For the first time in 30 years is Dr. S. J. van Ooststroom no longer one of the composers of ‘the list’. We have made a comparison between his first list (in 1948) and his last (1978). The list of new localities of rare species and interesting records of the more common species found in the Netherlands mainly during 1979, has been subdivided into three categories: A. Netherlands species; B. Adventitious species; C. Species escaped from cultivation. As the first part of the Atlas of the Netherlands Flora has appeared, additions and new records of taxa inserted in this atlas will be published separately. Category A includes the species – also naturalised ones – belonging to the Netherlands Flora, as established by the Floristic Council in 1975 and inserted in the Standard List of the Netherlands Flora 1975. In list A comments have been added, where necessary; adventitious records of Netherlands species are indicated with adv., escapes from cultivation with verw. In list B and C the names of the taxa new for the Netherlands, are in bold type.
