Vahlodea
Vahlodea is a monotypic genus of plants in the grass family. The only known species is Vahlodea atropurpurea Its native range is the subarctic (such as Greenland), to temperate parts of the Northern Hemisphere. From (Europe within; Finland, North European Russia, Norway and Sweden,) to Asia within (Japan, Kamchatka, Kuril Islands, Magadan and Taiwan,) and in North America (within the Canadian provinces of; Alberta, British Columbia, Manitoba, Newfoundland and Labrador, Northwest Territories, Nunavut, Ontario, Québec and Yukon and within the USA states of; Alaska, the Aleutian Islands, California, Colorado, Idaho, Maine, Montana, New Hampshire, New York, Oregon, Vermont, Washington  and Wyoming,) and also southern South America (within Argentina and Chile). The genus name of "Vahlodea" is in honour of Jens Vahl (1796–1854), a Danish botanist and pharmacist. The Latin specific epithet of "atropurpurea" means "dark-purple coloured". Both the genus and the sole species were first described and published in Bot. Not. (1842) Vol.141 on page 178 in 1842. The genus is recognized by the United States Department of Agriculture and the Agricultural Research Service, and they list "Vahlodea atropurpurea" as the known species. It was thought to be a synonym of "Deschampsia" , but Chiapella, J. 2007. A molecular  phylogenetic study of "Deschampsia" (Poaceae: Aveneae) inferred from nuclear ITS and plastid trnL sequence data: support for the recognition of "Avenella" and "Vahlodea". Taxon 56:55-64.
