The historical investigation of the palaeobotany of the Azores Islands led to the recent rediscovery of the leaf fos sils initially collected by Arruda Furtado in the late 19th century. Advised by Sir Charles Darwin and Sir Joseph Dalton Hooker to search for plant fossils, Arruda Furtado found the first specimens in São Miguel Island, and sent them to the UK for further identification. A recent search at the Natural History Museum, UK, revealed that from a total of sixteen specimens, only one specimen survived. In the same tray, two undescribed specimens from Furnas (São Miguel) were found. Here we describe and identify them as Woodwardia radicans, Laurus azorica and an unidentified fern. The taphonomy indicates that these fossils were preserved in a trachytic tuff, possibly related to the explosive episodes of the Furnas volcano, indicating that they could be late Pleistocene to Holocene in age. This report aims to highlight the potential of future palaeobotanical studies of the Azores Islands.
