Council of Heads of Australasian Herbaria
Apart from spasmodic records by visiting Melbourne naturalists, the vast Murray Mallee was not properly described until Chief Forester W. J. Zimmer's Flora of the Far North-West of Victoria, published by the Forests Commission in 1937. Mr. Zimmer worked the country from Hattah to the South Australian border and north to the Murray during his ten-year residence at Mildura; he has classified all his species (almost 500 vascular plants) on an ecological basis, the vegetational types being closely correlated with soil profiles.
