Notes on the syntaxonomy of the Asplenietea trichomanis class in Poland

A revised syntaxonomy of rocky and wall plant communities occurring and likely to be found in Poland is presented in the paper. Currently eleven associations and three communities are known from the whole area of the country, and four further associations probably occur here. A revised division of the class Asplenietea trichomanis (Br.-Bl. in Meier & Br.-Bl. 1934) Oberd. 1977 into three orders with six alliances is also given.
