This book was reprinted many times in later years but the contents were not changed. Only the third of these publications cover the area within the present Polish borders. They are limited to the contemporary borders of Poland, but cover only several families of the choripetalous vascular plants. Thus none of the above works is adequate as a species checklist for the present territory of Poland. The nomenclature used in these works has also lost much of its currency.
Present checklist covers the whole of the vascular flora of Poland.
Not included were sporadic fugitives from cultivated areas. These would have extended too much the checklist and made it less clear. The array of plants grown in home gardens has fundamentally changed in recent years. The cultivated species included in the checklist are the authors' choice of the taxa which most often occur in Poland. In practice this means that in almost all cases of discrepancies with respect to the species or subspecies rank of a taxon we applied the species rank.
