Detail of the densely hairy stems of An. filamentosa.
This plant forms clusters of tiny stems, each covered in densely-packed, round leaves.
Each leaf is almost a sphere in shape, but has a tiny, down-turned "chin" at its tip. The leaves, and the entire plant, are covered in a dense coat of hair, giving it a white colour. Additionally, a few longer, bristly hairs extend further out (though in the northern part of its range, the namaquensis subspecies has shorter bristles that do not extend further than the leaves).
