In the present paper the Dalmatian Pine woods (Pinus nigra A r n. subsp. dalmatica Vis. s. 1.) were investigated in regard to their geographical distribution, floristical compound and phytocoenological appertai- nence in the area of the mountain Biokovo, where they were till now thoroughly unexamined.
The Dalmatian Pine woods are limited in their horizontal distribution to the noth-western part of Biokovo showing a decidedly relict character. The consociations are mostly developed in the districts: Borovac, Borovik, Bukovac, Pakline and Nevistina stijena (see the geographic map nearly). As to the vertical distribution there is a higher zone lying in the height of 1100—1500 m above the sea level to which the woods on Borovac, Borovik and Bukovac are belonging (see profil I), and a lower zone with a height of about 500—900 m above the sea level the woods of which are distributed in Pakline and Nevistina stijena (see profil II). The woods of the higher zone are situated between the submediterranean area and the maritime beechwood area (in the stony ground vegetation area i. e. Seslerio-Juniperetum sibiricae), while the woods of the lower zone are located thoroughly inside the area of the submediterranean climax wood Seslerio-Ostryetum carpinifoliae. In regard to the phytocoenological appertainence there is stated on the basis of a greater number of phytocoenological records, that we may consider the woods of the higher zone as a separate subassotiation of a typical community of stony ground vegetation areas, with which their are very relative; therefore the name Seslerio-Juniperetum sibiricae pinetosum dalmaticae Domac is used for them, because even the stony ground vegetation areas are treated here for the first time under the name Seslerio-Juniperetum sibiricae (Horvat) Domac (see table I).
Besides the Dalmatian Pine the most characteristic plants of these communities are Juniperus sibirica and Sesleria robusta (S. nitida). The structure and the composition of these woods are shown in details on the table II.
For the woods of the lower zone it has been shown that they represent in accordance with the earlier expressed concept of Horvatic (1958:83) only a facies of the submediterranean climax — wood Seslerio- Ostryetum carpinifoliae and are therefore comprehended under the term Seslerio-Ostryetum pinosum dalmaticae Horvatic. Their composition and structure are shown on the table III.
The Dalmatian Pine woods on Biokovo develop as well in the higher as in the lower zone on pure limestone.
