During a century of research, new species have been described, and theoriginally infraspecific statuses of many of Hackel’s taxa have been raised to specieslevel. As a result of this process, the number of recognised species has increasedfrom 28 (HACKEL, 1882) to 170 (MARKGRAF-DANNENBERG, 1980).NAT. CROAT. VOL. 15 No 4 237–242 ZAGREB December 31, 2006Croatian Natural History Museum, Demetrova 1, Zagreb, Croatia238 Alegro, A.: Festuca hercegovinica Markgr.-Dannenb. (Poaceae) in the flora of CroatiaFig. 1. Festuca hercegovinica: a) panicle; b) spikelet; c) leaf cross sectionOne of these recently described species is Festuca hercegovinica Markgr.-Dannenb.1978, a little-known species not included in the Index Florae Croaticae (ILIJANI] &TOPI], 2000). The species belongs to subgen. Festuca sect. Festuca, a group characte-rised by thick leaves with a continuous ring of sclerenchyma and mostly sevennerves on the cross section. According to HACKEL’s Monograph (1882: 83, 89–90) itcould be treated as a member of F. duriuscula (F. ovina L. subsp. euovina var. durius-cula Hack.) organisation type. Consequently, LAKU[I] (1999) included it in the F.duriuscula complex. However, the name F. duriuscula is a nomen ambiguum (cf. MARK-GRAF-DANNENBERG, 1976) and therefore inappropriate for naming taxa; nevertheless,it can remain in use for the informal naming of group or aggregate. According toKOSTADINOVSKI (1999) F. hercegovinica is closely related to the species F. hirtovaginata(Acht.) Markgr.-Dannenb. as will be discussed later. Some other related speciesfrom the Balkan region are F. thracica (Acht.) Markgr.-Dannenb., F. grandiaristataMarkgr.-Dannenb., F. macedonica Vetter, F. koritnicensis Vetter in Hayek and F. polita(Halácsy) Tzvelev.The type specimen originates from Herzegovina (Republic of Bosnia and Herze-govina), between Uskoplje and Ivanica. As well as this this locus classicus MARK-GRAF-DANNENBERG (1978) quoted some other localities of the species in Herzegovina,the southernmost parts of Croatia (the surroundings of Dubrovnik: O{tra Glavica,Gru`, Ombla valley), the Republic of Macedonia (SE from Ohrid) and Greek Mace-donia (mountains above Pisoderion). Later, the species was found also in Monte-negro (Mt Durmitor: in the Su{ica canyon) by LAKU[I] (1999), and in several morelocalities in Macedonia (predominantly in the western parts) by KOSTADINOVSKI(1999).Conclusively, it can be stated that, according to the present state of knowledge,the species F. hercegovinica is an endemic species of the Balkans, distributed fromNorthern Greece, through Macedonia, southern Montenegro and the southernmostparts of Croatia to south-eastern Herzegovina.The main purpose of this paper is to contribute to the knowledge of the choro-logy of F. hercegovina by recent field observation. Because of the observed variabilityand of difficulties in determination, a key has been prepared.RESULTS AND DISCUSSIONDuring field work in Konavle region (May, 2004), F. hercegovinica (Fig. 1) wasfound as a common species on calcareous, rocky, open habitats, distributed fromthe lowland almost to the top of the Mt Snije`nica (1234 m a.s.l.). Furthermore,additional revision of herbarium collections (ZA) showed that it is present even onthe island of [ipan (the Elaphitic archipelago). The known distribution in Croatia ispresented in Fig. 2.Comparing the descriptions of the species F. hercegovinica and F. hirtovaginata (cf.MARKGRAF-DANNENBERG, 1980) it is difficult to find substantial differences betweenthem. Furthermore, they are sympatric taxa sharing similar habitats. The species canbe recognized only by the hairiness and openness of the sheaths and partially byNat. Croat. Vol. 15(4), 2006 239the lemma dimensions. F. hercegovinica should have glabrous sheaths closed in thelower quarter, and the lemmas 6.2–7.5 × 2.1–2.5 mm; and the species F. hirtovaginatasheaths with dense, patent hairs, open nearly to the base, and lemmas 5.4–7.1 ×1.8–2.2 mm. KOSTADINOVSKI (1999) investigated the range of variability of morpholo-gical characters of these species and came to the conclusion that it is much greaterthan presented by MARKGRAF-DANNENBERG (1978, 1980). Accordingly, he proposeda new taxonomical treatment of these taxa, separating them at the varietal level: F.hirtovaginata (Acht.) Markgr.-Dannenb. var. hirtovaginata and F. hirtovaginata var. her-cegovinica (Markgr.-Dannenb.) Kostadinovski (this comb. nova has not been pub-lished validly previously and has to be considered as nom. illeg.). He also came tothe conclusion that F. hirtovaginata var. hirtovaginata can have a larger number ofveins and ribs on the leaf cross section.All collected specimens from Croatia had glabrous sheaths, but mostly opennearly to the base, and seven veins on the leaf cross section. This combination ofcharacters also supports Kostadinovski’s point of view.For a final solution of the classification of these taxa further study is needed inwhole range of their distribution.Without regard to its taxonomical level, the existence of a well distinguishabletaxon within the flora of Croatia is clear, and the differential characteristics withrespect to the other Croatian species (except F. hirtovaginata which is not member ofthe Croatian flora) are presented in the determination key. F. hirtovaginata and F.hercegovinica are presented at the specific level, but previous discussion has to beconsidered.240 Alegro, A.: Festuca hercegovinica Markgr.-Dannenb.
