Recent studies have shown that Acacia is polyphyletic and must be split into five genera. Proposal 1584 would retypify Acacia : the type of the Australian taxon A. penninervis would be conserved over the current lectotype (A. scorpioides ) of an African taxon. We disagree with the recommendation of the Spermatophyte Committee to endorse this proposal. Contrary to Article 14.12 of the ICBN, no detailed case against conservation was presented in Proposal 1584. We maintain that there are strong arguments against conservation, such as the large number of countries that would be affected, the economic importance of the extra‐Australian species, and the economic burden placed on developing countries. Acceptance of this proposal would also violate the guidelines for conservation which clearly state that the principle of priority should prevail when conservation for one part of the world would create disadvantageous change in another part of the world.

Joseph Dalton Hooker (1817–1911) was 22 years old when he undertook his first natural history journey abroad. He was appointed ‘Assistant Surgeon’, under the command of James Clark Ross in the Antarctic Expedition 1838–1845, also known as the South Pole Magnetic Expedition. The two HMS ships The Terror and The Erebus made brief stops in the Macaronesian islands of Madeira, Tenerife (the Canaries), and Santiago (Cabo Verde) where Hooker took the opportunity to observe and collect animals, plants and minerals, so these were the first three collecting sites documented in his Antarctic Journal.
