Florisztikai megfigyelések a Délnyugat-Dunántúl gyomvegetációján
The studied area is at the South-West part of Hungary, on the boundary of three floristic regions (Pannonicum, Praeillyricum and Noricum). The paper shows forty weed species which are present in this area. Some species are of Eurasian chorotypes are common in Hungary in general, but regionally are rare e.g. Amaranthus crispus, Atriplex tatarica, Atriplex acuminata, Xanthium spinosum, Xanthium strumarium, Heliotropium europaeum. Eurasian chorotypes. Aphanes microcarpa, Sherardia arvensis, Hypericum humifusum and Eragrostis cilianensis are rare and endangered species in Hungary. They live on stubble-fields and extensive agricultural fields. Solidago canadensis is a species of North-American origin, infrequent in the studied area and it is common species in North and East Hungary. It has spread along Lower-Zala-Valley in North-East part of the studied area. Where S. gigantea is much more frequent than S. canadensis. Fallopia japonica is also important geophyte weed in this area. It grows mostly in Lower-Zala-Valley and along brooks and non-agricultural habitats.
