Herriott was born in Canterbury in 1882. Her parents were David and Elizabeth Susannah Herriott. Herriott attended Christchurch East School and Christchurch Girls' High School, where she was head prefect in 1899. She won a scholarship to attend Canterbury College, and studied botany and chemistry there from 1900 to 1905. She graduated with a B.A. in 1904 and a M.A. in 1905.. Her Master's research was on the leaf anatomy of Subantarctic Islands species, and involved the study of plants brought back from an expedition in 1903 by Leonard Cockayne.
Career
On graduation Herriott took up teaching positions, initially at Rangi Ruru Girls' School and later at Kaikoura District High School. In 1916 she was appointed to an assistant lecturer position in the Department of Biology at Canterbury College. She was promoted to the position of lecturer in 1928, and held this position until her retirement in 1934. Herriott was particularly interested in the unusual anatomical adaptations that plants made to better survive in harsh environments. Her published work included papers on fresh water crustacean, biographies of early botanists Joseph and John Armstrong, and the morphology of the seaweed Durvillaea. In this study she compared records of the plant life in the area in 1864 with later observations. She particularly noted the impact of land development such as the draining of a swamp in 1897 to create Lake Victoria, the introduction of non-native plants through ceremonial plantings by visiting dignitaries and the erection and destruction of buildings for the International Exhibition of 1906. From 1921 to 1927 Professor Charles Chilton, the chair of the biology department, held the position of Rector of Canterbury College, and Herriott served as his clerical assistant. Herriott was a member of the Philosophical Institute of Canterbury for many years; in 1919 she was elected to its council, and in the 1920s she served as its Honorary Librarian. Herriott was a member of the Worcester Street Brethren assembly and held Evangelical Union prayer meetings in her college office.
Death
On 13 March 1936, Herriott died at her home at St Andrews Square in the Christchurch suburb of Strowan.
