Abstract - Physcomitrium eurystomum Sendtn. and Pohlia proligera (Kindb.) Lindb. ex Broth. were recently discovered as
new moss species for the bryophyte flora of Serbia. Both species were recorded in the Vlasina Lake area, a large highland
wetland plateau in southeastern Serbia.

Introduction
in the Herbarium of the Hungarian Natural History
Museum, Budapest (BP). Our nomenclature follows
Hill et al. (2006).
Even in comparison to other European countries,
Serbia has a rich bryophyte flora containing 118 liverworts (Sabovljević and Natcheva, 2006) and 555
moss species (Sabovljević et al., 2008, 2011). Bryophyte research, however, has received very little attention, and has been a secondary discipline within the botany of the country until the last decade
(Sabovljević et al. 2001; Sabovljević, 2004), when our
work started and resulted in the expansion of known
bryophytes by 25% (hepatics) and 15% (mosses), respectively (Papp et al., 2009).
Study area
Vlasina Lake is situated in southeastern Serbia as part
of the Rhodopian area (Fig. 1). The area is a huge highland plateau surrounded by the peaks Vardenik (1875
m), Čemernik (1638 m), Plana (1721 m) and Bukova
Glava (1472 m). The lake itself is of artificial origin:
between 1949 and 1954 a dam was built by flooding
a major part of the original peat bog, which, by the
way, was the biggest in the Balkans (Randjelović and
Zlatković, 2010). The plateau has an average altitude
above 1200 m (the lake surface is at 1213 m). Geologically, the region is characterized by metamorphic
schists and silicates and many subtypes of these bedrocks; it also has various soil types (Blaženčić, 1997).
The climate of Vlasina is montane-temperate with a
yearly average of 5.7ºC. The hottest month is August
(average 14.7 ºC), and the coldest month is January
(average -4ºC). The mean yearly precipitation is 722.9
mm. During the growing season, the average tem-
Nevertheless, new discoveries are being made
and can be expected at a regular pace, adding continually to the existing bryophyte records of Serbia
(Ellis et al., 2011, 2012; Papp et al., 2012).
Materials and methods
Field trips to the Vlasina Lake and its surroundings
in southeastern Serbia were carried out in June of
2010 and June of 2011. The specimens are preserved

perature is 12.5ºC, and the rainfall is 309.1 mm, with
high averages of air humidity (79-82%). There are
many windy days on the Vlasina plateau, with prevailing western, northern and eastern winds.
The natural biological diversity of the plateau is
marked by various vegetation types including beech
and spruce forests, pine plantations, wetland vegetation, meadows, peat bogs and even some dry pas-
tures and chasmophytic communities. The plateau
with the lake and its surroundings is protected as a
Nature Park.
RESULTS
Physcomitrium eurystomum and Pohlia proligera
were discovered for the first time in Serbia. The collecting data are as follows:

DISCUSSION
Physcomitrium eurystomum is a sub-Mediterranean
species (Düll, 1984) occurring on muddy soil along
streams, margins of lakes with fluctuating water
level (Dierssen, 2001). In Southeast Europe, it is reported only from Bulgaria, Romania and Slovenia
(Sabovljević et al., 2008). Additionally, in the Mediterranean area Ros et al. (in press) cited this species
from Syria, Israel, Italy and France. This species is
quite rare and its occurrence is interesting since it is
taxonomically well defined and reproductively isolated from the other Physcomitrium-Physcomitrella
species complexes. However, McDaniel et al. (2009)
suggest its hybrid origin by assuming an event between two early diverging lineages in the complex,
and that the ancestral population size of these lineages was much smaller than the current population
sizes.
Pohlia proligera is a boreal, montane species
(Düll, 1985) living usually on disturbed open habitats, in rock crevices or on muddy soil mostly on
acidic bedrock (Dierssen, 2001). In southeastern
Europe, it is known only from Bulgaria, Montenegro, Romania and Slovenia (Sabovljević et al., 2008),
while in other places around the Mediterranean it
is apparently present but infrequent (Ros et al., in
press).

This species was sometimes treated as a intraspecific taxon of P. annotina which is known from the
Vlasina (Okruglica) area (Pavletić, 1955). However,
it was not recorded previously in Serbia, neither as
a species nor as an intraspecific taxon. With the new
investigations, P. annotina s. s. was also reported
from the Okruglica site in the Vlasina region.
