Astroloba bicarinata (Haw.) Uitewaal
Two-keeled astroloba
Astroloba bicarinata is a compact rosette succulent from the Little Karoo (Western Cape, South Africa), distinguished by its leaves with two pronounced longitudinal keels on the abaxial surface, a feature that gives it its specific name. Its 5 spiral ranks of triangular, blue-green leaves make it a gem for collectors.

"The two pronounced keels on the leaf underside are the most reliable diagnostic feature for identifying this species. The genus name Astrolista used in some Wikimedia records refers to an interspecific hybrid, not the type species."
