SUMMARY The vascular flora of Matokit Mt (Biokovo Massif) in southern Croatia was researched in different vegetation periods from 2010-2015, and a total of 604 vascular plant taxa belonging to 86 families and 337 genera were found. The studied area has never been studied in the past and these are the first detailed floristic data about grasslands in different succession stages of Matokit Mt. Collected herbarium specimens (345 sheets) were digitalized and are available at the ZAGR Virtual Herbarium. The most dominant families were legumes (Fabaceae 9.9%), grasses (Poaceae 9.1%), daisies (Asteraceae 7.4%) and mints (Lamiaceae 6.8%). The analysis of life forms shows the dominance of hemicryptophytes (39.9%) and therophytes (26.2%) on Matokit Mt that indicates a high influence of the Mediterranean climate. A total of 36 endangered and 17 invasive plant taxa across the whole studied area were recorded. Endemic are 32 plant taxa (26 endemics in a broader sense and 6 stenoendemics) and they represent new site of Croatian flora. The occurrence of some very rare endemics (Cardamine fialae Fritsch and Erysimum croaticum Polatschek) in the flora of Matokit Mt is of special interest for the national flora.

INTRODUCTION
UVOD
The Dinaric mountain range is the lower chained highland mountain of Southeastern Europe, representing the largest karst area that is known for its extremely high plant richness and biodiversity. The highest mountains in the Croatian Dinarides are Velebit, Dinara and Biokovo Massif. Within Biokovo Massif, Matokit Mt (lat. Monte Acutum, translated “the sharp Mountain”) is the mountain ridge located in the surrounding of the town of Vrgorac in Dalmatian hinterland, and represents a wider area of the Biokovo Massif (Fig. 1). Matokit Mt provides the dinaric northwest-southeast direction with the highest peak (Sv. Rok) at 1062 m a.s.l. and total length of approximately 8.5 km (Vukosav 2006; Vukojević 2011).
Matokit Mt is situated in southern Croatia, next to the Vrgorac Town (Fig. 1). The eastern side of the Matokit Mt has relatively steep slopes, while the western slopes are easily accessible. The climate is a sub-Mediterranean with a great influence of continental climate, with an average annual temperature of 14.3°C (lower than the average of typical Mediterranean climate) and 1720 mm of average annual rainfall measured by National Hydrometeorological Institute from 1981 to 2010 for the Town Vrgorac). The duration of snow cover is short at a lower altitude, but in higher altitudinal
