The leaves are a glossy green in colour, concave on their upper faces, smooth, sharp with slight keels, and point upwards and outwards.

Like its closest relatives - Astroloba foliolosa and robusta, it produces cream-white flowers in the rainy season (September–January in habitat), tinged with green, on unusually short pedicels.

It is easily confused with its close relative to the west, Astroloba foliolosa, and the two species form a transition.

This is an area of relatively high rainfall, 300–450 mm, which falls predominantly in the summer.

[3] This smaller form, from rocky areas of the Zuurberg mountains, was previously classed as a separate species, Astroloba deltoidea.
