Abstract
In this work the central part of the Dinaric mountain chain is considered, i. e. the mountain massif of the Dinara, Troglav and Kamešnica, with the highest level at Troglav (1913 m). The study is restricted to the mountain (alpine) associations within climatic region of the distribution of Pinus mugo and submountainous Fagus sylvatica forests (Table 1). Among these alpine communities subalpine and alpine plants are considered and also some taxa of larger vertical spread which take important part in building up this alpine vegetation.
The work treats the geographic flora element, i. e. the flora is classified according to the geographic spread of plants — with the aim to make the basis for determining all other types of flora elements and also to be the basis for the hypotheses on the origin and history of the development of plants. Using the geographic-systematic method selected members of the mountain flora of the Dinara, Troglav and Kamešnica have been examined in detail as regards their most important synonyms and geographic distribution, ecology of habitat and phytocenological connection and phylogenetic relations and their variability (Volarić-Mršić 1972). On the ground of the data obtained, and particularly on the ground of geographic spread i. e. the area of distribution of single plants the author has been able to establish and treat the following flora geoelements (table 2—7): Arcto-alpine (17 species, or 10,7%), 2. Altaic-alpine (5 species, 3,1%), 3. Central European mountainous (48 taxa, 28,3%), 4. Mediterranean mountainous (7 species, 4,4%), 5. South European mountainous (11 species, 6,9%), and 6. Southeast European mountainous (106 taxa, 52,2%). Figural relation of single geoelements is shown in table 9 and Fig. 1 and the relation of seven groups of South-eastern European mountainous geoelement is shown in Fig. 2. From the Southeast European mountain (alpine) geoelement the author has separated and defined a new, Dinaric geoelement (tab. 8) including 51 taxa.
