ABSTRACT: The phylogentic position of the Campanula trichocalycina-pichleri complex, a group consisting of two species distributed respectively in the Apeninenes and the Balkans, represents a long-standing taxonomic problem resulting from a conflict among limited number of morphological characters. Traditionally, this complex was treated either as a separate genus, Podanthum, or as part of Campanula or Asyneuma. However, these competing taxonomic hypotheses have never been tested using explicite phylogenetic approaches. We present here the results of molecular phylogenetic analyses based on non-coding chloroplast sequences (trnL-F). Molecular evidence indicates that Campanula trichocalycina and C. pichleri form a strongly supported lineage, positioned as sistergroup to Asyneuma s.str. Consequently, we treate this complex as congeneric with Asyneuma. We also discuss relative importance of floral morphology versus fruit dehiscence for circumscription of Asyneuma and Campanula as well as proposed taxonomic status of Asyneuma comosiforme, a species recently discovered not to be closely related to other members of Asyneuma and segregated from this genus.

ABSTRACT: This paper presents six plant species rediscovered for flora of Serbia after they were considered extinct in this territory. Therefore they were included in the publication “Red Book of Flora of Serbia 1” in the category of Extinct taxon (EX). These six species are: Aconitum anthora L., Aldrovanda vesiculosa L., Chorispora tenella (Pallas) DC., Dracocephalum ruyschiana L., Juncus capitatus Weigel and Linum nodiflorum L. According to new IUCN criteria, the threat status estimation were made and the species were placed in the group of critically endangered within the territory of Serbia. New field observations of population stage and data of distribution are presented for 21 plants that were included in the category of critically endangered taxa in this publication. Population size of plants on the studied localities and new threatened status were presented for each taxon.

ABSTRACT: This article presents the distribution of two Leucojum ispecies (L. aestivum and L. vernum) in Serbia, on the basis of field research, herbarium and literature data. The distribution, ecological preferences as well as threatened status of the Leucojum species in Serbia is estimated according to 2001 IUCN Red list categories and criteria and should provide useful information for conservation management of these species in SE Europe.

KEY WORDS: Leucojum, distribution, ecology, threatened status, Serbia

ABSTRACT: A detail description of the total variability of the characters of the leaf anatomy in different populations of taxon S. rigida sensu lato on the territory of Serbia was made. Morphometric analyses were performed on the cross-section of 521 tiller leaves collected from 21 populations of S. rigida in Serbia. Statistical data analyses were calculated for 27 morphometric characters. Descriptive statistics (mean, standard deviation, minimum, maximum and standard error, coefficient of variation) were calculated for each character state and correlative variability and variations in regard to the geographical gradients was performed to identify the trends in anatomical differentiation. Analysis of variance (ANOVA) was performed to identify significant variation between each character.
A detail analysis has shown that local populations are anatomically very well differentiated into the serpentine populations from western and carbonate populations from eastern Serbia.

ABSTRACT: Phytosociological characteristics of chasmophitic communities on subalpine serpentine cliff s of Kopaonik Mountain were analysed according to Braun-Blanquet methodology. In order to detect purely fl oristic diff erentiation of analysed communities we applied ordinary Correspondence Analysis (CA). Relationship between vegetation and environment was assessed using the Canonical Correspondence Analysis (CCA), while classifi cation of sites was performed using UPGMA method and chord distance. All analyses were performed using the latest version of the “FLORA” package. According to fl oristic and ecological characteristics, analysed chasmophitic communities on serpentine cliff s of Kopaonik Mountain is divided in three new associations: Edraiantho jugoslavici- Festucetum pancicianae ass. nova, Silenetum serbicae ass. nova and Musco-Jovibarbetum kopaonikense ass. nova.
