also known as Poellnitzia rubriflora)
- Astroloba spiralis (L.) Uitewaal
- Astroloba pentagona is usually classed within this species.
Another possible species is Astroloba smutsiana (Roberts Reinecke)
Natural hybrids of these species occur, and there are several varieties which are unresolved as to whether they constitute intermediate forms, hybrids or separate species. In addition there are naturally-occurring hybrids between species of Astroloba and Tulista (Haworthia Robustipedunculares), including the well-known ones named Astroloba/Astroworthia bicarinata and Astroloba/Astroworthia skinneri which are separate crosses between Astroloba corrugata and Haworthia maxima.
