Astroloba deltoidea (Hook.f.) Uitewaal
Delta-shaped astroloba
Astroloba deltoidea is a succulent from the Western Cape of South Africa characterized by its very pronounced deltoid (triangular) leaf shape, with marked leaf angles and a wide base. It forms dense rosettes with the 5 spiral ranks typical of the genus. Its taxonomy has historically been linked to A. congesta, from which it is distinguished by the more clearly deltoid leaf profile.
