Stollmayer-Boncz, Emilia: The flora of Réti-dűlő near Csömör

carnata is a protected, potentially endangered species. It blossoms in May, when its flowers of different shade from light rose to deep purple are so plentiful in the middle of meadow that it is hard to avoid stepping on them. Edificator species occurring at the edge of meadow towards the reeds include Salix cinerea (also represented in the meadow by juvenile specimens), Carex acutiformis, Carex distans, and Molinia hungarica. Accompanying species, such as Equisetum palustre, Achillea asplenifolia, Angelica silvestris, Cirsium canum, Galium verum, Lotus tenuis, Sanguisorba officinalis, Tetragonolobus maritimus subsp. siliquosus, Briza media, Carex flacca, Carexpanicea, and Elolcus lanatus are found in the greatest number. These species with beautiful and colourful flowers keep the meadow in magnificient blossom from spring to autumn. There are only five disturbance-resistant species: Centaurea pannonica, Lychnis flos-cuculi, Prunella vulgaris, Ranunculus acris, and Vicia cracca. Their purple and yellow flowers also add to the colours of meadow. A weed species of small size, Carex hirta is abundant especially towards the village. There are 9 Molinio-Juncetea, and 9 Molinio-Arrhenatheretea species. The swamp meadow with blue meadow-grass forms a colourful carpet from May till September. The mowing in May interrupts the splendour of flowers for only a short time, owing to the high ground water level. 48 species are common in the meadow. Strictly protected (KV) is Carex appropinquata. Epipactis palustris is protected (V) and endangered (**), whereas Eriophorum latifolium is protected (V) and potentially endangered (*). The 15 accompanying species (K) are the following: Caltha palustris, Chrysanthemum leucanthemum, Galium palustre, Glechoma hederacea, Leontodon hispidus, Lysimachia nummularia, Mentha longifolia, Myosotis palustris subsp. strigulosa, Rhinanthus minor, Symphytum officinale, Trifolium hybridum, Valeriana dioica, Carex gracilis, Carex vulpina, Poa pratensis. The 9 edificator species include the following: Salix alba, Agrostis stolonifera, Alopecurus pratensis, Festuca pratensis, Juncus subnodulosus, Phragmites communis, Poa angustifolia, Schoenus nigricans, and Scirpus silvaticus, which is rare in the Great Hungarian Plain. The 17 disturbance-resistant species (TZ) are the following: Daucus carota, Lathyrus pratensis, Odontites rubra, Ononis arvensis, Ranunculus repens, Rumex acetosa, Senecio erratus, Trifolium campestre, T. pratense, Urtica dioica, Calamagrostis epigeios, Dactylis glomerata, Festuca arundinacea, Juncus compressus, J. effusus, J. inflexus, and Poa triviális. Weeds are represented by four species: Equisetum arvense, Cirsium arvense, Ononis spinosa, and Pulicaria dysenterica. Among the rarer species Colchicum autumnale (K) with its purple flower in autumn is noteworthy, as it is not common in the Great Hungarian Plain. In the reeds located between the brook and the meadow, abundant species are Calystegia sepium (K) and Phragmites communis (E), whereas common species include Epilobium hirsutum (K), Myosotis palustris subsp. strigulosa (K), Vicia cracca (TZ), Alopecurus geniculatus (TZ), Carex acutiformis (E), Carex flacca (K), Carex hirta (GY), and Carex vulpina (K). The brook bank is dominated by trees and bushes, soft-stemmed plants are subordinate. Salbe alba (E) is abundant and it lends exceptional beauty to the scenery in windy and sunny weather. The moss species Leptodictyum riparium is common. Other common species include Humulus lupulus (TZ) which creeps onto all kind of trees, Populus nigra (E) and Salix fragilis (K) of giant size, Sambucus ebulus (GY) which is white in late spring and black in autumn, the climbing Solanum dulcamara (TZ), the creeping Solidago gigantea (K), and the pungent Urtica dioica (TZ). Many medicinal herbs and spice plants occur in the area. There is no special reference to them in this paper since their collection is prohibited in the nature reserve, although their role as a gene bank is significant. The Csömöri-legelő (pasture) was designated as a nature reserve in 1977 primarily for the Csömör pool and its valuable scenery. The Réti-dűlő with its seven protected species (Carex 'MS
