4689. LINDSTRÖM, A. Marstrandsöns Ormbukar och Fanerogamer. [The ferns and phanerogams of the Island of Marstrand.) Bot. Notiser 1920: 177-210. 1920.—The island is very rocky and the shores very barren. A meager flora might be expected, especially as part of the island is occupied by the town and the old fortress. After 14 years of study by the author and partly by Nordstedt, a list of 13 fern worts and more than 600 species, varieties, and hybrids of phanerogams is published. Among these there are described 2 subspecies, 3 varieties, 1 hybrid and 19 species of Rosa. As the author has a very peculiar system in this gen'is, it is scarcely possible to tell whether these should be regarded as species or subspecies, he using binomials for both categories and calling both "sp. nov.” As an appendix are added lists, without notes, of the plants found on neighbouring small islands: Hamneskär 33, Gråen 91, Östra Kråkan 76, Vestra Kråkan 52, and Kråkan at Rösselvik 56 species and varieties.P.
