species are mainly components of the Eurasian steppe or steppe-like rocky vegetation, with some taxa occurring also in south-eastern Europe and northern Africa. We analysed the variability ...of: (i) two maternally inherited plastid loci (

K) in 110 individuals of six currently accepted species from the Balkans and one species from the Apennines, to provide new insights into their origin and evolutionary history; and (ii) quantitative morphological characters (14 independent characters and one ratio character) in 641 individuals of three species of which two are morphologically and ecologically similar (
G. italicum
and
G. tataricum
) and the third,
G. dalmaticum
, was frequently misidentified as
G. tataricum
in the past, to provide new taxonomic treatment for proposed
G. tataricum
subspecies. We delineated several quantitative and five qualitative characters studied in a more limited sample as diagnostic for the identification of four subspecies (three newly described and one in a new rank) of
G. tataricum
. The history of westward peripheral populations of this species in the Balkans and the Apennines was rather complex and driven by local geo-historic events. These events facilitated multiple waves of east–west expansion of lineages originating from sources outside of the Balkan Peninsula which periodically diversified and occupied localised areas in the Balkans during the Pleistocene. An initial spread of an ancient
G. tataricum
lineage throughout south-eastern Europe probably occurred during the Messinian Salinity Crisis. Inter- and intraspecific hybridisation/introgression, as well as retention of ancestral polymorphisms, was common in
G. tataricum
and related taxa over time.
The aim of the present study was to assess the metal concentrations in five species of the genus
Viola
L. (section
Melanium
) from 12 ultramafic outcrops and two non-ultramafic (prolluvium and ...dolomite) soils from Serbia and Bosnia and Herzegovina. The concentrations of P

O, Ca, Mg, Fe, Mn, Zn, Cu, Cr, Co, Cd and Pb in soils and plant samples, as well as their shoot-to-root ratio, biological concentration and accumulation factors were determined. Five investigated
Viola
species growing on 14 different localities displayed considerable differences in concentration of potentially toxic elements in their roots and its accumulation in their shoots.
Viola kopaonikensis
and
V. beckiana
from ultramafic soils could be classified as strong Ni accumulators, since moderately high level of Ni was measured in their shoots (up to 266 mg kg
−1
and 337 mg kg
−1
, respectively), while in
V. tricolor
high amount of the same element was accumulated in the roots (up to 395 mg kg
−1
). Population of
V. beckiana
from dolomitic site in Bosnia and Herzegovina accumulated high concentrations of Pb in the shoots (67.1 mg kg
−1
), as well as of Cd in both roots and shoots (81.1 mg kg
−1
and 60.5 mg kg
−1
). The results also suggest that
V. kopaonikensis
populations from the ultramafic soils of Serbia emerge as Cr accumulators, which is quite rare trait within the genus
Viola
. It seems that species from
Melanium
section apply quite different strategies against toxic elements. Future studies should strive to explain what adaptive mechanisms are hidden behind it.
This study surveyed three species of the genus
Armeria
Willd. from five ultramafic outcrops, two non-ultramafic (schist) soils, and one tailing heap of an abandoned iron-copper mine from Serbia. ...Similarities and differences among the three
Armeria
species growing on different geological substrates in the ability to control uptake and translocate nine metals were examined. Chemical characteristics of the soil and plant samples (concentrations of P

K

O, Ca, Fe, Mn, Ni, Zn, Cu, Cr, Co, Cd, and Pb) are presented. In order to assess accumulative potential of these three
Armeria
species, biological concentration, accumulation, as well as translocation factors were used. Three investigated
Armeria
species growing on eight different localities showed large differences in heavy metal uptake, translocation, and accumulation. The differences were present among the plant samples of the same species and even more among three different
Armeria
species and were primarily the result of the different contents of available heavy metals in the investigated soils. Additionally, differences might be the consequence of diverse responses and possible presence of supplementary resistance mechanisms in the plants from the ultramafic soils. None of the three
Armeria
species showed shoot hyperaccumulative potential for any of the investigated heavy metals and they could be considered as root accumulators, considering their potential to accumulate medium to large amounts of Zn (BCF up to 134), Cr (BCF up to 148), and Cd (BCF up to 9) in their roots.

Pontechium maculatum, a facultative metallophyte, was collected from four
ultramafic localities in Serbia and analysed in terms of micro- and
macroelement accumulation. The aim of the study was to ...reveal trace element
profiles and differences in uptake and translocation of heavy metals in
populations growing under heavy metal stress. The concentrations of major
and trace elements in soil samples (Ca, Mg, Fe, Mn, Ni, Pb, Cr, Zn, Cu, Co,
Cd) and in plant tissues (Fe, Mn, Ni, Pb, Cr, Zn, Cu, Co, Cd) are presented.
The results of our analysis indicate that P. maculatum efficiently absorbs
Zn and Cr, while for most of the other elements accumulation levels fit in
the range of values obtained for several other species from ultramafic
localities on the Balkan Peninsula.
