The family of the Rhamnaceae family was the sixty genra of the almost 300 species that widespread on the tropical and subtropical places. They have few families also on the temperate zone of Holarktisa. There are two groups and 6 genra on the Paliureae and four on the group in northern border from Rhamneae. The violent environment this genra is less resistance to the wind, drought and limestone are to the typical Rhamnuss ss genus. But other type of Rhamnus ss is more resistant to the limestone rock and wind. Those who are largely confined are on the leeward outside of Karst and flysch.
Type of the Rhamnus Cathartic SS
- Rh. Intermedia – this type is the Adriatic coastal at the eastern endemic species that can be found in Istria to Albania. They grow at the thickets of sub-Mediterranean of Paliuro-Petterion.
- Rh. Orbiculata – this type is the endemic one found in coastal forests of Omo-Pinion in Dalmatia, Herzegovina and the Montenegro.
- R. woloscaki – A transitional endemic that crosses between the northern shore type of Rhamnaea. They grow on the strip both on their parents in northern Adriatic Sea and the central Istria.
- Rh. Tinctoria – they grow on the thickets of mountain that expands on the Eastern Europe, such as in Lika, Istria and Herzegovina.
There is a massive widespread of the genera that is isolated and the population grows around European places. These things are documented nearly most of the northern authors. They believed that the boarding genus of Rhamnus is on the water.
