The vascular flora of Matokit Mt (Biokovo Massif) in southern Croatia was researched in different vegetation periods from 2010-2015, and a total of 604 vascular plant taxa belonging to 86 families and 337 genera were found. The studied area has never been studied in the past and these are the first detailed floristic data about grasslands in different succession stages of Matokit Mt. Collected herbarium specimens (345 sheets) were digitalized and are available at the ZAGR Virtual Herbarium. The most dominant families were legumes (Fabaceae 9.9%), grasses (Poaceae 9.1%), daisies (Asteraceae 7.4%) and mints (Lamiaceae 6.8%). The analysis of life forms shows the dominance of hemicryptophytes (39.9%) and therophytes (26.2%) on Matokit Mt that indicates a high influence of the Mediterranean climate. A total of 36 endangered and 17 invasive plant taxa across the whole studied area were recorded. Endemic are 32 plant taxa (26 endemics in a broader sense and 6 stenoendemics) and they represent new site of Croatian flora. The occurrence of some very rare endemics (Cardamine fialae Fritsch and Erysimum croaticum Polatschek) in the flora of Matokit Mt is of special interest for the national flora.

The campos rupestres form a mosaic of rocky savannas concentrated mainly along the Espinhaço chain, on the Brazilian shield. Though the Serra de São José lies over 100 km to the south of the Espinhaço chain, the campo rupestre flora of this small range harbors several endemic plant taxa. The provided checklist is the result of two decades of floristic research complemented with data from herbaria and literature. The flora is compared with the results of several other pertinent surveys. A total of 1,144 vascular plant species, representing 50.3 species/km2, were documented to date in the São José range, representing a species-richness per unit area over five times greater than other known campo rupestre floras. The most species-rich families were the Asteraceae (126 species), Orchidaceae (106), Melastomataceae (63), Leguminosae (60), Cyperaceae (45), Poaceae (41), Rubiaceae (37), Myrtaceae (28), Bromeliaceae (27), Eriocaulaceae (23), Lamiaceae (23), and Malpighiaceae (22).

We present the first survey of the vascular flora of Scotty Creek, a peatland-dominated watershed with discontinuous permafrost about 60 km south of Fort Simpson, Northwest Territories (NWT). Of the 140 vascular plant taxa found at Scotty Creek, two are additions to the boreal flora of NWT: Arethusa bulbosa (Dragon’s-mouth, Orchidaceae) and Carex pauciflora (Few-flowered Sedge, Cyperaceae). The occurrence of Arethusa bulbosa extends the known range of this species 724 km to the northwest, making this purportedly eastern American plant almost pan-Canadian. Two other major range extensions (> 200 km) are reported for Carex brunnescens subsp. sphaerostachya (Round-spike Brownish Sedge) and Platanthera dilatata var. dilatata (Tall White Bog Orchid). Furthermore, 15 other rare NWT species are reported, including three species known from a single other locality in the NWT. The flora of Scotty Creek is dominated by circumpolar (55%) and widespread North American (34%) elements. Despite the absence of exposed alkaline rocks and the dominance of deep organic soil almost throughout Scotty Creek, a number of limeindicator plants were found in lakes and minerotrophic wetlands.

Field studies in the Hudson Bay Lowland ecoregion of northern Ontario during 2010 resulted in the discovery of four native vascular plant species not previously confirmed from the province: Arctic Bellflower (Campanula uniflora; Campanulaceae), Lapland Diapensia (Diapensia lapponica; Diapensiaceae), Alpine Azalea (Kalmia procumbens; Ericaceae), and Alpine Brook Saxifrage (Saxifraga rivularis; Saxifragaceae). These four species are widespread arctic plants occurring in both North America and Eurasia and were found on the Sutton Ridges, a Precambrian bedrock inlier surrounded by the extensive wetlands of the Hudson Bay Lowland.

Results of non-native flora surveys on Samara Dniprovska River valley within the designed National Park «Samarsky Bir» were analyzed in the paper. Scientific justification on first stage creation of the national-level National Park «Samarsky Bir» was prepared in 2012. Its area included the main park area with floodplain, arena and gully landscapes of the rivers Samara and Oril interstream. List of vascular plant species on floodplain, arena and gully habitats of Prisamar'ya counted 887 species. They are classified as 5 divisions, 6 classes, 108 families, 429 genera. This article presents a list of non-native flora fraction with bioecological characteristic of the plant species. The surveys were conducted by conventional methods on vascular flora studying. Analysis of the main plant ecomorphs was carried out by A. L. Belgard ecomorph system (1950). Invasion of plant species in the steppe zone of Ukraine has a long history complicated by significant anthropogenic transformation of the territory. We investigated the status of non-native plants, their ecomorphs, and tendency to invasiveness on the territory of National Park «Samarsky Bir» designed. Presence of 195 adventitious vascular plant species belonging to 48 families was determined. Of them, 7 families with the greatest abundance of non-native species contained 113 taxa (58 % of the total); 20 families were represented with 2–7 advents, and 20 families contained only 1 non-native species. Thus, today the share of non-native species in the vascular flora of the region accounted for nearly 22 %. Most of adventitious species are mesoxerophytes and xeromesophytes. In a cenomorphic relationship, vegetation being ruderal on the territory of Ukraine is dominated in composition of non-native flora. Within the total number of adventitious species, archaeophytes amount up 44 %, whereas neophytes come up to 56 %. The greatest abundance of adventitious species has been found in Brassicaceae, Asterasea and Poaceae families (15 %, 12 %, and 11 % of the total, respectively). 119 non-native vascular plant species were found in the steppe cenoses, 79 species in the gully and watershed forests, 90 species in floodplain forests, and 52 species on the territory of the sandy terrace. Among all the non-native species, 28 species have been identified as invasive, and there was a trend to increased invasiveness of some species in recent years. Among heterogenous species 12 of them were identified as invasive, and there was a tendency to increase theinvasiveness of some species in recent years. The analysis provided on non-native flora in the National Park evidences significant anthropogenic transformation of the territory; that requires establishment of appropriate regime on protection of this important ecological object.

Cape Prince of Wales on the western tip of the Seward Peninsula in Alaska is the closest point in continental North America to Asia. From here the eastern tip of the Chukotsk Peninsula is less than 80 km away across the Bering Strait. Owing to the position of the Seward Peninsula, its flora is of great biogeographic interest, yet until recently was poorly known because of the remoteness of the region. Here I document the 292 vascular plant taxa that compose the flora at Cape Prince of Wales. I consider this Bering Strait region a distinct phytogeographic zone. The flora has strong alpine affinities, and it is marked by the local abundance of certain Asiatic and Beringian species, and the absence of continental species requiring summer warmth that are common elsewhere on the Seward Peninsula.

The vascular flora identified in 1968–1969 in three rice fields of the Winyah Bay Estuary at the Bell W. Baruch Institute for Marine Biology and Coastal Research, Georgetown County, South Carolina, abandoned in 1915, was compared with the vascular flora present in 1987–1991 and 2013–2015. Twenty vascular plant species were identified in 1968–1969 and 22 in 2013–2015 at the most saline marsh, Thousand Acre Rice Field. Forty-seven taxa were reported at Airport Marsh in 1968–1969 and 27 in 2013–2015. Fifty-six taxa were reported at Alderly in 1968–1969 with 41 identified there in 2013–2015. A parsimony algorithm was used to evaluate the distribution and co-occurrence of vascular brackish marsh species in these fields sampled at the three intervals. There was a reduction in flora at the two least saline sites, Alderly and Airport Marsh, from 1968–69 to 1987–91 and 2013–2015. Three factors—rising sea level, an increase in water salinity, and invasion by Phragmites australis—may explain this shift. There was also a shift in the flora at Thousand Acre Rice Field from 1967–1969 to 1987–1991 and 2013–2015 after the marsh was savaged by Hurricane Hugo in 1989. Invasion by non-native Phragmites australis at all sites and increase in water salinity at all sites best explain the reduction in vascular plant species at Airport Marsh and Alderly over the 47-year collection period.

Abstract Published data on the vascular flora of Erath County, Texas, is limited. In this investigation, data were obtained from vascular plant specimens deposited in the Tarleton State University Herbarium (TAC). Sixty-six new county records were recorded for Erath County. Major range extensions were documented for forty species, these having previously been known from at least one county away distant from the border of Erath County. Fourteen of the species are non-native while 52 species are native; only one of these, Yucca rupicola Scheele (Texas yucca), is endemic to Texas. No rare, threatened, endangered or state-listed noxious species were found.

Relics of cultivation in the vascular flora of medieval West Slavic settlements and castlesThis monograph presents results of research on relics of cultivation and the present vascular flora of sites of medieval fortified settlements and castles in Central Europe. Special attention was paid to 109 West Slavic sites located in Poland, northeastern Germany, and the Czech Republic. For comparison, floristic data were collected also at 21 sites of medieval settlements and castles of Baltic tribes, East Slavs, and Teutonic knights. Results of this study confirm the hypothesis that remnants of medieval fortified settlements and castles are valuable habitat islands in the agricultural landscape, and are refuges of the plants that have accompanied West Slavs since the Middle Ages. At the 109 West Slavic archaeological sites, 876 vascular plant species were recorded. The present flora of the study sites is highly specific, clearly distinct from the surrounding natural environment, as shown by results of analyses of taxonomic composition, geographical-historical and synecological groups, indices of anthropogenic changes of the flora, and degrees of hemeroby (i.e. human influence) at the studied habitats. The sites of fortified settlements and castles are centres of concentration and sources of dispersal of alien species. Aliens account for nearly 21% of the vascular flora of the study sites. Among them, a major role is played by archaeophytes (101 species). Some archaeological sites are characterized by a high contribution of so-called species of old deciduous forests (98 species). Despite many features in common, floras of archaeological sites vary significantly, depending on their geographical location, size, typology, and chronology of their origin. Historical sites occupied in the past by West Slavs differ in the current vascular flora from the sites occupied in the Middle Ages by East Slavs or Baltic tribes and from Teutonic castles. West Slavic archaeological sites are primarily refuges for 22 relics of cultivation. Considering the time of cultivation, 3 groups of relics were distinguished: (i) relics of medieval cultivation (plants cultivated till the late 15thcentury); (ii) relics of cultivation in the modern era (introduced into cultivation in the 16thcentury or later), and (iii) relics of medieval-modern cultivation. These species play a special role in research on the history of the flora of Central Europe and thus also of the world flora. Thus the best-preserved sites of medieval West Slavic settlements and castles should be protected as our both cultural and natural heritage. This work is a key contribution to geobotanical research on transformation of the vegetation associated with human activity. Considering the problem of relics of cultivation it corresponds also to basic ethnobotanical issues.
