The Canadian Arctic Archipelago is a vast region of approximately 1,420,000 km2, 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 (Arenaria longipedunculata Hultén, Cryptogramma stelleri (S.G. Gmel.) Prantl, Puccinellia banksiensis Consaul, Saxifraga eschscholtzii Sternb., Utricularia ochroleuca R.W. Hartm.)

The Canadian Arctic Archipelago (CAA) is a group of islands occupying the northern third of Canada extending about 3000 km south to north and east to west, and covering approximately 1.42 million square kilometers. The archipelago comprises three very large islands, Baffin (507,451 km2), Victoria (217,291 km2), Ellesmere (196,236 km2), twelve islands between 10,000 and 71,000 km2, and many thousands of smaller islands (Fig.
Study of the Canadian Arctic Archipelago flora started with expeditions searching for a northwest passage in the early 1800s, such as the Parry Expedition (see
Recent fieldwork by our team on Victoria Island in 2008 and 2010, and on Baffin Island in 2012, led to discoveries of species new to the CAA and many significant range extensions. Here we document our major findings, including species, genera and families new to the CAA and species new to the western and eastern parts of the Arctic Islands. A subset of these are first records of species for Nunavut. We also summarize the literature pertinent to the CAA flora published since 2007 (or that was not included in
Fieldwork in the CAA was carried out in 2008, 2010 and 2012. In July 2008 and 2010, we collected vascular plants on southern Victoria Island, Nunavut, and on north western Victoria Island, Northwest Territories (Fig.
The new discoveries described here plus new species and significant distribution records published recently bring the total number of vascular plant taxa in the CAA to 42 families, 141 genera and 375 species and infraspecific taxa (368 species). Table

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. One genus (Minuartia L.) is deleted from the flora. We document six recently described taxa as additions to
Several taxa are added to the flora of the CAA as a result of recent taxonomic revisions. Chrysosplenium rosendahlii Packer, described from Somerset Island (
Several older publications and collections from the Arctic Islands have come to light since the publication of
The majority of the new records described here are assumed to be discoveries of long established species that have simply been overlooked by botanists. One record, Hordeum jubatum L., an introduced weedy species found within the Kimmirut town site, is obviously a recent introduction. Documenting the present day flora is essential as baseline data for future studies of floristic changes resulting from the warming climate or from anthropogenic introductions due to increased human traffic.
Steller’s rockbrake
Disjunct circumboreal (absent from Greenland and Europe)
This is the first record of the species, genus and family from the CAA and for Nunavut. The genus is easily distinguished from other fern genera in the Arctic Islands by its dimorphic fronds. We discovered one small population on a southeast facing cliff by Fundo Lake on the outskirts of Kimmirut. Plants were small with sterile fronds 3–5(7) cm long and fertile fronds 4–8 cm long, and were growing with moss in horizontal fractures in grey marble.
Uncommon and with a scattered and disjunct distribution, C. stelleri is found in North America primarily in the western montane boreal and eastern boreal zones (

Brownish sedge
Circumboreal-polar
This is the first report of the species from the CAA. Our collections were gathered in Katannilik Territorial Park on southern Baffin Island, where the cespitose species was found at three sites in damp, turfy places. It was rare at two sites (only a few scattered plants), and locally common at one site. Associated species include Betula glandulosa Michx., Calamagrostis canadensis var. langsdorffii (Link) Inman, Chamerion angustifolium (L.) Holub, Carex arctogena Harry Sm., C. bigelowii Torr. ex Schwein., Pedicularis lapponica L., Poa arctica R. Br. and Taraxacum ceratophorum (Ledeb.) DC.
This boreal species extends to the treeline across Canada, and into the Arctic zone in northern Quebec and northern Labrador, where it is moderately common (

Marsh arrowgrass
Circumboreal-polar
Discovery of this widely-distributed temperate and facultatively halophytic 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. This taxon is diminutive on Baffin Island, ranging from 6–12 cm tall (larger elsewhere in its range, up to 42.5 cm tall;
One collection was gathered from a population in wet sandy ground in a dried up depression adjacent to meromictic Soper Lake, associated with Eriophorum scheuchzeri Hoppe, Juncus arcticus Willd., Carex bicolor, and Dupontia fisheri R. Br. The second collection was gathered from a sedge meadow at the input of Fundo Lake, associated with Carex atrofusca Schkuhr, C. gynocrates Wormsk. ex Drejer, C. membranacea Hook., C. microglochin, C. rariflora (Wahlenb.)

Northern coralroot, early coralroot
Circumboreal-polar
Our collections represent the first record of the species in the western CAA, and the second for the eastern CAA and Baffin Island. Thought to be the only orchid in the CAA (
In the Soper River valley on southern Baffin Island we found the species to be scattered, but never common, on densely vegetated river flats, riverbanks, and peaty wet meadows at several localities. Our three collections increase the number of records for Baffin Island to four. In adjacent northern Quebec, the species occurs along the coast and in the interior, known from only three Arctic localities (
The species is a near-complete mycoheterotroph (

Northern bog orchid
Boreal North America
This is the first record for this genus and species, and the second species of orchid discovered (see Corallorhiza trifida), in the CAA (
Along the Soper River on southern Baffin Island we collected three populations. The first (Saarela et al. 2197) had two subpopulations with a total of 80 plants, the second (Saarela et al. 2209) came from a population of over 100 plants in a 10 m2 area, and the third (Saarela et al. 2488) was from a population of over 250 plants in a 80 m2 area. Near the third population was an even larger population estimated at over 1000 plants that was not collected. These populations were found in moist sedge-willow hummocks set on small hills and valleys on the lower slopes of the Soper Valley away from the banks of the Soper River, growing in association with Betula glandulosa, Salix arctophila Cockerell ex A. Heller, S. calcicola Fernald & Wiegand, S. reticulata, Empetrum nigrum L., Rhododendron lapponicum (L.) Wahlenb., Equisetum arvense L., Cassiope tetragona (L.) D. Don, Vaccinium uliginosum L., and V. vitis-idaea L. While the first two populations were encountered within a few kilometers of each other, we encountered the third, largest population 20 kilometers away, suggesting that other populations may occur in the area where habitat is suitable.

Foxtail barley
North America–NE Asia
Hordeum jubatum is a widely distributed species that grows in meadows, along rivers, around lakes, and in disturbed habitats such as roadsides (
Although the species is distributed primarily in temperate and sub-Arctic regions of North America there are sporadic collections of both subspecies from Arctic regions of Alaska (
Hordeum jubatum was apparently accidentally introduced as early as the 1960s to Apex (near Iqaluit, Baffin Island, CAA) with straw used as animal feed and/or packing material (
We found three robust plants of H. jubatum subsp. jubatum in the community of Kimmirut in 2012, adding a second area of occurrence for the species on Baffin Island. Two plants were growing in a lush sewage runoff area near the garbage dump on slopes well above the coastal high tide line with Chamerion latifolium (L.) Holub, Poa alpina L., P. glauca Vahl, Salix glauca L., Stellaria longipes Goldie and Taraxacum lapponicum Kihlm. ex Hand.-Mazz., and one in the hamlet, growing on a rocky, sandy beach adjacent to the coast associated with Poa arctica and Taraxacum lapponicum (Fig.

Creeping sandwort
Arctic North America–amphi-Atlantic
Our collections from the Minto Inlet area of Victoria Island represent the first record of the species from the western CAA. Plants were matted, often large, forming loose circular cushions and were found growing on inland sand dunes. Although the species is primarily distributed in the eastern Canadian Arctic and sub-Arctic (south to Nova Scotia) and around Hudson Bay, it is also found scattered on the Northwest Territories and Nunavut mainland south of Victoria Island (specimens at CAN).

Long-stemmed sandwort
Arctic-alpine amphi-Beringia–North America
Our collections are the first records of the species for the CAA and Nunavut. Described by
The ranges of A. longipedunculata and A. humifusa overlap in the Arctic Islands; indeed we collected both species in the Soper River-Kimmirut area on Baffin Island, and both on Victoria Island but in different localities. In northern Quebec and Newfoundland some large specimens identified as A. humifusa appear to approach A. longipedunculata in some characters; these robust matted plants have elongate stems with long internodes and pedicels. Further study of this species complex is needed to determine more precisely species boundaries and distributions and to determine if hybrid or introgressed populations exist in the Canadian Arctic.

Eschscholtz’s saxifrage
Amphi-Beringia
Comments: Collected on Bathurst Island by S. Edlund in 1975, this is only the second collection of this species from the CAA, and the first record from Nunavut. Edlund’s collection was shelved in the backlog of the National Herbarium of Canada for nearly 40 years, and was only recently uncovered. However, its significance as a new record was noted on the newsprint accompanying the specimen, indicating its importance was apparent to the collector.
