A New Combination in Deschampsia (Poaceae) in Arctic North America 1

Northern North American populations of Deschampsia P. Beauv.

Description
Summary:Northern North American populations of Deschampsia P. Beauv. (Poaceae) present many taxonomic and nomenclatural problems resulting from: 1) morphologic clinal variation across the continent; and 2) overlap in taxonomic use of specific and/or infraspecific epithets that are also used in European or Russian plants. The new name D. cespitosa (L.) P. Beauv. subsp. septentrionalis Chiapella replaces the illegitimate combination D. cespitosa subsp. brevifolia (R. Br.) Tzvelev [[ D. brevifolia R. Br.].
