''Astroloba herrei'' is a small, rare succulent plant of the Astroloba genus, restricted to a small area of the Karoo, on the border between the Western and Northern Cape, South Africa. It is listed as a Vulnerable species on the Red List of the South African National Biodiversity Institute (SANBI).〔(【引用サイトリンク】title=Red List of South African plants: Astroloba herrei Uitewaal )〕 ==Description== ''Astroloba herrei'' is a compact ''Astroloba'' species, with stems growing up to 20cm high, that are densely covered in pointed succulent leaves. Flowers appear from June to November. With its grey-green keeled leaves in 5 rows, the species is easily mistaken for the closely related ''Astroloba spiralis'' species but is genetically distinct. Compared to ''spiralis'', ''Astroloba herrei'' also has a smooth perianth and fine dark longitudinal lines below the surface of the leaves. Leaves are finely striate and feature narrowly acuminate leaf tips that spread outwards more strongly than in ''spiralis''. A variety of this plant was previously recognised as a separate species, ''Astroloba dodsoniana'' (Uitewaal). The dark longitudinal stripes of this variety of ''herrei'' are faded almost entirely, and the leaves appear whitish in the full sun.〔U.
