of the non-differentiating species is presented in alphabetical order. Species presence is indicated
as relative frequency; i.e. number of releves in the plant community in which the species is found.
The lists of both differential and non-differential species include taxonomic entities which are in
fact clusters of species. These clusters are indicated by the suffix 'group' (gr).
