# Stephen Troyte Dunn

Stephen Troyte Dunn (26 August 1868, Bristol - 18 April, 1938, Sheen, Surrey, England) was a British botanist. He described and systematized a significant number of plants around the world, his input most noticeable in the taxonomy of the flora of China. Among the plants he first scientifically described was Bauhinia blakeana, now the national flower of Hong Kong.

## Biography

Born in Bristol in the family of Rev. James Dunn, of Northern Irish descent, S. T. Dunn was educated at Radley, and at Merton College, Oxford, where he earned his BA in classics.
He was private secretary to liberal politician Thomas Acland in 1897, and the next year (as in 1898 Thomas Acland died) he first joined Kew as private secretary to the director, W. T. Thiselton-Dyer. He was then assistant for India in the herbarium from 1901 until his departure for Hong Kong in 1903. At Kew prior to this, he worked on compiling the second supplement of Index Kewensis which was issued in 1904–1905.
While superintendent at the Department of Botany and Forestry, Hong Kong (1903–1910), Stephen Dunn would go on expeditions and make many collections in Asia, including Taiwan, Guangdong province and Fujian Province, as well as in Korea and Japan. He was especially interested in ferns.
After returning to England, he became an official guide at Kew in 1913, but left Britain again in 1915 for America. Returning four years later, he went back to the Kew Herbarium, where he remained until his retirement in 1928.
Among his published works were many articles on the Chinese flora as well as flora of Britain. He was a regular contributor to Journal of the Linnean Society.
