Dobolyi, Konstantin Z., Horváth, Ferenc , Lőkös, László; Szerdahelyi, Tibor: Database of the Hungarian vascular plants (HUNGPLANT)

taxa were disregarded in case of insignificant importance, likely extinction or doubtful reference. In the course of the database building a standardization of the information was necessary to terminate the heterogeneity of data, thus a reasonable simplification and reduction of the Synopsis entries were achieved. In absence of adequate information the subspecies field category is the same as the species field. To offer a better arrangement for the users we reduce the great number of floral element categories to a definite limit and sorted the entries as follows: the most important information are given in the Fll field and the accessory data are in the F12 field. Most of the TWR values correspond to Prof B. ZÓLYOMI'

s publications (1964, 1966). Missing data were discussed and completed by Prof T. SIMON in the Department of Plant Taxonomy and Ecology, Loránd Eötvös University, by using and collecting data of Prof P. JAKUCS, Prof T. PÓCS and Dr A. HORANSZKY. The greatest difficulties were caused by the heterogeneity of the coenological characters. Similarly to the floral element categories, two fields were set up again for each species (or subspecies). The most characteristic association (-group) are given in the Ccl field, while the less characteristic, but still important association(-group) are given in the Cc2 field. Data used in HUNGPLANT had been compared in details with the data of the new plant identification handbook (SIMON 1992) before that book was published.
