  The present article is the second part of the series aiming to contribute with new data to the distribution maps published recently in Atlas Florae Hungariae. Current occurrence data of 612 vascular plant taxa from 283 flora mapping quadrates (CEU) are presented. New records are distributed over the entire Hungary, however, most are localised in the North Hungarian Mts. Occurrence data of rare native taxa (e.g. Antennaria dioica, Bupleurum pachnospermum, Carex rostrata, Ceratocephala testiculata, Cicuta virosa, Cirsium boujartii, Epipactis moravica, Lycopsis arvensis, Parnassia palustris, Pyrus nivalis, Rumex kerneri, Rumex pulcher, Silene nemoralis, Stellaria alsine, Teucrium botrys, Vicia lutea), rare or data-deficient alien taxa (e.g. Nonea lutea, Panicum dichotomiflorum, Silybum marianum) as well as frequent but more or less underrepresented taxa (e.g. Eragrostis minor, Heliotropium europaeum, Saxifraga tridactylites) are also enumerated, since our intention was to fill the gaps in the Atlas. Remarcable contribution on the occupied territory of Ranunculus illyricus and Spergula pentandra in the Nyírség region (E Hungary), and on the Hungarian distribution of expanding alien weed Senecio vernalis are also presented.

  The paper summarise occurrences of some rare invasive weeds of Hungary. We found currently second population at the Australian origin Chenopodium pumilio in Budapest (Zugló) in September 2016. Further, 27 occurrence data of 8 other species (Amaranthus deflexus, Echium maculatum, Lepidium densiflorum, Oxybaphus nyctagineus, Panicum dichotomiflorum, Portulaca grandiflora, Sarothamnus scoparius, Tragus racemosus) is also reported in the persent paper from the ‘Északi-középhegyég’ area (Northeast-Hungary), and some data from beside the Hungarian–Slovakian border, especially settlements, strongly disturbed places (especially road curbs, pavement cracks, train stations), indicating the Central European flora mapping system quadrate number. Voucher specimens were deposited in herbarium of Hungarian Natural History Museum, Budapest (BP).
