Winsome Fanny Barker (23 September 1907 – 27 December 1994) was a South African botanist and plant collector noted for her work as Curator building the collection at the herbarium of the Kirstenbosch National Botanical Garden, as well as her research on Amaryllidaceae, Liliaceae and Haemodoraceae.
The Suid-Afrikaanse Akademie vir Wetenskap en Kuns awarded her the Junior Captain Scott medals in both subjects as she had attained the highest marks in her class.
[2] In 1956 the South African Museum herbarium, containing 100000 specimen sheets, was transferred to Kirstenbosch on permanent loan.
In doing so the SA Museum herbarium curator, Dr Joyce Lewis and her assistant also transferred to Kirstenbosch.
Thirty-five of her illustrations were published in Flowering Plants of South Africa between 1930 and 1938, and the Royal Horticultural Society in London had a set of her watercolour images of Agapanthus.
