Important findings of 49 species of vascular plants, mosses, liverworts, lichens and aphyllophoroid fungi acquired lately from the utter North-West of Russia are reported. The findings were considered important if they were newly detected for the Murmansk Region, red-listed in Russia and/or Murmansk Region, new for the Pasvik Strict Nature Reserve, other particularly rare species known from not more than five locations in the Murmansk Region. The native Sesleria uliginosa Opiz and five adventitious species (Avenula pratensis (L.) Dumort., Capsicum annuum L., Coriandrum sativum L., Carex contigua Hoppe and Phaseoius vulgaris L.) are reported for the Murmansk Region for the first time. The species detected in the Pasvik Reserve for the first time are vascular plants Carex acuta L., Carex tenuiflora Wahlenb., Eleocharis palustris (L.) Roem. et Schult., Lemna trisulca L., Ranunculus pygmaeus Wahlenb., Viola epipsiloides À. Löve et D. Löve and bryophytes Buxbaumia aphylla Hedw., Mesoptychia badensis (Gottsche ex Rabenh.) L. Söderstr. et Vâna and Nardia breidleri (Limpr.) Lindb. New data are reported about the nationally and regionally red-listed species Isoëtes echinospora Durieu, Bryoria fremontii (Tuck.) Brodo et D. Hawksw. and Nardia breidleri (Limpr.) Lindb., and about 21 more species listed in the Red Data Book of the Murmansk Region. The new records for six species of aphyllophoroid fungi (Amylocorticium cebennense (Bourdot) Pouzar, Craterellus lutescens (Fr.) Fr., Flaviporus citrinellus (Niemelä et Ryvarden) Ginns, Henningsomyces candidus (Pers.) Kuntze, Hydnum umbilicatum Peck, Peniophora pini (Schleich.) Boidin) and the lichen Stereocaulon capitellatum H. Magn. represent the second locations detected in the Murmansk Region.
