Abstract
THE scientific communications published in this volume are mainly of local interest. Prof. Ed. Fischer chronicles additions to the list of species in the flora of Berne which have been noted in the past ten years; a large number are aliens which have been introduced in various ways. The most important communication in point of length is by Werner Lüdi on “The Succession of Plant Associations,” an ecological study of the vegetation of the Bernese Oberland, with special reference to the Lauterbrunnen valley. Dr. R. Stager describes some myrmecological observations on the Belalp at more than 2000 metres elevation, in which he notes the distribution of the seeds of Thesium alpinum by two species of ant. E. Gäumann gives an account of the occurrence and area of distribution in Switzerland of the species of the parasitic fungus genus Peronospora, arid there is also a paper on the etiology of the “grippe” by Dr. Sahli.
