Note: The genus name was introduced by the French botanist Charles Louis L'Héritier de Brutelle (1746-1800) in Sertum Anglicum, seu Plantae rariores quæ in hortis juxta Londinum, imprimis in Horto Regio Kewensi excoluntur (London, 1788), p. 11. According to E.V. Slee et al., EUCLID: Eucalypts of Australia, 3rd edition (on-line publication), the specimen of Eucalyptus obliqua which L'Héritier described in Kew Gardens had been procured in 1777 by the botanical collector David Nelson at Adventure Bay, Bruny Island, Tasmania, on James Cook's third voyage to the Pacific.
