MuM, VRiv, RobP. Also WA, SA. Very rare in Victoria, restricted to limestone soils in far north-west Victoria ('Boundary Point' near South Australian border, Werrimull, and the Red Cliffs-Cardross area).
This species is usually characterised by its subglabrous, dark green fruits with a raised centre, by its grey-blue leaves and by its occurrence in limestone areas.
