Abstract:
Based on herbarium studies, eight charophytes are reported from Greenland: Nitella flexilis, N. opaca, Tolypella canadensis, T. nidifica f. groenlandica nov. form., Chara canescens, C. contraria, C. globularis, C. globularis f. bulbillifera nov. form. and C. delicatula. In addition Chara baltica has been reported in the literature. The total number of known species is therefore nine. Of these 9 species five are commen in Europe and North America; one (C. canescens) has its main distribution in Europe with a few finds in Northeast America; another (T. canadensis) has a northern amphi-atlantic distribution; a third (C. baltica) has its main distribution in Europe and is found in a few localities in South America. One species (T. nidifica) has a European distribution only. The early immigration of charophytes to Greenland and the development of early bird migration routes in this direction lead us to believe that the charophyte flora of Greenland has moe affinity to Europe than to North America. Some ecological factors are discussed below for each of the species
