Botany

The floristic diversity of “Cämpia Transilvaniei” (Mures County) The sozological categories for each species are according to IUCN and the red lists used. An increasing major threat to indigenous biodiversity in Europe and worldwide is invasive species. Because of the negative impact invasive species have on habitats and native species it is important to identify them. To accomplish this, systematic monitoring researches of the popula­tions in their habitats is required. The invasive species recorded in the studied area were estab­lished by Anastasiu, P. & Negrean, G. [1, 2] and Dihoru, G. [6]. Results and discussions As a consequence of the regional localization, of the diversity of relief (hills, meadows) and of the diverse expositions and inclination of slopes, The Transsylvanian Plain is characterized by a diversity and richness of vegetal taxa: 716 taxa including 692 species, 24 subspecies and 2 forms belonging to 96 plant families. The number of species in the Transylvanian Plain deter­mined so far is 20.45% of all known species of our country (3500 species after Flora R.P.R. and R.S.R.). This significant percentage allows us to appreciate that the studied area is a region with a rich and varied flora. [13] Out of this flora a remarkable phytogeographical interest has some micro arealophyte species, endemic and subendemic species. Thus, between endemic species we mention Aconitum lycoctonum L. em. Koelle ssp. moldavicum (Hacq.) Jalas (End. Carp.), Pulsatilla pratensis (L.) Mill, ssp. flavescens (Hazsl.) Holumb (P pratensis (L.) Mill. ssp. hungarica Soó) (Pan-End), Pulsatilla vulgaris Mill. ssp. grandis (Wender.) Zämels (Eur (centr.)-End), Cephalaria radiata Griseb. et Schenk (End), Salvia transsylvanica (Schur ex Griseb.) Schur (JLnA), Jurinea mollis (L.) Reichenb. ssp. transylvanica (Spreng.) Nyman (subEnd.), Delphinium simonkaianum Pawl. (End). The presence of the Daco-Balkan and Ponto-Balkanic floristic elements give a particular aspect of this area, demonstrating the intensity of their differentiation and conservation of tertiary and Pleistocene flora. The presence of some phyto-historical interference in the distant past with the Balkan peninsula and Anatolia is attested by Balkan species. Out of the Balkanic elements in study area we mention: Melampyrum bihariense A. Kern.(Dac), Allium denudatum F. Delaroche (Allium albidum Fischer ex Bieb. ssp. albidum, Allium flavescens Besser, Allium ammophilum Heuffel) (Pont-Dac-Balc), Linum flavum L (Pont-Pan-Balc), Euphorbia epithymoides L. (Euphorbia polychroma A. Kern.) (Eur-Balc), Trinia ramosissima (Fisch. exTrevir.) W. D. J. Koch (Pont-Pan-Balc), Cephalaria uralensis (Murray) Roem. et Schult (Pont-Balc), Ajuga laxmannii (Murray) Benth. (Pont-Pan-Balc), Rhinanthus rumelicus Velen. (Pont-Pan-Balc), Scrophularia scopolii Hoppe (Pont-Pan-Balc), Veronica orchidea Crantz (Pont-Pan-Balc), Asyneuma canescens (W. et К.) Griseb. et Schenk (Pont-Pan-Balc), Carduus hamulosus Ehrh. (Pont-Pan-Balc), Centaurea stoebe L. ssp. australis (A. Kern) Greuter (Centaurea biebersteinii DC. ssp. biebersteinii) (Pont-Pan-Balc), Inula ensifolia L. (Pont-Pan-Balc), Serratula radiata (Waldst. et Kit.) Bieb. (Pont-Pan-Balc), Allium paniculatum L. (Pont-Pan-Balc), Iris pumila L. (Pont-Pan-Balc), Iris variegata L. (Pont-Centr-Eur-Balc), Muscari tenuiflorum Tausch. (Pont-Pan-Balc), Polygonatum hirtum (Bose ex Poir.) Pursh (Polygonatum latifolium (Jacq.) Desf.) (Pont-Pan-Balc), Helleborus purpurascens W. et K. (Carp-Balc-Pan), Corydalis solida (L.) Clairv. ssp. slivenensis (Velen.) Hayek (Bale), Goniolimon tataricum (E.) Boiss. (Pont-Pan-Balc), Cytisus albus (Hacq.) Rothm. (Pont-Pan-Balc), Cytisus hirsutus L. ssp. leucotrichus (Schur) A. Eöve&D. Lőve (Cytisus leuco­­trichus Schur) (Balc-Pan), Lathyrus pallescens (M. Bieb.) K. Koch (Pont-Pan-Balc), Lathyrus pannonicus (Jacq.) Garke (Eur (centr.&NV)-Balc). The high number of Balkanic and Mediterranean species prove the steppic character of this area. 19
