Introduction
The species in this section have leaves that are matt and unadorned. The inflorescence is usually unbranched, and the flowers have somewhat inflated perianth tubes. The preferred habitat of both species is low, gentle slopes or flat plains usually comprised of rocky alluvium, on both the north and south sides of the Groot Swartberg mountain range.
Species
Astroloba herrei Uitewaal can be distinguished by its leaves that sometimes have faint longitudinal lines; by its relatively small divergence angle that causes the five ranks of leaves to spiral counter to the direction of the generative spiral; the inflorescence that is unbranched, and the flowers that are born on very long pedicels, with yellow lobes, and perianth segments that are inflated next to the midrib and fairly rough to the touch. It occurs in karroid vegetation both north and south east of the Groot Swartberg Mountains in the Western Cape. This species flowers in late spring, from October to November.
Astroloba spiralis (L.) Uitewaal can be distinguished by its unadorned leaves (sometimes with very faint longitudinal lines); by its relatively large divergence angle, which causes the five ranks of leaves to spiral in the same direction as the generative spiral; the flowers with yellow lobes, and perianth segments that are wrinkled and inflated next to midrib and rough to the touch. It occurs in karroid vegetation south of the Groot Swartberg Mountains in the Oudtshoorn basin in the Western Cape. This species flowers in early summer, November.
