Born in Brisbane, Qld, on 11 February 1924.
Although a qualified medical practitioner, his main interest is in farming. Previously he had been a beekeeper and this led to an interest in the honey flora of south-eastern Queensland and collection of botanical material in the Moreton, West Moreton and Darling Downs districts of the State. Dr Stevens often collected in company with S. T. Blake.Source: Extracted from: Hall, N. (1978) Botanists of the eucalypts. Commonwealth Scientific and Industrial Research Organisation, Melbourne
