Dutch botanist (1922-1994).
Ruurd Dirk Hoogland (1922 Leeuwarden - 18 November 1994 Paris) was a Dutch-born explorer and naturalist, who migrated to Australia and made numerous botanical expeditions to New Guinea, Oceania and Europe. He was an expert on the family Cunoniaceae. He received his university education in Groningen and Leiden. He earned his doctorate in 1952 with a review of the genus Dillenia under Professor van Steenis and in that year he joined the Australian CSIRO in the Division of Land Research in Canberra as a botanist initially focusing on the then Australian "dependency" of Papua New Guinea.
