Contribution to the flora of Asian and European countries: new national and regional vascular plant records, 7
New records for 29 vascular plant species from 12 Eurasian countries are presented, with synonyms, general distribution, habitat preferences, taxonomy with remarks on recognition, and differentiation the species from the most similar taxa occurring in a given country.
Carex flava agg. (section Ceratocystis, Cyperaceae) in Poland: taxonomy, morphological variation, and soil conditions
Abstract Sedges of Carex flava agg., typical of moist or wet habitats, are difficult to classify because of a lack of clear-cut morphological differences between them and the existence of numerous
Carex section Racemosae (Cyperaceae) in Europe: morphological diversity, taxonomy and phylogenetic relationships
The results show that C. bicolor differs from other taxa in section Racemosae in macro- and micromorphological characters, justifying removal of the species from the section and reconsidering the position of this species in subsection Alpinae.
Morphological variation of Platanthera chlorantha (Orchidaceae) in forest sites of NW Poland
The aim of this study was to check a hypothesis on the morphological variability of the Platanthera chlorantha growing in forests in the north-west of Poland (Dobrzany and Karnieszewice Forestries).
Chromosome numbers of Carex (Cyperaceae) and their taxonomic implications
The results of this study indicate that the position of C. cilicica in Aulocystis section may raise doubts, and attention was paid to the relationship between C. phyllostachys and taxa of the subgenus Carex section Gynobasidae.
Natural Hybridization within the Carex flava Complex (Cyperaceae) in Poland: Morphometric Studies
The morphological characters most useful in distinguishing between hybrids and their parental species in the C. flava aggregate are the size of the utricle and the beak as well as characters transgressive in the hybrids, associated with inflorescence length, location of female spikes, and length of male utricles and their peduncles.
Numerical analysis of morphology of natural hybrids between Carex hostiana and the members of Carex flava agg. (Cyperaceae)
The least variable traits, namelyBeak length, utricle length, ratio of beak length to the overall utrics, female spike width, and width of the lowest bract, proved to be the most useful in delimiting the hybrids.
Habitat Requirements of Marsh Dandelions (Taraxacum) in Polish and Estonian Coastal Grasslands
ABSTRACT Factors determining the distribution of highly endangered marsh dandelion species in Polish and Estonian coastal grasslands have been investigated. The aim of this study was twofold: (i) to
Carex phyllostachys (Cyperaceae), a new species in Croatia
The occurrence of Carex phyllostachys (Cyperaceae) in the Croatian flora is documented here for the first time, and morphological similarities with allied species (C. distachya and C. illegitima) are discussed.
Within-species variation among populations of the Carex flava complex as a function of habitat conditions
Phenotypic variability in the species of the C. flava complex is related to habitat conditions and this can lead to the differentiation of morphotypes within species, as well as to habitat fertility, elevation and habitat disturbance.
