Records of new species of vascular plants in Greenland from the last four decades arc presented and new phytogeographical data leading to extension of the known distribution limits in Greenland arc discussed. Since the publication of the latest edition of the Flora of Greenland in 1978 (Bocher et al. 1978) fieldwork by Greenland Botanical Survey and other expeditions have taken place especially in West and East Greenland and in many remote areas in North and Northeast Greenland. This paper serves as an update of the Flora of Greenland. Twenty species, one subspecies and one new forma have been added to the flora of Greenland: Carex membranacea Hook., Carex miliaris Michx., Carex rhomalea (Fernald) Mack., Equisetum hyemale L., Festuca edlundiae S. Aiken, Consaul and Lefkovich, Festuca groenlandica (Schol.) Frederiksen, Festuca saximontana Rydb., Galium verum L., Geum rossii (R. Br.) Ser., Papaver corn wallisense D. Love, Papaver dahlianum Nordh., Papaver lalnadoricum (Fedde) Solstad and Elven, Papaver lapponicum (Tolm.) Nordh., Pedicularis sudetica Willd. ssp. albolabiata Hult., Poa flexuosa Sm., Puccinellia bruszemanni Th. Ser., Ranunculus subrigidus W.B. Drew., vulgaris (Moench) Garcke, Trientalis europaea L. and Veron ica officinalis L. in addition to one subspecies Phippsia algida (Sol.) R. Br. ssp. algidifimnis (H. Sm.) Love and Love. The viviparous form of Poa hartzii f. prolifera has been reported for the first time in Greenland. Presently, the total number of vascular plant species in Greenland is 532. 89 new northern and 28 new southern distribution limits are presented and 26 species are new to the flora province East Greenland, whereas 15 species arc new to West Greenland. The numbers of new species to flora provinces North and South Greenland arc 14 and one, respectively.
