10 th <strong>Symposium</strong> on the Flora of Southeastern Serbia and Neighbouring regions,Vlasina 17 to 20 June 2010Taxonomic significance of primary volatile sulfur andphenolic compounds in the section AlliumBozin, B. 1 , Anackov, G. 2 , Zlatkovic, B. 3 , Orcic, D. 4 , Balog, K. 4 , Mimica-Dukic, N. 41 Faculty of Medicine, Department of Pharmacy, University of Novi Sad,Serbia2 Department of Biology and Ecology, Faculty of Sciences and Mathematics,University of Novi Sad, Serbia3 Department of Biology and Ecology, Faculty of Sciences and Mathematics,University of Niš, Serbia4 Department of Chemistry, Faculty of Sciences and Mathematics, Universityof Novi Sad, Serbiabbozin2003@gmail.comThe genus Alluim comprises between 750 and 850 species. According to thelatest intrageneric classification it is divided into 15 subgenera and 72 sections. Thesubgenus Allium is the largest, comprising around 280 species, 114 of whichcompose its largest section, Allium. Although extensive research has been done ongarlic and a few related species, there was no comprehensive study on thesignificance of primary volatile and phenolic compounds in the taxonomy of garlics.With respect to this, the chemical composition of phenolic and volatile sulfurfractions of 10 taxa of section Allium, including A. sativum (namely A. rotundumsubsp. waldsteinii, A. scorodoprasum, A. sphaerocephalon, A. atroviolaceum, A.guttatum subsp. dalmaticum and subsp. sardoum, A. vineale var. vineale, var.compactum and var. capsuliferum) was studied. Cluster analysis based on the mainphenolic (phenolic acids, flavonoids and anthocyans) and volatile sulfur compounds(different kinds of su lfides) pointed on the closest relation between A. sativum andthree investigated varieties of A. vineale. Second group made the examinedsubspecies of A. guttatum, joined with A. sphaerocephalon. A. scorodoprasum andA. rotundum subsp. waldsteinii presented the third group and A. atroviolaceum was,according to the linkage distance, the most distant from all other investigated taxa.18
10 th <strong>Symposium</strong> on the Flora of Southeastern Serbia and Neighbouring regions,Vlasina 17 to 20 June 2010Taxonomy, ecology and distribution of Acer hyrcanumFisch. & Mey. sensu latoTripic, R.Institute for Protection of Nature of Montenegro, Montenegrotripicr@t-com.meAcer hyrcanum was described as a new species by Fischer and Meyer (1837)from southeast Caucasus (mountain Talüsch in Azerbaijan). Taxonomy, ecology anddistribution of the species with seven subspecies: A. h. subsp. hyrcanum, A. h. subsp.stevenii (Pojark.) E. Murray, A. h. subsp. tauricola (Boiss. & Balansa) Yalt., A. h.subsp. shaerocaryum Yalt., A. h. subsp. keckianum (Pax) Yalt., A. h. subsp. reginaeamaliae(Orph. ex Boiss.) E. Murray and A. h. subsp. intermedium (Pančić) Bornm.are given in this paper. Acer hyrcanum s. l. prefers very specific ecologicalconditions and it is relatively rare in forest communities of Caucasus, Crimea, AsiaMinor and Balkan Peninsula. Today, different populations of the species are muchendangered, especially, by human impact which needs very sophisticated protectionmeasures. Also, the IUCN categorization for the territory of Montenegro is given inthe paper.The genus Plectania in MontenegroPerić, B., Perić, O.Micological centre, Biotechnical faculty, University of Montenegro, PodgoricaThe paper presents three species of the genus Plectania Fuckel 1870,identified in Montenegro: Plectania nigrella (Pers. : Fr.) Karsten, Acta Soc. FaunaFl. Fen. 2 (6) : 119, 1885, Plectania melaena (Fr.) Paden, in Korf, Mycotaxon 14(1):1 (1982), Plectania rhytidia f. platensis (Speg.) Donadini, Boll. Gruppo Micol. ‘G.Bresadola’ (Trento) 28(1-2): 24 (1985) and Plectania spec. Since this genus has notbeen studied in Montenegro up to now, the data presented here are new to the area.The material was collected in the Mediterranean, sub-Mediterranean and continentalregion of Montenegro. P. rhytidia f. platensis is a species that develops in very hotclimates, often with eucalyptus. In Europe was not so frequently observed. In ourcountry so far was observed only in two localities (Herceg Novi, Podgorica) inbroadleaf stands of Quercus spp. P. melaena and P. nigrella occur at continental andmountain sites, along the line of melting snow, in damp places, on lignicoloussubstrates. Both species were observed only in National Park Biogradska gora.Plectania spec. was found only in one site (Podgorica) in the introductory stand of19
