- Mown meadows with scattered trees were a characteristic of the old Swedish landscape. It has been an established truth that the botanists, particularly R. Sernander and H. Hesselman, did not understand that the meadows would turn into forests when abandoned, whereas the human geographer M. Sjöbeck in several publications from 1927 onwards made this clear. This view was supported by, i.a,. L.-G. Romell. We have scrutinized the literature and the minutes of the Plant Biology Seminar in Uppsala from 1892 to 1944, in order to understand Sernander’s views. Hesselman considered the matter uncertain. Sernander probably understood the dynamics also before 1927, but his standpoint was influenced by a wish to restore the postglacial broadleaved forests of which he saw the meadows as degraded relicts. This could be done by leaving meadows for free development. Gradually he saw the need also to maintain meadows and the cultural landscape as such. Several other botanists, e.g. G. Samuelsson and G. Einar Du Rietz, already early on understood the dependence of meadows on human management.

- Flora, vegetation and land-use history of Greenland are briefly described. The species-poor flora is Arctic. Thirteen endemic taxa may have survived the glacial period on Greenland.The latitudinal vegetation zones extend from High Arctic deserts to Low Arctic heaths with erect shrubs. A small area in the SW is Subarctic with elfin forests and meadows. A corresponding altitudinal zonation is also described.Greenland was colonised 1000 years ago by both Inuits and Norse settlers. The latter practised animal husbandry in the Subarctic SW. Hay-making was extensive on fertilized and irrigated fields. Extensive deforestation and land degradation took place, until the Norse population disappeared in the 15th century. It is argued that the decreasing population on Iceland during late medieval times made it possible for the Greenlandic Norse to move there. Modern sheep holdings have again caused land degradation. Notes on small-scale forest plantation and on ethnobotany are given.

- The late 19th and early 20th century was a time of intensive geological surveys, carried out in an atmosphere of national romanticism. This period has been described in a recent book by science historian Christer Nordlund, which is here presented and commentd on. Of special interest in Sweden was the issue of posglacial land upheaval and its consequencies for the development of the Baltic Sea. Special emphasis in the book is put on the importance of the geological results for plant geography and archaeology. The two botanists Gunnar Andersson and Rutger Sernander were active in this borderland between botany and geology. As scientists they represented very different mentalities and they soon became enemies. Andersson remained sceptical of the postglacial climate scheme developed by Blytt and Sernander, which he considered founded on too few data. A major scientific schism developed which culminated at the International Geological Congress in Stockholm in 1910. Nordlund is probably right in his view that the interdisciplinary work in the late 19th century relating to historical plant geography and geological development had an impoartant impact on early ecology and its formation as a science.
