From 6 April 1842 a long stay in the Falklands began, where the flora was investigated to supplement the work of the French explorer Admiral Jules Dumont d'Urville, who had sailed to the Antarctic and the Pacific between 1837 and 1840, and of the crew of the Uranie, who had visited the South Atlantic and the South Pacific between 1817 and 1820. In the Flora Atlantica, Hooker praises the work of the English botanist Sir Joseph Banks and his Swedish assistant, Daniel Solander, on Captain Cook's first voyage in 1769. Hooker also mentions Cook's second voyage and the explorations of the French survey ship Coquille, on which D'Urville had served as a young officer. When visiting the Hermite Islands, seedlings of the deciduous Nothofagus antarctica and the evergreen Nothofagus betuloides were collected from this southernmost location of any tree. These were planted on the Falklands, and some were later brought to Kew. On Cockburn's Island twenty cryptogam species were found. The ships returned to the Cape of Good Hope on 4 April 1843. At the end of the journey specimens of some fifteen hundred plant species had been collected and preserved.
