Een merkwaardige groeiplaats van Allium scorodoprasum L

A description of a locality in which Allium scorodoprasum is found along a canal near Heeten (province of Overijsel). The habitat is rather different from the usual habitat of this species, viz. a gradient between woodland and grassland on soils rich in lime. However, WESTHOFF (1968) described a locality in Belgium which is somewhat similar to the locality near Heeten; in both cases Allium scorodoprasum occurs in a hygrophilous more or less ruderal vegetation on a soil rich in nitrogen, and in both cases this vegetation contains some meadow grasses, a.o. Arrhenatherum elatius. On the fringe of woods and hedges where A. scorodoprasum occurs, the soil is rich in nitrogen too, and the species is often found in transitions of these shadowed vegetations to meadows.
