Het Festuca ovina-complex in Nederland. 4. Festuca csikhegyensis Simonk. op het Harskampse Zand

During the inventory of the military firing range east of the village of Harskamp on the Veluwe, Province of Gelderland, in 2003, Festuca csikhegyensis Simonk. was discovered. This species includes the tetraploid populations formerly included in F. pallens Host. In this paper, F. csikhegyensis is briefly described. Based on a phytosociological relevé it is shown that F. csikhegyensis grows in somewhat disturbed shifting sand communities belonging to the Cetrario aculetae-Corynephoretum. Probably, the population of Festuca csikhegyensis at the Harskamp finds its origin in an unintended anthropogeneous introduction.
