De plantengemeenschappen van de Wassenaarse duinen = (The plant communities of the Wassenaar dunes near The Hague)
The plant communities on about 1800 ha of dunes were studied before any consequences could be observed of percolation since 1955 of fresh water stored underground for mains supply. Classification was by the French-Swiss and sometimes the Scandinavian sociological system. Some difficulties of classification by the French-Swiss method were discussed. The floristic composition, distribution of the communities and their mutual relations were considered. Chapters cover the broad plant formations, arranged according to succession. New sub-alliances introduced were Erodio-Koelerion albescentis (slightly open dune vegetation on usually limy substrate) and Luzulo-Koelerion albescentis (closed dune grasslands, later in the succession; topsoil often leached of lime).New associations described were Erodium glutinosum-Phleum arenarium- assn. (dune district as far as N. France), Jasione montana var. Litoralis-Phleum arenarium- assn. ( Netherlands and German Friesian Isles), Didymodon recurvirostris - Tortella flavovirens -assn. (small associations mainly of cryptogams on northern faces of limy banks), Ranunculus bulbosus - Trifolium striatum -assn. (moderately grazed or ruderally influenced; completely leached soil; old dunes), (sub-assn. Koeleria albescens on grounds used for drying fishing nets), Hippophaë rhamnoides-Sambucus nigra -assn. and Crataegus monogyna-Betula pubescens -assn.
