Cyril and Methodius University, Arhimedova 66, 1000 Skopje, Republic of Macedonia ABSTRACT: During several botanical expeditions in the Republic of Macedonia (Mt Jablanica and Mt Baba: Pelister), a new genus Amphoricarpos Vis. and five new species for the flora of Macedonia were found: Euphorbia montenegrina (Bald.) K. Malý ex Rohlena, Prangos ferulacea (L.) Lindl., Tanacetum larvatum (Griseb. ex Pant) Hayek, Amphoricarpos autariatus Blečić & E. Mayer and Allium phthioticum Boiss. & Heldr. Most of them are mountainous Balkan (sub)endemics with less than 30 populations and with the center of distribution in southeastern Dinaric Alps. In this paper we discuss the phytogeographical importance of these five plants in the light of their new, more accurate distribution ranges in the Balkan Peninsula. In addition, new floristic records for the same species in the neighbouring Balkan countries (Albania, Montenegro and Serbia) are also presented.

Niketić et al: New species for the vascular flora of Republic of Macedonia and their distribution in the Balkan Peninsula 59 findings for the flora of Macedonia are regularly published in addition to monographic publications (Matevski 2002, 2002-2003; Matevski & Teofilovski 2004, 2011; Matevski et al. 2005, 2008, 2011; Niketić et al. 2007; Dimitrov 2007a, 2007b, 2011, 2012; Matevski & Kostadinovski 2009; Stevanović et al. 2009, 2010). Because of these characteristics, 42 Important Plant Areas were recently identified across Macedonian territory (Melovski et al. 2010). This paper represents the continuation of floristic and chorological studies of the vascular flora of the Republic of Macedonia. Five new species for the flora of Macedonia, collected at different localities on southwestern mountains Jablanica and Pelister, are presented in this paper. New findings for the same species in surrounding Balkan countries (Albania, Montenegro and Serbia) are also presented. MATERIAL AND METHODS The study was based on fieldwork in Mt Jablanica during the years 2006 and 2013 as well as in Mt Pelister in 2012. Besides the field survey, checking and revision of herbarium material and relevant literature sources were used for supplementation of the distribution records. Distribution of the species in the Republic of Macedonia and the Balkan Peninsula was mapped on 10 × 10 sq. km using the UTM grid system (UTM Zones 33-35T). New Fig. 2. Distribution of the species Euphorbia montenegrina (Bald.) records included findings that had not been registered in K. Malý ex Rohlena in the Balkan Peninsula the literature for individual UTM squares so far. Imprecise records relate to wider localities which included two or Helioscopia into the separate section, E. sect. Chamaebuxus more UTM 10 × 10 squares. Lázaro. There is a widespread opinion that E. montenegrina Collected plant material was deposited in the belongs to the E. epithymoides group, which includes five Herbarium of the Institute of Botany and Botanical closely related species and subspecies centered in the Balkan Garden “Jevremovac”, University of Belgrade (BEOU), the peninsula (Smith & Tutin 1968). This opinion was not Herbarium of the Natural History Museum in Belgrade supported by molecular analysis (Riina et al. 2013) which (BEO) and the Herbarium of the Naturhistorisches indicated that E. montenegrina is in a separate clade from Museum Wien, Austria (W), (Thiers 2013; http:// E. epithymoides L., together with E. verrucosa L. and E. sweetgum.nybg.org/ih) as well as in the Biology Students flavicoma DC.

Nomenclature used in the Dinaric Alps, mountains of Bosnia and Herzegovina was according to the databases Euro+Med Plantbase (Lubarda 2013), Montenegro (Rohlena 1942) and (http://ww2.bgbm.org/EuroPlusMed/query.asp) or IOPI Serbia (Tomović 2007) as well as in Mts.

It was also recorded in the low-altitude serpentine area of northern Bosnia and RESULTS AND DISCUSSION Herzegovina, together with closely related E. gregersenii K. Malý ex G.
