Leslie Pedley

From Wikipedia, the free encyclopedia

Leslie Pedley (19 May 1930 – 27 November 2018)[1][2] was an Australian botanist who specialised in the genus Acacia. He is notable for bringing into use the generic name Racosperma, creating a split in the genus, which required some 900 Australian species to be renamed, because the type species of Acacia, Acacia nilotica, now Vachellia nilotica, had a different lineage from the Australian wattles.[3] However, the International Botanical Congress (IBC), held in Melbourne in 2011, ratified its earlier decision to retain the name Acacia for the Australian species, but to rename the African species.[4]

See also: Acacia and Vachellia nilotica regarding the dispute, and APNI for a brief history of the name, Racosperma.[5]

In 2018, Japanese botanists Hiroyoshi Ohashi and Kazuaki K. Ohashi published Pedleya H.Ohashi & K.Ohashi (in the Fabaceae family) from New South Wales, the name "honors Mr. Les (Leslie) Pedley of Queensland Herbarium, Brisbane Botanic Gardens Mt Coot-tha, who revised Desmodieae of Sri Lanka and Australia".[6]
