Root solid vertical, stems postrate with silvery leaves, suborbicular grayish brown, young leaves and shoots densely pubescent that have silvery appearance and flower heads solitary in axils leaves.

It is found in arid regions and on volcanic rocks in open vegetation. There is a suspected continuing decline in habitat quality due to invasive plants (Mauchamp et al. 1997).
