Language: Romanian with scientific nomenclature and name index
Please note, though billed by the authors as a field guide, its size and depth make this more a flora.
The classification system adopted is consistent with Ehrendorfer in the Lehrbuch der Botanik (1978), Soó in Synopsis Systematico-Geobotanico (1964-1973) and Flora Europaea (1964-1980, 1993) with some alterations. Species nomenclature was made in accordance with the botanical work Flora Europaea.
The identification of all the taxonomic positions, from the clade to the species and subspecies, is based on dichotomic keys, through the most important differential characters, most often with references to the ink-drawings and color pictures accompanying the text.
Each species in this field identification guide is accompanied by further information: scientific name, author (-s), the vernacular name in Romanian language (where available), life cycle (annual, biennial, perennial), life forms, height (between a minimum and maximum, in cm), the flowering or sporulation (the ferns) period, the frequency in Romania, the preferred habitat (-s), the number of chromosomes (2n), hints on where ecological optimum grows (e.g. soil moisture – U, the temperature – T, soil reaction (pH), light – L, soil mineral nitrogen – N, halophilous indices – S), phytosociology environment, some sozological mentions, the protection status and character of the relict species in Romania, the general area of distribution and the number that indicates the ink-drawing or picture accompanying the concerned taxon. For some species or subspecies, which are rare in the Romanian flora, the location data on districts or historic provinces, sometimes even the localities, are given; some taxa, whose presence is doubtful or have a controversial status in Romania bibliographic references are given.
The ecological indices are processed after Ellenberg et al. (1992), adapted to the physical and geographical conditions of Romania. The number of chromosomes is taken primarily from the works of Löve et Löve (1961). Plante Vasculare din România is accompanied by an explanatory index on plant morphology with technical terms used in determination keys that will help those less familiar with the botanical terminology. Plante Vasculare din România is ended with two indexes: of the scientific plant names and of the vernacular names.
