The first collector of marine algae in Greenland waters seems to have been J.M.Vahl who lived in Greenland from 1828 to 1836. Vahl's East Greenland species were not recorded until 1893 when Rosenvinge included them in his work of 1893 together with the species collected by Sylow (Lund, 1959).[16] F.R.Kjellman records only 12 species from East Greenland 4 of which are doubtful, these records are based on Zeller's list (Lund, 1959).[16]
