GGr, HNF, OtP, VVP, WaP. Also WA (where possibly introduced), NSW. Mostly on heavy clay soil near salt lakes on volcanic plain, but with outlying records from near Lake Omeo (in 1940 &1981) and the Grampians (in 1893).

Note that grazing may lead to spine-like remnants on other species. Such artefacts were used to distinguish Lepidium dubium, now referable to L. hyssopifolium.
