Radial spines: 7-12, grey with dark tips or black, at least at bases and tips, to 10 mm long.
The most identifying feature is their remarkable ability to live smoothly in places where there is a lot of drought. They are columnar-like with stems that have sharp spines, pronounced ribs and large flowers.
