According to the Croatian Red List (Nikolić 2019b) a total of 36 taxa were found (Tab. 3). Two species (Papaver argemone and Consolida ajacis) are Critically Endangered (CR), one species (Hibiscus trionum) is Endangered (EN), while five species are classified as Vulnerable (VU). From the other IUCN categories, 16 taxa have been classified as Nearly Threatened (NT), 6 are of Least Concern (LC) and 6 were found to be Data Deficient (DD). Seventeen invasive and 32 endemic vascular plant taxa were recorded, of which 26 endemics in a broader sense and 6 stenoendemics (Tab. 3, Fig. 3).
The vascular flora of Matokit Mt was studied for the first time systematically and here is presented the first comprehensive floristic list of 604 vascular plant taxa, of different habitats, mostly grasslands in succession, rocky crevices and forest fringes, as well as a short overview on some interesting taxa in the flora Matokit Mt as a part of Biokovo massif. Floristic richness of the studied area is high, in comparison to several Croatian mountains along the eastern Adriatic coast especially considering the size of the area (Nikolić et al. 2008). The number of recorded plant taxa in comparison with similar floristic researches of the Dalmatian littoral mountains is quite similar. According to Kamenjarin (1996) in the flora of Kozjak Mt above Split 604 plant taxa were recorded, about 600 taxa were recorded in the flora of Mosor Mt (Bedalov and Šegulja 1987; Vladović and Ilijanić 1992, 1993, 1995). For Biokovo Mt the number of more than 1400 recorded taxa is result of more intensive and detailed floristic studies performed in the past (Hršak and Alegro 2008).
The occurrence of families Fabaceae (9.9%), Poaceae (9.1%), Asteraceae (7.4%) and Lamiaceae (6.8%) in the flora of Matokit Mt is quite normally distributed according to Nikolić (2001). The domination of hemicryptophytes (39.9%) and therophytes (26.2%) in the flora of Matokit Mt, as well as moderate present of geophytes (12.4%), phanerophytes and chamaephytes (10.8%) indicates high influence of the Mediterranean climate according to Horvat (1949).
In the flora of Matokit Mt a total of 32 endemic taxa were found (Tab. 3). Majority of endemic taxa were found within the vegetation of Natura 2000 grasslands and pastures in different succession stages e.g. a combination of rocky pastures of Chrysopogono grylli-Saturejion subspicatae Horvat & Horvatić ex Černjavski, Grebenščikov & Pavlović 1949 and grasslands of Saturejion subspicatae Tomić-Stanković 1970, as well as within chasmophytic vegetation of the Centaureo cuspidatae-Portenschlagiellion ramosissimae Trinajstić ex Terzi et Di Pietro 2016. Especially interesting for the Croatian flora are the findings of recently recorded Cardamine fialae in the flora of Matokit Mt (Vukojević et al. 2016). The species grows on lower altitudes in rocky ground within the vegetation of forest fringes and secondary also in ruderal places, in arable fields, on shady screes and very rarely in rock crevices (Vukojević et al. 2016). All new localities in Croatia are close to Klobuk (locus classicus) in Bosnia and Herzegovina. Another Balkan endemic taxon, Erysimum croaticum, recently described by Polatschek (2013) from Zadvarje in Croatia was found in the flora of Matokit Mt there were a few individuals on screes of southern slopes. According to Polatschek (2013) this species is distributed in West Kosovo and Dalmatia (Mosor, Omiš, Brela region, Zadvarje and Makarska) and the new locality on Matokit Mt within Biokovo massif contributes to a better understanding of species distribution.
A spontaneous hybridogenic Iris population, evidently hybrid between I. illyrica and I. pseudopallida was recorded. Several populations with a few individuals growing within rocky grassland at higher altitudes (approximately 900-1000 m a.s.l.) were found. In the Flora Croatica Database (Nikolić 2019a) this taxon is not listed, and the occurrence of this Iris hybrid is not surprising because Matokit Mt represents the overlapping distribution area of I. illyrica and I. pseudopallida, and it could be found anywhere along the Adriatic littoral where parental species occur. Although those hybrids are known from literature in Croatian flora (Mitić et al. 2000, 2001, 2013; Biljaković 2002) taxonomical status of this hybrid is questionable and was not a subject of this research.
Some narrowly distributed species of the Croatian flora were also found in the flora of Matokit Mt e.g. Thymus bracteosus and Linaria microsepala. For endemic taxon Vicia ochroleuca ssp. dinara, the Matokit Mt represents the
