Sokoloff Sokoloff Sokoloff Humphrey s Saarela Humphrey s Despite two centuries of botanical exploration in the Canadian Arctic Archipelago (CAA), there are substantial gaps in our understanding of vascular plant species distributions in this large and difficult-to- access region. Many areas have not been explored by botanists and documented with specimens. Knowledge of species distributions represents important baseline data that may be useful for understanding how arctic species and the ecosystems in which they live may respond to climate change. Monocots are represented in the Canadian Arctic Archipelago by six families and 105 species, according to the most recent floristic account of the region (Aiken et al. 2007): • Poaceae – 46 species: Agrostis (1), Alopecurus (1), Anthoxanthum (2), Arctagrostis (1), Arctophila (1) Calamagrostis (4), Deschampsia (3), Elymus (1), Festuca (7), Hordeum (1, introduced), Leymus (1), Lolium (1, introduced), Phippsia (2), Pleuropogon (1), Poa (6), Puccinellia (11, including P. banksiensis Consaul, 2008), ×Pucciphippsia (1), Trisetum (1) • Cyperaceae – 45 species: Carex (33), Eleocharis (1), Eriophorum (7), Kobresia (3), Trichophorum (1) • Juncaceae – 10 species: Juncus (5), Luzula (5) • Potamogetonaceae – 1 species: Stuckenia (1) • Orchidaceae – 1 species: Corallorhiza (1) • Tofieldiaceae – 2 species: Tofieldia (2) In July 2012 we conducted a botanical inventory in Katannilik Territorial Park along the Soper River on southern Baffin Island, Nunavut, a region in which plant diversity is rich but has been poorly documented. Among our ca. 900 collections are first records of monocots for Baffin Island and the CAA, representing major range extensions for these species, and collections that expand our knowledge of the Arctic distributions of monocot taxa that are rare and/or poorly known in the CAA, previously documented by one or a few collections. Most of the monocot species discussed here reach their northeastern limit in Canada on southern Baffin Island. Voucher specimens are housed in the National Herbarium of Canada (CAN) at the Canadian Museum of Nature. Previously known only from Iqaluit in the CAA, where it was accidentally introduced in the 1980s (Aiken et al. 2007), we found three robust plants of this species in the community of Kimmirut: two near the garbage dump, one in town. It is the only naturally introduced plant species (i.e., not planted) known in the CAA. This species has been seeded in Arctic communities for stabilizing soil and as a potential lawn grass (Aiken et al. 2007). It is common and robust in the community of Kimmirut around buildings and along roads, but we did not find the species in natural habitats in the area. It has not previously been reported from Kimmirut. It should be looked for in other Arctic communities. Discovery of this widely-distributed temperate species growing in wet, brackish habitats at two sites on southern Baffin Island adds a new monocot family, Juncaginaceae, to the flora of the CAA. Its presence is not particularly surprising as it is known from several Arctic sites in adjacent northern Quebec (Blondeau and Cayouette 2002). It is also known from a few sites on mainland Nunavut and the Northwest Territories (Blondeau and Cayouette 2002; Saarela et al. 2013). Sokoloff This circumboreal species was found at three mesic sites; it was rare at two sites (only a few plants to scattered plants), and locally common at one site. It is moderately common in adjacent Quebec-Labrador north of 54°N, where it extends into the arctic zone (Cayouette 2008). Its discovery on Baffin Island increases the number of Carex species known from the CAA to 34. An amphi-Atlantic species now known from 9 sites in the CAA. A circumpolar-alpine species now known from 11 sites in the CAA, including one on southern Victoria Island (Saarela & Gillespie, unpublished data). A primarily boreal species of shores, wetlands and mud boils that extends into the arctic zone, now known from 4 sites in the eastern CAA. A scattered subarctic-cordilleran species of shores and wetlands, now known from 10 sites in the CAA, including 3 new sites on southern This species has not previously been collected in the CAA. Its distribution is primarily boreal, extending into the Low Arctic on the mainland. It has been collected at Wakeham Bay in adjacent northern Quebec (records not on map above; Blondeau and Cayouette 2002). We found three populations: one (Saarela et al. 2197) had two sub-populations, one with 24 plants, one with 56 plants; the second (2209) had over 100 plants in a 10m 2 area; and the third (2488) had over 250 plants in a 20m x 2m area. This is the second orchid genus and species known from the CAA. Aiken et al. 2007 Bu ll Bu ll Corallorhiza trifida Châtel. Saarela et al. 1970, 2036, 2415 A diminutive, primarily Low Arctic species of sedge meadows and moist tundra, now known from 8 sites in the CAA, most on southern Baffin Island. A circumboreal-polar species, common in the western CAA, previously known from only a single site on Baffin Island; now known from six additional sites there. A circumpolar taxon now known from eight sites in the CAA, all but one on southeastern Baffin Island. A circumpolar-alpine species, now known from nine sites in the CAA, 8 on Baffin Island and one on southern Victoria Island (Saarela & Gillespie, unpublished data). A distinctive rush with an arctic-alpine amphi-Atlantic distribution, now known from six collections in the CAA, all on southern Baffin Island. An arctic-alpine species, generally common in the CAA, but not previously reported from southern Baffin Island, where we made four collections of the species. A circumboreal species known previously from two collections on Baffin Island. It is fairly common along the Soper River, where it grows in mesic places, often forming large, distinctive patches. It is also the dominant understory species in a large willow "forest" (Salix planifolia) in the Soper River valley. It is not known from elsewhere in the CAA. This circumpolar species, known from numerous arctic sites on the mainland, was previously known in the CAA from two sites in Auyuittuq National Park, Baffin Island. We found three new populations in turfy, open areas (river flats) along the Soper River. At one site we counted 19 plants (ramets) in a 5m x 2m patch, and 15plants (ramets) at another site. We also collected this species on southern Victoria Island in 2008 (Saarela & Gillespie, unpublished data). Saarela Saare la Saarel a Saarel a Bu ll Sokoloff
