The paper presents plant communities from northern Wedel Jarlsberg Land. 55 species of vascular plants were described in this region. Differentiation of plant communities is discussed as controlled by habitat conditions. Plant succession in intramorainal zones of Renardbreen and Scottbreen has been also considered.
Botanic investigations were carried through on the Calypsostranda strandflat, southern coast of Bellsund. Among flora communities 35 moss species were distinguished. Connections between moss habitats and ecologic conditions were studied.
