The supplementary botanical list features 64 species of vascular plants which are new, rare or forgotten records from the Faroe Islands. They are the cumulative notes produced from numerous excursions over the two last decades. The new species are described with notes of who discovered them, and literature references are given where appropriate. Some plants are not new discoveries for the Faroes but have been found in new localities or have been missed in most recent botanical lists. The plants are also categorized to relevant land management practice such as infield or outfield, altitude, and whether they show spreading potential, in the hope that this may guide future management and conservation of the rare and extinction prone species found in the Faroes. Fifteen non-native taxa in the list have been categorized as showing 'spreading potential' and may become invasive, e.g. Schedonorus arundinaceus, Alchemilla mollis, Epilobium komarovianum, Fuchsia magellanica, Reynoutria japonica and Mimulus/Erythranthe spp.
