Herbert Stanley Morris, though born in Australia, attended school in Bedford, Eastern Cape and passed the matriculation examination of the University of the Cape of Good Hope in 1906. He then studied at the South African College, Cape Town, from 1907 to 1909 and in the latter year was awarded the degree Bachelor of Arts (BA) with honours in botany by the University of the Cape of Good Hope. He remained associated with the Department of Botany at the South African College for the next year or two, during which time he published two papers: "Note on an abnormal seedling of Widdringtonia cupressoides and a brief account of the vascular system of the normal seedling" (with E.P. Phillips*, Transactions of the Royal Society of South Africa, 1908-1910, Vol. 1, pp. 411-412), and "Observations on the stem structure of Hemitelia Capensis" (a species of tree-fern, Report of the South African Association for the Advancement of Science, 1909, pp. 119-122). He was not a member of either of these organisations. His botanical notebooks (1907-1909), containing small botanical sketches, were donated to the libraries of the University of Cape Town.
Morris subsequently became District Commissioner for Fiji and aide-de-camp to the Governor. During World War I (1914-1918) he joined the Royal Flying Corps and attained the rank of second lieutenant. He was killed in an aircraft accident in England in 1919 and was survived by his wife, Sylvia Ena de Creft-Harford, and two daughters.
