On a visit to South Africa in 1905, Lady Phillips commissioned Rudolf Marloth to undertake his "Flora of South Africa", a mammoth work published in 6 volumes between 1913 and 1932. In 1917 a "Dictionary of the Common Names of Plants" was published - this was a supplement to the "Flora of South Africa". Other publications by Marloth were "Cape Flowers at home" (Darter, Cape Town, 1922), "The Chemistry of South African Plants and Plant Products" (Cape Chemical Society, Cape Town, 1913), "Das Kapland:insonderheit das Reich der Kapflora, das Waldgebiet und die Karroo, pflanzengeographisch dargestellt" (Gustav Fischer, Jena, 1908) and "Stone-shaped Plants" (Speciality Press, Cape Town, 1929)
