Detailed and long-term field studies confirmed the presence of 492 Balkan endemic species and subspecies in the investigated area. The most important contributors at family rank in the Balkan endemic flora are Asteraceae, Caryophyllaceae, Fabaceae, Brassicaceae, and Lamiaceae, with Hieracium, Dianthus, Centaurea, and Silene being the genera with the highest number of endemic taxa. In the chorological and life form spectra of the Balkan endemics, taxa from South European and Central European mountainous chorological groups and hemicryptophytes and chamaephytes are the most abundant. The presence of endemic plants in 11 geographical provinces in Central Serbia and Kosovo regions was also analyzed and cluster analysis was used to classify the geographical provinces according to their floristic similarities. The final analyses of distribution and magnitude of endemism include summary mapping of all the endemic taxa at 10 × 10-km Universal Transverse Mercator maps. High-mountainous areas of Mts Prokletije and Mts Šar-Planina are distinctive centres of richness and diversity of the Balkan endemic flora in Central Serbia and Kosovo regions. Most endemics were recorded on limestone and at 1500-2000 m a.s.l. Vegetation classes Asplenietea trichomanes, Festuco-Brometea, Elyno-Seslerietea, and Erico-Pinetea are the richest in endemic taxa. A catalogue of the Balkan endemic taxa in Central Serbia and Kosovo regions, with their threatened and legally protected status, is also presented.

He dedicated most of his life to investigate the flora of Southern Serbia as well as Albania and the Former Yugoslav Republic of Macedonia. Since he was working at the Institute of Botany and Botanical Garden in Belgrade, the majority of his collection is deposited in BEOU. While describing new taxa, in most of his publications he did not indicate the holotype. The present study discusses the lectotypification of 7 names published by Košanin alone, or with his contemporaries.

Montenegro, E. Bosnia and W. Serbia. The comparative morphoanatomic investigations have included four distantly separated populations of the species D. malyana, i.e. two from Serbia, from the ravines of Sokoline and Vranjak on Mt. Tara, and two from Montenegro, in the canyons of the Tara and Piva rivers. Comparative morphoanatomical studies have shown the presence of general adaptive characteristics of a specific, conservative xeromorphic type, slightly differing in each population. Principal component analysis (PCA) and canonical discriminant analysis (CDA) of 20 morphoanatomical characteristics of the leaves and stems have shown a clear distinction between the populations from the river Piva canyon (Montenegro) and those from the Sokoline ravine (Serbia), on one side, and those of Vranjak gorge (Serbia) and of the river Tara...

Four plant taxa are a novelty for proper Serbia, Vojvodina, or Kosovo and Metohija, and for 7 plants, presence in certain administrative units in Serbia has been confirmed. In the last part of the paper, there is a review of 9 disputed taxa for our country.

Although numerous studies about their ecology have been carried out concerning calcareous areas, little is known about orchids that occur in serpentine habitats. The aim of this study was to investigate the ecological preferences of orchids in serpentine and non-serpentine areas on the model of the Valjevo Mountain Range (W Serbia). Niche analysis of orchids was performed using outlying mean index analysis. Data concerning geographical coordinates, altitude, habitat type, inclination, bedrock type, light regime, soil moisture, acidity, nitrogen and temperature were used as explanatory variables. Data of 33 orchid taxa from 407 localities were analysed. The most important gradients that govern orchid distribution were geological bedrock, light regime and temperature. The results have shown that only Anacamptis morio and Gymnadenia conopsea have statistically significantly larger populations on serpentine compared with non-serpentine bedrocks. This study highlights the importance of serpentine habitats as orchid habitats, bearing in mind the occurrence of rare species and species which were found exclusively in serpentine habitats.
