subsequently abolished Guilfoylia as part of the genus of Cadellia in his botanical census of 1882 (today the genus Guilfoylia is again accepted). Guilfoyle went on to landscape the gardens in an aesthetic and pleasing style welcomed by most Melburnians. In 1857, Mueller applied for and was granted the degree of Doctor of Medicine of the University of Rostock; in 1883, he was awarded the Clarke Medal by the Royal Society of New South Wales. He published 11 volumes of Fragmenta phytographiae Australiae (1862–1881), two volumes of the Plants of Victoria (1860–1865), and other books on the Eucalyptus, Myoporaceae, Acacia, and Salsolaceae, all profusely illustrated. He also co-operated in the production of George Bentham's Flora Australiensis. He described many novel plant species sent by botanists from other parts of Australia, notably Maurice William Holtze from the Northern Territory, and encouraged settlers to send plants to him. Women were key contributors to his collections. Two hundred twenty-five women and girls, the youngest of which was six years of age, collected plant specimens and mailed them to Mueller for cataloging. These women included Louisa Atkinson, Sarah Brooks, and Flora Mary Campbell. He took a leading part in promoting Australian exploration, especially the Burke and Wills expedition, which was the first to cross the continent, and in the various attempts to unravel the mystery which attended the fate of his fellow countryman Ludwig Leichhardt (1813–1848). Mueller died in Melbourne and is buried in the St Kilda Cemetery. He was survived by his sister, Mrs. Clara Wehl, of Millicent, South Australia. His other sister, Mrs. Bertha Doughty of near Penola predeceased him. He never married. Mueller was a theist who rejected Darwinism, but is said by historians to have misunderstood key aspects of Charles Darwin's theory. Despite his differences he remained on friendly terms with Darwin.
