Bunzō Hayata

Hayata was born to a devout Buddhist family in Kamo, Niigata on December 2, 1874. When he was 16, Hayata became interested in botany, and he joined the Botanical Society of Tokyo in 1892. His schooling was delayed by a series of family tragedies, and he graduated middle school at the age of 23. He then attended high school and began to collect botanical samples.[1]

Hayata enrolled in the botany program at the Imperial University of Tokyo in 1900. He graduated in 1903, and entered the graduate program under Jinzō Matsumura. He was appointed assistant at the Koishikawa Botanical Gardens in 1904. In 1907, he completed his Doctor of Sciences degree.

In 1908, Hayata was promoted to lecturer in the Department of Botany at the Imperial University of Tokyo. Hayata undertook a botanical expedition to Tonkin in 1917, and was promoted to Associate Professor of the University of Tokyo in 1919. In 1922, he was promoted to a full professorship as the third Professor of Systematic Botany at the University of Tokyo after the departure of Matsumura. He was appointed director of the botanical garden in 1924. He retired in 1930, and he died in 1934 at the age of 59.[1]

Hayata described a total of over 1,600 different taxa, most of which are from Taiwan, but also include plants from Japan, China and Vietnam. From a list of Taiwanese plants currently recognized in the flora of Taiwan in 2003, 549 species, or 14% of Taiwan's flora, were described by Hayata. One example is the species Taiwania cryptomerioides, which Hayata himself saw the discovery of.

In 1920, the Imperial Academy of Japan awarded Hayata the Prince Katsura Commemoration Prize for his contribution to the flora of Formosa.[1]

Hayata's publications cover a period of more than 30 years, during which he authored more than 150 scientific articles and books.
