The article contains results of geobotanical studies carried out in 2003—2004 and supplemented in the summer of 2009, in the area of a local railway line in the Wielkopolska region in Poland, between the railway stations of Czempiń and Śrem, on the total line length about 20 km. The studies include vascular plants spontaneously occurring within the area. In order to reveal the characteristic features of the flora, the studied railway line was divided into 37 equal segments and each segment was regarded as a separate locality. For each registered species, the total number of localities provided the basis for the determination of the occurrence frequency by a 5-degree scale. The flora of the studied railway line includes 332 plant species. Among them, indigenous species (apophytes) distinctly dominate as compared to anthropophytes, while, in terms of species numbers, the richest groups are families Asteraceae and Poaceae. The most frequently encountered species were Artemisia vulgaris and Hy peri cum perforatum, found in all localities on the railway line. Our studies also have demonstrated that, despite the local character of the studied railway line, the identified flora also includes plants revealing a particular preference for occurrin along main railway lines. Among others, they include Aegilops cylindrica, Bromus japonicus, Bunias orientalis, and Lepidium virginicum. A comparison of the major part of the flora from six localities on the railway line between the first station Czempiń and the last station Śrem has shown the highest similarity. Its value calculated with the use of the Steinhaus equation (similarity coefficient, similarity indices) showed 0.74.
