Margaret Lilian Flockton (29 September 1861 Sussex – 12 August 1953 Sydney), is most commonly recognized as a botanical artist famous for her botanical illustrations of "The Forest Flora of New South Wales" (some 300 plates), "A Critical Revision of the Genus Eucalyptus", and the genus Opuntia, all by the botanist and forester, Joseph Henry Maiden. She was also a painter, commercial artist, and art teacher at different points of her life. She was the first botanical illustrator at the Royal Botanic Gardens in Sydney.[1] She was also the first female lithographer in Australia which gave her a high reputation at the time.
