Taxonomy
Trachymene glaucifolia(F. Muell.) Benth. was collected last century near the Victoria–NSW border from the junction of the Murray and Darling Rivers
It is generally distinguished from glabrous and glaucous forms of Trachymene composita by its bluish flowers, and in the development of only 1 mericarp from each pair
