Some New Records and Range Extensions of Arctic Plants for AlaskaJohnson, Albert W.; Viereck, Leslie A. (University of Alaska. Institute of Arctic Biology, 1962-09)Johnson, Albert W. and Leslie A. Viereck. 1962. Some new records and range extensions of arctic plants for Alaska. Biol. Pap. Univ. Alaska, No. 6. Pp. iv + 32. Many vascular plant species not previously reported from coastal northwest Alaska were found during floristic investigations in that region. Plant collections were made primarily in the Ogotoruk Creek-Cape Thompson area but extended as far as Keeseemalouk Creek on the southeast and to Cape Lewis on the northwest. This area is characterized by long, cold winters, cool summers, low precipitation, and high winds. Superimposed on substrates composed of basic to acidic rocks and their erosion products are vegetation types and plant communities, the most common of which are dominated by Dryas octopetala and sedges. The mosaic of habitats in the area includes broad wet meadows, dry fellfields, talus slopes, precipitous cliffs, gravel bars and benches, snow-beds, tundra ponds, strands, and coastal lagoons, each of which supports a characteristic aggregation of species. The 37 species presented in this paper are: Calamagrostis deschampsioides Trin., C. lapponica (Wahlenb.) Hartm., Trisetum sibiricum Rupr., Koeleria asiatica Domin., Puccinellia vaginata (Lge.)
