Astroloba spirella (Haw.) Molteno & Gideon F.Sm. can be distinguished by its leaves that are matt and smooth, without tubercles, though often with some longitudinal striations near the leaf tips; by its relatively large divergence angle (±144°–151°) arranging the leaves in five ranks that appear either vertical or spiralling in the same direction as the generative spiral; the flowers with white lobes, and perianth segments that are not inflated next to midrib and smooth to the touch. It occurs in shrubby vegetation on rocky slopes in the western Little Karoo. This species flowers in late summer, from January to March.
