Flora Australiensis is a seven-volume flora of Australia published between 1863 and 1878 by George Bentham, with the assistance of Ferdinand von Mueller. It was the first flora of any large continental area that had ever been finished, and was the standard reference work on the Australian flora for more than a century. As late as 1988, James Willis wrote that "Flora Australiensis still remains the only definitive work on the vascular vegetation of the whole continent." According to Nancy Burbidge, "it represents a prodigious intellectual effort never equalled." — Excerpted from Flora Australiensis on Wikipedia, the free encyclopedia.
