Emlékezés Boros Ádámra, születésének századik évfordulóján
Molnár V. Attila
Ádám Boros is one of the greatest representatives of Hungarian floristical research. First of all he is known as bryologist, but we remember here him as the most successful and many-sided scientist of vascular flora of Carpathian Basin. He was born in Budapest on 19th November 1900. In the elementary school he already discovered the plant kingdom for himself. In his tens he enthusiastically walked the surrounding of Budapest, collecting and identifying plants. His masters were Sándor Jávorka and Árpád Degen. He attended university between 1918 and 1922 and defended his University Doctor theses at his age of 22. Later he worked for different institutes of pharmacy and agrobotany till his death in January 1973. His real passion was the research of flora in the Carpathian Basin. He spent almost 2000 days (about 6 years) with field work. In his first scientific work published in journal Botanikai Közlemények he summarised his floristical data collected until the age of 16. The mosses attracted his interest after that period, at his age of 17 and step by step he became possibly the most prominent bryologist of Hungary. Later he tried to cover all parts of the country, mostly by train. One of the greatest result of these trips is the finding of Lake Baláta where he recorded dozen of rare and interesting species, including the e.g. Aldrovanda vesiculosa, Ludwigia palustris, Caldesia parnassifolia and Sparganium minimum. During the 2nd World War he visited the reannexed areas of Hungary by bicycle. He took really successful journeys to Mura river region, Bácska and Transylvania too. The floristical results of these trips can only be compared only to Pál Kitaibel’s research trips. Several floristical novelties are linked to his name. He published basic works on the flora of Gerecse-, Pilis- and Velence Mountains, Mezõföld and Kiskunság. He dealt with sandy forests, marshy forests and meadows, alkalic vegetation, Sphagnum bogs of Pilis, Bakony, Balaton Highland, Vendvidék, North Hungarian Mountains and Transylvania, loess walls, marshes, floodplains, ice caves and cave-mouths, thermal waters, lakes, sand pits, rice fields etc. Among the flowering plants, only to mention a few, he dealt thoroughly with the species of the following genera: Verbascum, Elatine, Sorbus, Potamogeton, Centaurea, Hieracium, Carduus. His publications on the flora of Somogy (1924a) and Nyírség (1932) can be considered as a forerunner of Hungarian critical floristical works. His herbarium was the largest private one in Hungary, containing almost 65,000 sheets of vascular species and about 130,000 moss and liwerworth-samples. Today it is the part of the collection of the Hungarian Natural History Museum in Budapest. His field diaries containing data between 1915 and 1971 form 51 bulky volumes. The number of his publications exceed 700 items, out of which the scientific ones number about 230.The field research formed the organic part of his life. Few months before his death in October 1972, he still collected in the Tátra Mountains with László Vajda, his good friend and co-worker.
