Distribution and ecology

Occurs in coastal and near-coastal areas of W.A. between Geraldton and Carnarvon.


Considered by Symon (1981) to be closely related to S. centrale J. Black and S. coactiliferum J. Black, but distinguished by the slender, straight prickles and smaller leaves.

Considered by Bean (2004) to be a member of the S. esuriale group of subgen. Leptostemonum. While S. coactiliferum is also assigned to this group, S. centrale was considered by Bean to be part of the S. macoorai group.
