The data were fed into PC by dBase III Plus program. The HUNGPLANT database now is available by computer network, in BRS/SEARCH system, sponsored by the Coordination Office for Information Infrastructure (BAKONYI 1988). It consists of 3098 records in 21 fields. Key words: vascular plants, computerized database, Hungary INTRODUCTION The greatest problem of the coenological investigations is the heterogeneity of parameters to be disposed and used for evaluation. Researchers use in many instances different categories of coenological and floral elements even in the same country. Thus the data of different publications are not commensurable and the results are not comparable. Not only the dispersion of computers made the quick evaluation of data matrixes possible, but the evaluation and the comparison of the coenological samples have been made by standard way. Building this database was the first step to organize and standardize data into a modern information system and synthesize botanical, coenological, ecological and nature conservation knowledge of the Hungarian flora. Researchers of several institutes took part in building the previous test version (HORVÁTH 1990). The HUNGPLANT database contains latin names and the main paramètres of taxonomic, ecological and nature conservation ranks of the Hungarian vascular plants. MATERIALS AND METHODS HUNGPLANT is mainly based on SoÓ's Synopsis (1964-80) and on its supplementary volume by PRISZTER (1985). Consequently, some results on taxonomy of our flora published after 1985, were ignored. The occurrence data of * This work was supported by the Hungarian Research Fund (OTKA 3171).
