New vascular plant records for the Canadian Arctic Archipelago.


ABSTRACT: The Canadian Arctic Archipelago is a vast region of approximately 1,420,000 km(2), with a flora characterized by low species diversity, low endemicity, and little influence by alien species. New records of vascular plant species are documented here based on recent fieldwork on Victoria and Baffin Islands; additional records based on recent literature sources are mentioned. This paper serves as an update to the 2007 publication Flora of the Canadian Arctic Archipelago, and brings the total number of vascular plants for the region to 375 species and infraspecific taxa, an increase of 7.7%. Three families (Amaranthaceae, Juncaginaceae, Pteridaceae) and seven genera (Cherleria L., Cryptogramma R. Br., Platanthera Rich., Sabulina Rchb., Suaeda Forssk. ex J.F. Gmel., Triglochin L., Utricularia L.) are added to the flora, and one genus is deleted (Minuartia L.). Five species are first records for Nunavut (Arenarialongipedunculata Hultén, Cryptogrammastelleri (S.G. Gmel.) Prantl, Puccinelliabanksiensis Consaul, Saxifragaeschscholtzii Sternb., Utriculariaochroleuca R.W. Hartm.).
