Scattered mostly across northern and western Victoria on a variety of soils, in pastures, disturbed ground and along watercourses and road verges.
As with M. truncatula, the varieties of Heyn (1963) are rejected by Lesins & Lesins (1979). The Australian material is very variable and displays a wide range of pod shape and spine length.
