ADDITIONS TO VASCULAR PLANT FLORA OF THE WESTERN SUWAŁKI LAKELAND, NORTH-EASTERN POLAND

The present study provides a floristic list of twenty vascular plant species recorded in 2015–2016 in the Western Suwałki Lakeland, north-eastern Poland, by using the ATPOL cartogram method. Attention is drawn to the species Camelina sativa, Geranium columbinum, Rubus corylifolius aggr., Salix ×mollissima and Vicia pannonica, which are new to the regional flora. Through this study, the distribution status of Allium vineale and Erigeron acris subsp. serotinus in the region has changed from the category of very rare taxon to the category of rare taxon. Two newly recorded species, Camelina sativa and Vicia pannonica, may become established in the Western Suwałki Lakeland in the future as agricultural weeds.
