Paul M. Catling

Abstract


Eleven species are reported as new to the flora of the continental Northwest Territories. The new native species include Artemesia dracunculus, Chenopodium leptophyllum, Eleocharis erythropoda, Panicum capillare, Schoenoplectus pungens and Symphyotrichum lanceolatum subsp. hesperium var. hesperium. New alien species reported include Achillea ptarmica, Chaenorhinum minus, Galium aparine, Malva neglecta and Silene cserei. Sonchus arvensis, previously reported, is based on material referable to a subsp. uliginosus. Forms new to the flora include Achillea millefolium f. rosea and Actaea rubra f. neglecta. Locations, habitats and distinctive features are provided for the additional taxa. The Hay River lowland ecoregion is a floristically rich area that deserves more botanical exploration.
