Aanwinsten voor de Nederlandse flora, hoofdzakelijk uit 1967-1974

In 1966 the decease of Th. J. Reichgelt caused a stagnation in the regular publication of acquisitions to the adventitious flora of the Netherlands. Only VAN OOSTSTROOM (1970a and b), ADEMA (1974), and VAN DER MEIJDEN (1975) incidentally continued this series. From 1975 onward the acquisitions to the adventitious flora of the Netherlands — and the new escapes from cultivation — are published in the annual lists with records of rare species. The present publication has the purpose of filling up the gap between 1967 and 1974 and includes: A. Native taxa — a few infraspecific taxa new for the Netherlands; B. Adventitious species; C. Species escaped from cultivation. In the lists B and C the original area of the species has been added.
