In the summer of 1966 three students, bachelors in botany, of the State University of Utrecht, Netherlands, made botanical investigations in the Angmagssalik area (65°°20' N. lat.) in South-east Greenland. The main purpose was to carry out floristical and ecological investigations, while special attention was paid to the altitudinal belts in the vegetation on mountain slopes. The fieldwork will be continued in 1968. From the botanical collection the lichens were identified by the author and are listed here, except some critical species of which the determinations have not been finished yet. The number of samples collected amounts to ca. 300, most of them taken from vegetation analyses. All samples will be incorporated in the Herbarium of the State University of Utrecht, Netherlands.
