On the 19 th Aug. a visit to the N side of Nathorst Land in Van Mijenfjorden was planned, but the wind made landing impossible. Instead, the expedition visited Svarthamaren on the E side of Recherchefjorden on Wedel Jarlsberg Land (77°32’N, 14°15’E). The bryophyte flora of this site is rather typical for some sites in inner fjord areas of Svalbard. Several species that are widespread in Svalbard are rather abundant but also some species that were regarded as rare in Svalbard occur sporadically here .

The wind made landing difficult also next day, but the expedition was able to visit Strandvollsletta below Bravaisberget on the S side of Nathorst Land (77°37’N, 14°55’E). This is a rich site where we found many species, both common and widespread ones and more rare species.

A fair part, but not all, of the collected specimens from this expedition is identified. However, among the identified, there are many new species records for the visited areas, increasing the knowledge of their distribution on Svalbard.

In spite of all those expeditions, only one species, Lophozia svalbardensis , has been described from Svalbard during the last 20 years (Konstantinova et al., 2020a).
