EGL, VAlp. Apprently restricted to the upper catchment of the Buchan River, where known from three stands. Occurs in shallow rocky soils with mallee eucalypts.

Closely resembles Hakea lissosperma and H. microcarpa. Distinguished from both these species by its suckering habit, and from the latter by its densely hairy rachis and consistently terete leaves.

Hakea asperma is known to only reproduce asexually via root-suckers.
