For the purpose of the present study we considered as Italian endemics those specific and subspecific taxa occurring in Italy that are not found elsewhere with the exception of Corsica (France) and Malta. This study presents an updated list of the endemic taxa in the Italian flora, including their geographical distribution at regional level. Italy is characterized by 1371 endemic species and subspecies (18.9% of the total vascular flora): three taxa belong to Lycopodiidae, one to Polypodiidae, two to Pinidae and 1365 to Magnoliidae (three paleoherbs, 221 monocots and 1144 eudicots). The endemic flora belongs to 29 orders, 67 families and 304 genera. Sicily, Sardinia, Calabria and Abruzzo are the four regions richest in endemics. About 58% of endemics are confined to a single administrative region. The most represented orders, families and genera are: Asterales, Caryophyllales and Asparagales, Asteraceae, Plumbaginaceae and Caryophyllaceae, Limonium, Centaurea and Hieracium, respectively. The phytogeographic isolation of Sardinia and Sicily and the separation of peninsular Italy from Northern Italy is confirmed. The relative isolation of Puglia with respect the remaining southern Italian pensinsular regions is also confirmed. Alpine region endemics (from northern Italy) are underrepresented.

<p><strong>Background: </strong>The Campanulaceae are a medium size family of flowering plants in the Dicotyledons, which is well represented in most of Mexico.</p><p><strong>Question: </strong>¿How advanced is the knowledge of the diversity, adequate taxonomic resolution and geographical distribution of a group of vascular plants of lesser economic and ecological relevance?</p><p><strong>Studied taxa: </strong>Members of the family Campanulaceae Juss.</p><p><strong>Studied site: </strong>Territory of the Republic of Mexico.</p><p><strong>Methods:</strong> The revision of herbarium specimens with the aid of information found in literature and internet allowed the integration of a catalogue of known members of the family and of their updated names. The obtained list was then subjected to a brief quantitave and phytogeographic analysis.</p><p><strong>Results: </strong>A list of 117 at least tentatively accepted species is provided together with data on known geographical distribution and brief additional information for each one. The state of Oaxaca proved to be the best represented area with 38 species, eight of which, as well as one genus (<em>Wimmeranthus</em>), are endemic to the state territory.</p><strong>Conclusions: </strong>The study shows that the inclusive knowledge of the group still requires the discovery and description of a significant number of species, as well as a particular effort to clarify the correct taxonomic situation of several members of the family.

The aim of the study was to present “Herbarium” computer database. The basic goal of construction of the database was gathering and analysing of archival and contemporary floristic data referring to the area of Central Poland. Registered information considers the stands and characteristic biological and ecological traits of particular taxa. Life forms, indices of ecological requirements, the phytogeographical elements, protection and threat status are among them. The database enables the presentation of geographical distribution of taxa in the area of Central Poland with the cartogram method based on the grid of 2 km2 according to the Distribution Atlas of Vascular Plants in Poland (ATPOL).

After many recent findings regarding geographical distribution and nomenclatural changes, an updated and revised checklist of the Egyptian endemic flora was needed. This study provides an up to date checklist of vascular taxa exclusive to Egypt and their distribution within the administrative provinces. Egypt hosts 48 endemic taxa (including 35 species, seven subspecies and six varieties) belonging to 42 genera, 18 families and representing 2.3% of the total flora. The most represented families are Asteraceae, Lamiaceae, Caryophyllaceae, Fabaceae, Asparagaceae and Brassicaceae, while the most represented genus is Silene (three endemic taxa). Therophytes and chamaephytes are the most represented life-forms among Egyptian endemics. The richest regions in Egyptian endemic taxa are Southern Sinai (14 taxa), Northern Sinai and Matrouh (12 taxa each). Agglomerative hierarchical clustering (AHC) enabled the division of Egypt into three main regions based on the occurrence of endemic taxa: Eastern Egypt (31 taxa, 25 exclusive and six shared taxa), Western Egypt (14 taxa, seven exclusive and seven shared taxa) and Middle Egypt (12 taxa, eight exclusive and four shared taxa). This checklist will help to focus conservation efforts and provide a framework for research, protection and policy implementations for these endemic taxa.

Abstract The Flora of North America north of Mexico treats all native and naturalized vascular plants and bryophytes in Canada, Greenland, St. Pierre et Miquelon, and the continental United States including the Florida Keys and Aleutian Islands (approximately 18 million square kilometers). It provides accepted names, literature citations, basionyms, synonyms, morphological descriptions, habitat, geographical distribution, conservation or weed status, and a discussion of taxonomic issues for approximately 20,000 species. Of the total 30 volumes anticipated, 18 have been published and one is in press, treating 2021 genera and 12,393 species. For the remaining volumes, 763 genera and 5,008 species have been submitted, and 82 of the 144 families have been submitted in full. Completion is anticipated by the end of 2017. The project is managed by the Flora of North America Association. Content from published volumes is available through eFloras and JSTOR and has been provided to the World Flora informatics team.
