The presence of 592 taxa from the group of vascular plants was ascertained in the investigated area, with 566 species and subspecies recorded for the first time. Out of a total of 26 species listed in the literature for the flora of the Slavujevac area, the presence of 11 species has been confirmed. The presence of 45 plant species was recorded in the category of protected taxa, and 13 in the category of strictly protected taxa. The most common life form in the flora of the studied area is the form of hemicryptophytes present with 40.47% of the total number of recorded taxa. In the phytogeographical sense, the flora of the investigated area is dominated by species of the Mediterranean-sumediterranean (31.29%) and Eurasian (26.36%) area types, also including several Balkan endemic taxa.

U fitogeografskom smislu, u flori istraživanog područja dominiraju vrste mediteransko-sumediteranskog (31.29%) i evroazijskog (26.36%) areal tipa, uključujući i veći broj balkanskih endemičnih taksona. Ključne reči: flora, specijska raznovrsnost, floristički sastav, Slavujevac, Rujan planina, Srbija Introduction The part of the Balkan Peninsula that is characterized by a high diversity of flora and vegetation primarily refers to its southern part, including the southern parts of Serbia and the Republic of Northern Macedonia (Nikolić et al., 2007). Along the land border of the two mentioned countries, there is the mountain region including Rujan Mt., whose northern slopes include a specific area covered by our research. Weakened climatic as well as florogenetic influences from the Aegean Mediterranean area reach the southern parts of Serbia, including the investigated area, creating a characteristic composition and diversity of flora. The specificity of the richness of the plant world is especially noticeable in the thermophilic and xerophilous habitat types, which dominate the entire surroundings of the village of Slaujevac, located in the hilly and mountainous belt of the Rujan Mt. The first data on the flora around Slavujevac come from Ranđelović and Stamenković (1984), who in the second half of the 20th century presented the first data on the presence of certain plant species in this area. Two years later, emphasizing the botanical significance of this area, the same authors published the work “Flora i vegetacija Rujan planine u jugoistočnoj Jugoslaviji” with a large number of important data, some of which relate to the vicinity of Slavujevac (Ranđelović & Stamenković, 1986). Thanks to the great contribution of prof. N. Ranđelović, D.A. Hill and prof. V. Ranđelović, a new species of the genus Crocus was discovered in the area of this mountain, named Crocus rujanensis (Ranđelović et al., 1988). Mount Rujan, with the © 2022 Simić & Zlatković.

The aspect of endangerment and protection of rare species that occur in the area of Slavujevac, such as: Cachrys cristata, Opopanax hispidus and Alkanna pulmonaria, is discussed in detail in the “Crvena knjiga flore Srbije 1” (Ranđelović et al., 1983; Ranđelović et al., 1999; Niketić, 1999). Later, in the period from 2007-2018, more data on the flora of the investigated area appear, with some data again referring to newly discovered taxa in the flora of Serbia (Nikolić et al., 2007; Diklić & Stevanović, 2012; Stevanović & Gajić, 2012; Buzorović et al., 2013; Zlatković & Bogosavljević, 2014; Bogosavljević & Zlatković, 2018; Nikolić et al., 2018). The latest data from the researched area appears in 2021, when a new taxon (Knautia orientalis) was discovered for the flora of Serbia (Niketić et al., 2021). Although the flora of the Rujan Mt. has been completely processed (Ranđelović & Stamenković, 1984), a specific analysis of the flora around Slavujevac, for which a small number of specific floristic data is stated, was not done until 2015 (Stanković, 2015). Also, bearing in mind that more than 30 years have passed since the last thorough research of the flora of Rujan Mt., the aim of this paper is to present a list of flora, but also to indicate whether there have been some changes in the flora of this area which in geographical and phytogeographical terms. Materials and Methods Field research of flora covered the period from March to September 2014 and 2015, i.e. the period from March to September 2021 and from March to June 2022. The area covered by our research includes parts of the Rujan Mt. located near the village of Slavujevac (Amedan, Dedovica, Lismider,Majden, Mali Orljak,Veliki Orljak,), as well as several localities that make up its rural areas (Dolinska mahala, Garska mahala and Karadačka mahala). The investigated part of the area covers a total area of about 20 km2. The results of field research were documented with herbarium material that was herbarized, labeled and deposited in the Herbarium of the Faculty of Science in Niš (HMN). The collected plant material was identified using the keys of contemporary European monographs, including “Flora Europea” (Tutin et al., ed. 1968- 1980), as well as literature sources reference for the researched area (Josifović, ed. 1970-1977, Sarić, ed. 1986, 1992). The nomenclature is largely in line with the latest checklists, papers, monographs and databases (Tutin et al., ed. 1968 – 1980; https://www. europlusmed.org; http://www.worldfloraonline.org). The affiliation of taxa to the appropriate life form was also determined according to the Raunkiaer system (1934), which was supplemented by Mueller-Dombois, Ellenberg (1974), and developed for taxa at the level of Serbia by Stevanović (1992a). The method of Meusel et al. (1965, 1978), Meusel, Jäger (1992) was used to define the range of types and their adequate classification, which according to Stevanović (1992) was modified for the territory of Serbia. The legend for abbreviations of life forms and flora elements are shown in Tab. 1. Results and discussion The presence of 592 species from the group of vascular plants was ascertained in the investigated area. All recorded taxa were classified into 312 genera and 73 families. The number of 566 species was recorded for the first time in the vicinity of Slavujevac. Out of a total of 26 species listed in the literature for the flora of the Slavujevac area, the presence of 11 species was confirmed (Alkanna pulmonaria, Centaurea benedicta, Colchicum doerfleri, Crocus olivieri subsp. olivieri, Crocus pallasii subsp. pallasii, Crocus rujanensis, Jurinea polycephala, Knautia orientalis, Petrorhagia velutina, Trifolium cherleri, Vinca herbacea).

Overview of the 10 richest families in the flora around Slavujevac BIOLOGICA NYSSANA ● 13 (2) December 2022: 89-107 Simić & Zlatković ● Flora around Slavujevac on Rujan mountain (SE Serbia) 91 presence of 15 species listed in the literature for a given area has not been confirmed by our field research. The group Pteridophyta (ferns and horsetails) includes 3 genera, 3 families and 3 species (0.51% of the total number of species) of the flora of the study area. Within the group Spermatophyta (seeds), the class Coniferopsida (gymnosperms) is represented by 1 genus, 1 family and one species (0.17%). The species seeds from the class Dicotyledones are by far the most numerous, comprising representatives of 251 genera, 59 families and 486 species (82%). The class Monocotyledones is represented by 57 genera, 10 families and 102 species (17.32%). In relation to the number of species with which they are represented in the flora of the researched area, the following families have the highest species richess: Compositae (73 species), Leguminosae (67) and Gramineae (45). Families represented with one genus and one species are: Aspleniaceae, Athyriaceae, Alismataceae, Araceae, Amaranthaceae, Anacardiaceae, Asclepiadaceae, Corylaceae, Cupressaceae, Dioscoreaeceae, Equisetaceae, Globulariaceae, Haloragaceae, Onagraceae, Orobanchaceae, Protulaceae, Saxifragaceae, Thymelaceae, Tiliaceae and Verbenaceae. The richness of the flora around Slavujevac as well as the total flora of hilly and lower mountain region of the southern parts of Serbia is associated with the fact that the investigated area has a transitional phtogeographical position, i.e. that it is located in the transitional zone between the Mediterranean-submediterranean and Pontic-South Siberian floristic region (Zlatković, 2011).

From the aspect of species conservation, taxa that enjoy one of the two forms of legal protection at the national level on the basis of the Law on Nature Protection are of importance in the researched area (Official Gazette of the Republic of Serbia, No. 36/09). The first group is represented by plants that are on the list of strictly protected wild species of plants, animals and fungi, the collection of which is prohibited on the territory of the whole of Serbia, i.e. possible only with the permission of the ministry responsible for nature protection. This group refers to 16 species present in the flora of Slavujevac. The second group consists of species that are not critically endangered, and whose collecting is allowed only in limited quantities, i.e. controlled on the basis of their presence on the list of Protected Wild Species of Plants, Animals and Fungi. The mentioned group is significantly larger in relation to the previous one and includes a number of 47 species present in the flora of Slavujevac. Lists of protected species from the two mentioned categories are shown in Tab. 3 and Tab 4. Table 3.

It should be emphasized that all 26 taxa listed in the literature for these sites have been critically reviewed. If no evidence has been found for a particular taxon listed in the scientific literature during field research, a free assessment of the correctness of the literature citation or possible correction of the citation is given on the basis of a comprehensive analysis of the taxon distribution. In a small number of cases, a dilemma remained regarding the correctness of the literature citation, with such data marked as suspicious or negative.

(Ranđelović and Stamenković, 1984) Veliki Orljak, Dedovica The most common life form in the flora of the investigated area (Fig. 1) is the form of hemicryptophytes (H) present with about 40.47% of taxa. With a slightly smaller share in the total flora follows the group of therophytes (T), about 35.37% of the total number of species. Since the two mentioned groups of plants have an almost codominant relationship in the overall ecological spectrum of the flora of Slavujevac, it can be said that it has a hemicryptophytic-terophytic character. The life forms of geophytes (G), phanerophytes (P) are also relatively well represented, while other life forms are far less represented in the studied area. Hydrophytes (Hyd) are the least represented (0.51%). Such a small number of hydrophytic species is explained by the lack of habitats suitable for the development of aquatic plants. The flora of Slavujevac is characterized by the largest share of hemicryptophytes, which is, in general, a characteristic of the flora of the largest number of areas in the temperate climate zone. However, the flora of Slavujevac is characterized by only a 5% lower share of therophytes in relation to the life form of hemicryptophytes. The conspicuous percentage of the mentioned life form in the flora of this area indicates significant climatic zone from the Mediterranean submediterranean area, and above all the pronounced dry period during the vegetation season which favors the appearance of annual plants as the best adapted ecological groups of plants to hot and dry habitat conditions. Based on the horological analysis of the flora Slavujevac area, 8 basic habitat types were singled out. In the area spectrum of the flora of the investigated Fig. 1. Representation of life forms (%) in the biological spectrum of the flora of Slavujevac (Ch– chamaephytes; G–geophytes; H–hemicryptophytes; Hyd–hydrophytes; P– phanerophytes; T–therophytes) 95 BIOLOGICA NYSSANA ● 13 (2) December 2022: 89-107 Simić & Zlatković ● Flora around Slavujevac on Rujan mountain (SE Serbia) area (Fig. 2), the Mediterranean-submediterranean area type (31.29%) and the Eurasian area type (26.36%) are dominant. These two area types make up a total of 57.65%, i.e. more than half of the total flora of Slavujevac. The explanation for the dominance of the mentioned range types lies in the relatively low altitude of the area, while the emphasis of the Mediterranean-submediterranean elements is explained by the strong florogenetic influence from the Aegean Mediterranean area through the lowland area of Macedonia and Northern Macedonia. A significant percentage of the flora of the investigated area belongs to both the Central European (12.92%) and the Pontic area type (12.58%). Indicating strong anthropogenic influences, the group of cosmopolitan plants is also well represented (10.03%). Other range types are represented by a much smaller number of plant taxa. Fig. 2.

Schmidt (H, MED) Conclusions Floristic influences from the southern part of the Balkan Peninsula strongly influenced the flora of southern and southeastern Serbia. For that reason, the flora of Rujan Mt., including the surroundings of the village of Slavujevac is largely specific and diverse and requires more detailed botanical research. The presence of 592 plant species, 312 genera and 73 families of vascular plants was established by recent floristic research in the area of Slavujevac. Only a small number of taxa are listed in the available literature for the vicinity of Slavujevac. Of that number, only the presence of 11 taxa was confirmed during our field research. At the same time, Arabis glabra subsp. pseudoturritis, Goniolimon collinum and Hippocrepis biflora are incorrectly listed for the studied area. The species of Pteridophyta, as well as gymnosperms, are represented by a poor number of species. Taxa from the group Dicotyledones are by far the most numerous with about 82% of the total number of flora in the investigated area. Taxonomic analysis shows that the families Compositae, Leguminosae and Gramineae are the richest in species and subspecies. Analysis of the biological spectrum indicates the dominance of the hemicryptophytes and therophytes in the flora. In the phytogeographical sense, the species of the Mediterranean-submediterranean and Eurasian area type prevail, including 10 species belonging to the group of Balkan endemic taxa. A large presence of plants from the group of endangered taxa was found in the investigated habitats. This area is floristically rich, but it is also exposed to numerous negative anthropogenic factors. It is necessary to educate the local population in order to reduce the rate of destruction of natural habitats in the area. Also, it is necessary to valorize Rujan Mt. by the organizations for nature conservation in order to preserve this floristically rich and diverse mountain for a longer period of time.
