Enkele vondsten van de scherpe pinksterbloem in West-Nederland

The author describes the habitat of Cardamine pralensis L. subsp. picra De Langhe et D’hose near Amstelveen in the Haf district and concludes that this subspecies is also found in places that differ strongly from those described in other publications. It might be useful to check whether this taxon can be sufficiently separated from the subsp. pratensis on the basis of chromosome counts.
