This paper deals with the results of a microscopical analysis of the lignites of the miocene browncoal from the quarry “Anna” in the south of Limburg (Netherlands). They appeared to consist of 14 wood species, distributed over Conifers (6). Monocotyledons (1) and Dicotyledons (7). Four dicotyledonous woods were found fot the first time and described here. Some conclusions about vegetation and climate are added.
