    The present study reports occurrence data of 26 vascular plant taxa, collected in Pannonhalma Hills, including sush species as  Epipactis palustrisOphioglossum vulgatumOrnithogalum × degenianum and Ornithogalum sphaerocarpumPhlomis tuberosa was re-discovered 150 years after the first found. Some new localities of Ophrys sphegodes and Ophrys apifera are reviewed. After the enumeration of localities, chorological and geobotanical remarks and population dinamical comments are also presented.In the article we commemorate the benedictine votaries Flóris Rómer and Valér Ballay, who were the starters of botanical reveal of the flora of Pannonhalma Hills.

    New and recently confirmed localities of 52 rare taxa (including 26 orchids) are presented from the vicinity of Budapest. Epipactis peitzii is a new species for the Hungarian flora; it has been recorded in the Buda and Pilis Mts. This species and its closest relatives (E. leptochila group) are briefly discussed. Other records are new for the flora of particular regions, specifically: Buda Mts: Corydalis intermediaEpipactis leptochilaEpipactis muelleri; Pilis Mts: Anacamptis coriophoraEpipactis neglectaE. tallosiiValerianella pumila; Visegrád Mts: Epipactis futakiiE. leptochilaE. muelleriE. neglectaOphrys apiferaO. holubyana.

    We report the occurrence data of 44 vascular plant taxa collected at various localities in Hungary (mainly the Danube–Tisza Interfluve and South Transdanubia) during floristic, vegetation and ecological field surveys between 2016 and 2018. Of the species in the present article, 27 are protected or strictly protected. In the paper we focused on plants that are rare regionally (e.g. Botrychium lunaria, Polystichum aculeatum) or in the whole country (e.g. Ophrys oestrifera, Ranunculus psilostachys), as well as on plants that occurred in unusual habitats (e.g. Corydalis solida). We also included new localities of weedy species, some of which (e.g. Opuntia humifusaSporobolus cryptandrus) may present nature conservation threats.
