[2] Other less reliable ways of identifying A. herrei are the fine, dark, longitudinal lines (striations) which are sometimes visible below the surface of the leaves, and the slight blueish colour which herrei attains in sheltered or shaded environments.

Leaves often feature narrowly acuminate leaf tips that spread outwards more strongly than in spiralis.

The dark longitudinal stripes of this variety of herrei are faint or even invisible, and the leaves are slightly paler.

In 2017 its distribution was revised when it was found to be widespread in the more remote areas north of the Swartberg mountains.

In habitat, it grows on Karoo flats, often underneath bushes which provide it with some protection from the sun.
