We present new data concerning lichen species of the Italian flora and confirm 36 national redlisted species.
Typhetum laxmannii (Ubrizsy 1961) Nedelcu 1968 - The new plant association in Poland
2011
<em>Typhetum laxmannii</em> (Ubrizsy 1961) Nedelcu 1968 is a plant association new to Poland, built by an expansive kenophyte - <em>Typha laxmannii</em> Lepech. This paper presents the general distribution of both, the species and the association, paying particular attention to the area of Europe and Poland where, in recent years, many new locations as well as an increasing participation in vegetation cover have been observed. The habitat preferences of <em>Typhetum laxmannii</em>, the floristic composition of the association and its geographical differentiation within the occupied area are described. The current distribution of the association in Poland …
The floristic research in Italian archaeological sites
2018
In Italy occur about 240 archaeological areas or parks and more than 1500 main monumental complexes; the number of individual monuments would exceed several thousand. The interest on the flora of archaeological sites in Italy dates back to the XVII Century. The scope of floristic inventories can be limited to the mere list of the plants growing into the area or this list can be accompanied by indication of the dangerousness for the monument represented by single species and the indications for their management. For this review the basic references concerning the flora of archaeological sites located in Italy were listed and classified by publication date, area, and main historical period or…
On the presence of Orthotrichum shawii (Orthotrichaceae) in California
2006
Study of the material on which E. G. Britton based the report of Orthotrichum shawii from California confirms this overlooked report. Diagnostic characters of the species are presented, and the differences between the known American specimen and those from Europe and Africa, are discussed. Finally, the differences between this species and those with which it has been confused are discussed.
A revision of Tamarix specimens (Tamaricaceae) kept in the BCN herbarium of Barcelona (Spain)
2018
The taxonomy of genus Tamarix L. is notoriously controversial and many taxa are still not or wrongly identified. A huge number of tamarisk specimens are kept in the most important herbaria of Spanish universities but many labels needs a deep nomenclatural revision. The Tamarix collection in Universitat de Barcelona (BCN) is composed by 158 samples, collected in different Comunidades Autónomas de España, and corresponding to 14 taxa.
Reliability and effectiveness of Ellenberg’s indices in checking flora and vegetation changes induced by climatic variations
2001
Two methods are proposed to assess the significance of time-spanned local variations of Ellenberg’s indicator values in floristic and phytosociological data sets respectively. Both methods are based on frequencies and averages of the indicator values within and among data sets. Main goal of proposed methods is to determine the threshold above which the observed variations are to be considered significant. In order to relate the observed floristic variations to recent climatic changes, attention was focused on the Ellenberg’s indices dealing with the main climatic variables: heliophany, temperature and precipitation. Study-cases from Zannone Island (Pontine Archipelago, Mediterranean region)…
