SUMMARY: Anthyllis barba-jovis is spread in Croatia in the area presenting
the most xerothermal part of the central and southern Dalmatia (cf. Fig.
I), On the Croatian part of the coast, which is almost completely made of carbonate
rocks, this species generally grows on the carbonates, although inside
its range in the western Mediterranean it is almost completely connected with
the silicate rocks. This being a relatively rare species, there are not many data
on its distribution in Croatia. As this species has specific requirements in
respect to its habitat, namely it cannot stand calcium, its larger distribution in
the Croatian littoral cannot be expected at all, and, therefore, every new finding
of this species is a real rarity.


The research of distribution of this species has not been made so far, and,
therefore, this work is the first review of the so-far status of its distribution in
Croatia. A. barba-jovis is a western Mediterranean species which in our
region has the most eastern boundary of its distribution. Here, it finds a small
number of suitable habitats, so most often it occurs individually or in small
groups, and very rarely it forms larger populations, such as at Komiza on the
island of Vis where it grows on the silicate bed, i.e. on the relict volcanic ash
and fragmented lava. By the latest research, one large population of this
species has been discovered on the small island ofPelinjak and a somewhat
smaller one on the island ofKurba Mala (cf Fig. 1). As said in the introduction,
A. barba-jovis is known also from the island Dugi otok (Grbascak), that
is at the same time its most northern locality on the eastern Adriatic coast (cf.
Fig. 1), and the new locality fill in the earlier gaps in the distribution of this
species in the central Dalmatia.


This being a stenomediterranean species growing on very poor soils
unsuitable for a significant development of forest vegetation, any contribution
to the knowledge of its distribution, in addition to being a valuable natural
science contribution presents also a new knowledge of the vegetation succession
on very xenothermal habitats. As this is a woody species from the family
Fabaceae (leguminous plants), whose species have the capacity to bind the
elementary oxygen from the air, it may be expected that A. barba-jovis will


play a pioneer role and will help considerably in the succession toward the
forest vegetation.
