The “Cämpia Transilvaniei” is characterized by a high diversity of vegetal taxa; the checklist of flora in this area reveals a count of 716 vascular taxa, meaning 692 species, 24 subspecies and 2 forms, belonging to 96 plant families. The paper analyzes the floristical diversity of the studied area taking into consideration the presence of some micro arealophyte species, endemic species, Balkanic and Mediterranean species which gives specificity to the flora of “Cämpia Transilvaniei”. The presence of some rare, threatened, vulnerable plants of communitarian interest that are listed in National Red Lists is also revealed in the report. Alien plants, an important group of plants identified in the field are present. Cataloging these alien plants is important to understand the spread of these populations and how their growth detrimentally impacts the indigenous species. Keywords: floristic diversity, rare, threatened, vulnerable, endemic species, Cämpia Transilvaniei Introduction The impact on the taxonomic diversity of biospheres reveals breadths and intensities that could not have been suspected a few decades ago. One of the biggest tasks of contemporaneity is the conservation of flora and fauna of the planet impacting a greater number of species, regardless of their biological importance. Accordingly, the main focus of nature conservation has become an endeavor to protect taxonomic diversity of populational components of natural and semi-natural ecosystems with their genetic structure [3]. The Transylvanian Plain is located in the the central part of the Transylvanian Basin. It has approximately 5,000 square kilometers and spreads across parts of three counties: Bistrija Näsäud, Mure? and Cluj. In Mure? county, the Transylvanian Plain, north of the River Mure? (Fig. 1) is a lowland region consisting of gently rolling hills (average elevation - 400 m), with wide valleys formed by the tributaries of the river Mure? crossing among the hills. The part of the Transylvanian Plain situated in the Mure? County is called the Mure? Plain and includes the Hilly Plain Särma? (situated almost entirely in the Transylvanian Plain domes) and Madara? Hills (located in the eastern section of the Mure? Plain next to the Reghin Hills). M A R I S I A, XXXV, p. 17-26
