A list of Sargant's publications is provided in an article in the Journal of the Society for the Bibliography of Natural History. She worked with
Margaret Jane Benson, head of the Department of Botany at
Royal Holloway College, and travelled with her throughout Europe in 1897 to acquire equipment and knowledge to set up that school's laboratory. From 1892 to 1893, she worked with
Professor D.H. Scott at the
Jodrell Laboratory in
Kew Gardens, where she investigated the nucleus and the development of the male and female gametes in
Lilium martagon . For the following years she specialised in seedling anatomy, giving a course of lectures on botany at the
University of London in 1907. In December 1904, Sargant was elected one of the first women to become a fellow of the
Linnean Society of London, and she also became the first female on their council. After the deaths of her mother and sister, she moved to live at the Old Rectory in
Girton village in 1912. ==After death==
