Nieuwe vondsten van zeldzame planten in 1991 en 1992

Najas minor was found again after 85 years of absence. Four species have for the first time crossed the border of the Netherlands, while extending their range: Bidens radiata, Bupleurum falcatum, Callitriche brutia, and Scirpus holoschoenus. Possible recent immigrants are Hypericum androsaemum, Leucanthemum paludosum and Polycarpon tetraphyllum. It is unlikely that Cerastium brachypetalum and Helichrysum arenahum are again part of the Dutch flora.
