Commented phytosociological relevés from the Czech Republic 5

The fifth sequel of the series presenting remarkable phytosociological relevés brings new data on the distribution, ecology and species composition of six vegetation types fom the Czech Republic.

A rocky steppe dominated by submediterranean grass Stipa eriocaulis (Bromo-Festucion pallentis) recorded in southern Moravia is discussed in terms of its syntaxonomic position. Two thermophilous ruderal communities (Eragrostio minoris-Polygonetum arenastri, Eragrostio poaeoidis-Panicetum) are reported as new associations for eastern Bohemia. Tall herbaceous stands dominated by nitrophilous archaeophyte Parietaria officinalis (Urtico dioicae-Parietarietum officinalis) were documented at six sites in southern and eastern Moravia where only a few relevés had been recorded so far. Littoral vegetation with prevailing subhalophilous Schoenoplectus tabernaemontani (Schoenoplectetum tabernaemontani) was documented in southern Moravia where hardly any recent records are available. An isolated stand of calcicolous rock-outcrop lime forest (Seslerio caeruleae-Tilietum cordatae) was recorded in Czech Silesia for the first time.
