Abstract

In Hungary increasing problems are caused by hemp found in cultivated fields and waste areas. Results of nation-wide weed surveys demonstrate that area covered by and importance of the plant show a growing trend. The taxonomic status of weed hemp is not unambiguously cleared up in Hungary. Certain authors argue that weed hemp is the crop escaped and naturalized while others opinion is that in Hungary wild hemp is present spontaneously, too. Based on her ten years observations and surveys, the author gives the morphological characters of uncultivated hemp and attempts to clarify its taxonomic status accordingly.
