  Lajos Felföldy (1920–2016) was one of the most versatile and open-minded Hungarian biologists. He began his scientific career as a student of Prof. Rezső Soó. Between 1938 and 1946 he participated in geobotanical studies in University of Debrecen and Kolozsvár (Cluj-Napoca, Romania). He contributed with important achievements to the development of several biological disciplines. His pioneering study on the effects of air pollution on epiphytic lichens (1942) was among the firsts in the world. He described Hemitherophyte life-form as a discrete unit within Raunkiaer's plant life-form system (1942). He was a pioneer in the cytological (caryological) study of wild vascular plant species in Hungary (1947–1949). His results regarding to primary production of freshwater algae and algal culture (1958–1960) were in leading edge. In 1972 he founded and until 1990 edited the Hungarian series entitled ‘Vízűgyi Hidrobiológia’. Books of this series aimed to publish identification keys of freshwater taxa. These books were proved to be decisive and useful tools for Hungarian hydrobiologists in biological classification of brooks, streams, rivers and different types of stagnant waters. Between 1934 and 2009 he collected more than ten thousand herbarium sheets. After his retirement, he dealt with the revision of the herbarium material of Department of Botany in Hungarian Natural History Museum and Botanical Garden of Eötvös University (Budapest). He participated in the preparation of the New Hungarian Herbal. His scientific work was characterised by deep humility for nature, which was founded on strong theoretical and practical background.

  In the 20^th century Sándor Polgár was one of the most outstanding researchers of adventive plant species in Hungary. He wrote nine publications in this theme. In the industrial environment of his home town Győr (NW Hungary) he found tropical species, most of them were southern-American origin. The richest alien flora came around the oil factories of the town. He reported 65 taxa new for the Hungarian flora, four of them were new for Europe too. He was a great expert of problematic Solanum, Amaranthus and Chenopodium genera.

  The paper summarizes the previous history and recent purposes of the ‘Wildflower of the Year’ initiation, established in 2011. The main aim of this initiation is the promotion and familiarization of Hungarian flora, applying a public awareness campaign about the beauty, importance and ecological value of our spectacular wild plants. The ’Wildflower of the Year’ is selected by voting on internet (www.evvadviraga.hu). Starting from this volume the journal Kitaibelia publishes a monograph about the wildflower of the previous year.
