Abstract

Japanese grass-herb-communities on sea cliffs were syntaxonomically studied. The floristic comparison of these communities indicates that there are two vegetation classes. One vegetation class, the Crepidiastro-Dendrsthemetea, is distributed in southern Japan, and characterized by the genus Crepidiastrum (Asteraceae) and Dendranthema (Chrysanthemum s. l.). The other class, Plantagini camtschaticae-Festucetea, is distributed in northern Japan. The Crepidiastro-Dendrathemetea are one of the endemic vegetation classes in humid subtropic E-Asia. The Plantagini-Festucetea have some ecological and symmorphological features common with the European Sedo-Scleranthetea. Syntaxonomic hierarchies of these two new classes are as follows: Crepidiastro-Dendrathemetea Ohba et Saguwara 1977, Crepidiastro-Dendrathemetea ordo nova, Peucedanion japonicae Ohba 1971 (10 associations); Miscanthetalia condensati v. boninensis ordo nova, Miscanthion condensati v. boninensis all. nova (1 association); Plantagini camtschaticae-Festucetea classis nova, Artemisietalia littoricolae ordo nova, Artemision littoricolae all nova (6 associations); Nipponanthemetalia nipponicae ordo nova, Nipponanthemion nipponicae all. nova (1 association).

Kurzfassung

Die japanischen Gras-Fluren an den Kliff-Küsten werden syntaxonomisch studiert. In Süd-Japan charakterisieren die Gattung Dendranthema (Chrysanthemum s. l.) und Crepidiastrum (Asteraceae) diese Grasfluren. Die Klasse Crepidiastro-Dendranthemetea ist dem subtropischen humiden Ostasien eigentümlich. In Nord-Japan können wir eine zweite Klasse, die Plantagini camtschaticae-Festucetea, unterscheiden. Die Systematik der beiden Klassen ist die folgende: Crepidiastro-Dendrathemetea Ohba et Saguwara 1977, Crepidiastro-Dendrathemetea ordo nova, Peucedanion japonicae Ohba 1971 (10 Assoziationen); Miscanthetalia condensati v. boninensis ordo nova, Miscanthion condensati v. boninensis all. nova (1 Assoziation); Plantagini camtschaticae-Festucetea classis nova, Artemisietalia littoricolae ordo nova, Artemision littoricolae all nova (6 Assoziationen); Nipponanthemetalia nipponicae ordo nova, Nipponanthemion nipponicae all. nova (1 Assoziation).
