Astroloba rubriflora (L.Bolus) Gideon F.Sm. & J.C.Manning can be distinguished by its matt blue-green leaves; by its relatively small divergence angle that causes the five leaf ranks to arrange either vertically or to spiral in the direction of the generative spiral; the long red secund flowers with red to orange lobes, and perianth segments that are not inflated next to midrib and smooth to the touch. It occurs in nutrient-poor soils on rocky slopes or flats and karroid hills in the Robertson Karoo region of the Western Cape. This species flowers in summer, from December to April.
