John Dransfield

British botanist.

John Dransfield (born 1945) is former head of palm research at the Royal Botanic Gardens, Kew, United Kingdom. Dransfield has written or contributed to several books on palms, notably both the first and second editions of Genera Palmarum. The first edition was the standard reference for palm evolution and classification and the second edition, expanding on the original, is expected to achieve that same benchmark. He studied at the University of Cambridge, B.A.(1967) biology, M.A. (1970) botany and Ph.D. biology (1970) before working at Kew Gardens. Dransfield was awarded the inaugural David F
