IntroductionIn the last two decades several comprehensive surveys and reviews were performed in many European countries on wild plant use. Wild plants formed important parts of our ancestors' diet in a multitude of ways (e.g. as bread ingredients, vegetables, fruits, spices, snacks or beverages); essential in severe times, supplementary otherwise [1][2][3]. Revitalization of traditional practices is timely for ecology, economy and nutrition biology. Nevertheless, even though Hungary is no poorer in traditions of wild plant use than other parts of Europe, no broad-scale review has been undertaken for Hungary in this respect, yet.Information on the human consumption of wild plant species is widely scattered among the ethnographic and botanic literature, mostly in Hungarian language. Publications on gathering economy, traditional nutrition, shepherding, forest goods utilization, and on the hunting-fishing-gathering "pákász" lifestyle in the former wetlands of the floodplains of the large Hungarian rivers are known from the end of 18th century on (e.g. [4]), and they became frequent from the second half of the 20th century. Publications of traditional research on medicinal uses of plants [5][6][7][8] and ethnobotany [9-11] also mention wild food plants, but a review concentrating on wild food plants is still missing.In this work we systematically review and compile information on the utilization of wild food plants in the Hungarian speaking regions of the Carpathian Basin from the Hungarian ethnographic and ethnobotanical publications. Our study aims at compiling a knowledge base on wild food plants consumed in Hungary and by the Hungarians living in other countries of the Carpathian basin, containing information on the species, as well as the modes of use. As the Carpathian Basin is dominated by alluvial floodplains located on the margin of the vast Eurasian steppe regions, Hungarian traditional plant use might also include previously undocumented usage of wetland and steppe plant species, which can potentially add some new aspects to the existing knowledge on traditional plant use in Europe.
