Agnes Adelaide Donaldson

Agnes Adelaide Donaldson (; 1866–1948) was an Australian botanical collector, governess, and sheep station owner. Part of the expansive network of collectors established by Ferdinand von Mueller to botanically describe and categorise the flora of Australia, she was the earliest recorded woman, and one of the earliest recorded people, to collect plant material around Alpha in Queensland.

Life Donaldson was born to pastoralists Hastings Alfred Elms (1832–1910), and Janet Beveridge Elms (1838–1899) in Smeaton, Victoria. In the late 1880s, Agnes travelled to Lansdowne, Queensland to work as a governess at Lansdowne station. She met the station overseer Robert Donaldson, and they married in 1890 and they ultimately had three daughters and three sons.

After the wedding in Victoria, the Donaldsons travelled to Alpha pastoral station in Alpha, Queensland where Robert was the manager. At this time it is claimed that he employed Breaker Morant. In 1910, this property was passed on to the Queensland pastoralist Eric Henry Mackay (1841–1923), and then his daughter Clara Miller. In 1946 she moved close to Rockhampton to receive medical treatment and died in July 1948. He therefore advertised in regional Queensland newspapers, including in Rockhampton, requesting for people to send him plant specimens. Today her specimens are cared for in the collections of the National Herbarium of Victoria, Royal Botanic Gardens Victoria.
