The relative abundance and ecology of 123 lichens, 12 liverworts, 1 peat moss, 59 mosses, and 40 vascular plants are described from the southeastern part of Prince Patrick Island, 76° N latitude. One hundred and three of the lichens, 25 of the bryophytes, and 6 of the vascular plants are first reports for the island. One lichen, Blastenia arctica, is reported for the first time from North America. One hundred and seventy of the species were found on the ground, 51 on rock, 9 on decaying plant material, 9 on bone, 5 on fossil wood, 4 on caribou dung, and 2 on mosses. Sixteen habitat types are described, based upon a relevé analysis of 31 different sites. A percentage of the lichens (95.1%), of the bryophytes (95.8%), and of the vascular plants (60.0%) encountered have a Circumpolar distribution. A percentage of the lichens (3.3%), of the bryophytes (1.4%), of the vascular plants (22.5%) have an American distribution. Eight species have an Amphi-Beringian distribution: lichens, 1.6%; bryophytes, 1.4%; vascular plants, 12.5%. One bryophyte (1.4%) and two vascular plants (5.0%) have an Amphi-Atlantic distribution.

New collections of vascular plants, bryophytes, lichen, and algae are reported for Cunningham Inlet on the north coast of Somerset Island, Nunavut. This list of 48 species of vascular plants, 13 bryophytes, 10 lichens, and five algae includes 136 specimens collected in 2013 and 39 previously unreported specimens from the National Herbarium of Canada at the Canadian Museum of Nature (CAN), Agriculture and Agri-Food Canada’s Vascular Plant Herbarium (DAO), and University of Alberta (ALTA). Ten vascular plants from previous collecting in 1958 are re-reported here to give a comprehensive account of the vascular plant flora of the region. Two vascular plants are recorded for the first time for Somerset Island: Smooth Draba (Draba glabella Pursh) and Edlund’s Fescue (Festuca edlundiae S. G. Aiken, Consaul & Lefkovitch).

Ironstone ranges are considered hotspots for higher plants α and β diversity. The lack of studies and the intense degradation of the ironstone ranges, due to mining, motivated us to compile, for the first time, a list of vascular plants collected on iron-rich derived substrates from ancient landscape of south-eastern Brazil. All existing records in the Brazilian Virtual Herbarium of Flora and Fungi for each of the 43 municipalities containing ironstone ranges were downloaded, resulting in 17,954 vouchers identified to the species level. We found 2,933 species belonging to 160 families and 818 genera. For the first time, we identified 148 species mentioned in endangered flora official lists and 48 narrow endemic species. Collecting efforts must still be supported to properly sample the vegetation since, for 143 sites, less than 10 records/site were found. This dataset will assist with the indication of dozens of plant species whose threat criteria must be urgently assessed to subsidise public policies on the use and conservation of the Brazilian flora.

Rare and endangered habitat types and vascular plant species were studied in the canyon associated with slope cirque “Gorodskaya shchel' (Town Crack)" in the southern part of Khibiny Mountains (Murmansk Region). Habitat types are interpreted based on a phytosociological approach (Braun-Blanquet classification). Habitat type “D4.2. Basic mountain flushes and streamsides, with a rich arctic-montane flora" of the Emerald Network (partly coincides with type 3220 “Alpine rivers and the herbaceous vegetation along their banks" of Council Directive 92/43/EEC) includes two associations: Mniobryo–Epilobietum hornemanniiNordhagen 1943 of alliance Mniobryo–Epilobion hornemanniiNordhagen 1943, сlass Montio–Cardaminetea Br.-Bl. et Tx. ex Klika et Hadač 1944, and Oxyrietum digynae Gjaerevoll 1956 of alliance Saxifrago stellaris–Oxyrion digynae Gjaerevoll 1956, class Salicetea herbaceae Br.-Bl. 1948. Habitat type “H2.6 Ultra-basic screes of warm exposures" of the Emerald Network is represented by community type Racomitrium spp.–Ranunculus glacialis (class Thlaspietea rotundifolii). These habitats harbor a number of Red Data Book species: 16 rare vascular plants including two species of the Red Data Book of Russia, four species of Red Data Book of Murmansk Region and ten species which need special attention to their state in the natural environment if the Murmansk Region occurred in the studied canyon, cirque and nearest surroundings. As the area is out of the borders of National Park “Khibiny" and has high conservation value, it is necessary to establish here the botanical nature monument.

A grass endemic to Mexico, Sporobolus atrovirens, was identified for the first time as a desiccation-tolerant resurrection plant. Nine species of desiccation-tolerant vascular plants were found in the highland area of Mexico, including four species of ferns (Cheilanthes and Pellaea species) and three species of Selaginella. Two other grasses collected were known desiccation-tolerant species distributed from South America (Cordoba) to North America (Georgia). The ferns Ch. bonariensis, Ch. integerrima, Ch. myriophylla and P. sagittata are newly reported as desiccation-tolerant plants. The osmoprotectant trehalose which has been recorded as rare in plants was found in air-dry foliage of representative species of widely different taxa (9–291 µM g–1 dry weight). The flora of desiccation-tolerant species in Mexico is discussed in connection with its ability to accumulate trehalose.

The paper aims to describe Russian approaches to inventory of vascular plants diversity in the Russian Arctic. In the study, the local flora method is used. It provides comparable data for spatial comparisons between different locations. The method includes the study of species distributions within a landscape, therefore the concept of “partial flora” was elaborated. A complex estimate “activeness” allows to assess a species role within the landscape. These theoretical concepts are applied at the local flora of a hardly accessible central part of the Gydansky Peninsula. The local flora numbers 191 vascular plant species. Altogether, 18 habitat types were distinguished with partial floras numbering from 15 to 75 species. The highest alfa-diversity was recorded on steep slopes, many rare species occurred there as well. These habitats occupied less than 10% of the area but provided almost 75% of local flora. Although the morphology of relief was better developed at this locality compare to the others at the Gydansky Peninsula, the intralandscape structure of flora is continuous, showing a low beta-diversity and high similarity of species composition between different habitats. It is explained by a high proportion of “active” species, which occur in many different habitat types. Along the zonal gradient within the Gydansky Peninsula, a decrease of species richness at local flora level was found but no change at partial floras level.

The paper provides brief information on the formation of the list of vascular plant species that need protection in the Jewish Autonomous Region. The author also reports about the current species composition in the regional Red Data Book. It is for the first time that a distribution and concentration of rare plant species in the region have been analyzed. It is revealed that the maximum density of protected plants is observed in the southern part of the Pompeevsky ridge, and among the administrative areas – in the Oktyabrsky district.

At Mount Albert, Quebec, many taxa are found exclusively on either serpentine or amphibolite contiguous formations. This exclusivity is clearly more noticeable within the saxicolous lichens than within the other groups. Serpentine seems to be an unfavourable substratum for the growth of saxicolous lichens. There are more infrequent taxa on serpentine than on amphibolite. The saxicolous, muscicolous, and terricolous lichen flora and the lichenicolous fungi of the plateau include 202 taxa, most of which have an arctic affinity. Of these taxa, 36 are recorded for the first time in Quebec, 16 in Canada and, 11 in North America. The ecological influence of serpentine on the lichens is, in many aspects, similar to that observed on vascular plants.

A comprehensive inventory of the vascular plants is provided for the alpine zone of Teresa Island in Atlin Provincial Park, British Columbia. A total of 161 taxa were identified from collections made during a research program conducted in the summers of 1974, 1975, and 1976. Of these taxa Arnica louiseana var. frigida, Draba lactea, Lupinus kuschei, Oxytropis huddelsonii, Poa lettermanii, Senecio sheldonensis, Senecio yukonensis, and Stellaria longipes var. edwardsii have a restricted or otherwise interesting distribution in British Columbia.Preliminary observations indicate that the local distribution of all the taxa is controlled by three environmental gradients: snow duration, moisture, and topography. Five different alpine habitat types are recognized as a result of different combinations of these gradients. These habitat types are (1) fell-fields and boulder fields, (2) meadows and shrub fields, (3) snow beds, (4) seepage sites, and (5) drainage areas. The habitat types and relative abundance of each taxon are listed.

Inselbergs are rounded rock outcrops, usually of Precambrian age, with sparse vegetation cover. The vegetation of inselbergs in Zimbabwe is described for the first time, based upon data sampled from 53 localities. Inselbergs support a range of habitats whose vegetation is described. Data on species richness and floristic composition of the inselberg flora (549 vascular plant, 25 bryophyte and 136 lichen species) are presented. Phytogeography and diversity of inselberg vegetation are discussed. First records for Zimbabwe are reported in lichens and vascular plants.

Nowadays, bioecological characteristics of species are the basis for flora and vegetation studying on the different levels. Bioecological characteristics of species is required in process of flora studying on the different levels such as biotopes or phytocenoses, floras of particular areas (floras of ecologically homogeneous habitats), and floras of certain territories. Ramensky scale is the one of first detailed ecological scales on plant species ordination in relation to various environmental factors; it developed in 1938 (Ramensky, 1971). A little later (1941), Pogrebnyak’s scale of forest stands was proposed. Ellenberg’s system developed in 1950 (Ellenberg, 1979) and Tsyganov’s system (Tsyganov, 1975) are best known as the systems of ecological scales on vascular plant species; these systems represent of habitat detection by ecotopic ecomorphs of plant species (phytoindication). Basically, the system proposed by Alexander Lyutsianovich Belgard was the one of first system of plant species that identiified ectomorphs in relation to environmental factors. As early as 1950, Belgard developed the tabulated system of ecomorphs using the Latin ecomorphs abbreviation; he also used the terminology proposed in the late 19th century by Dekandol (1956) and Warming (1903), as well as terminology of other authors. The article analyzes the features of Belgard’s system of ecomorphs on vascular plants. It has certain significance and advantages over other systems of ecomorphs. The use of abbreviated Latin names of ecomorphs in tabular form enables the use shortened form of ones. In the working scheme of Belgard’s system of ecomorphs relation of species to environmental factors are represented in the abbreviated Latin alphabetic version (Belgard, 1950). Combined into table, the ecomorphic analysis of plant species within association (ecological certification of species), biotope or area site (water area) gives an explicit pattern on ecological structure of flora within surveyed community, biotope or landscape, and on environmental conditions. Development and application by Belgrard the cenomorphs as «species’ adaptation to phytocenosis as a whole» were completely new in the development of systems of ecomorphs and, in this connection, different coenomorphs were distinguished. Like any concept, the system of ecomorphs by Belgard has the possibility and necessity to be developed and added. Long-time researches and analysis of literature sources allow to propose a new coenomorph in the context of Belgard’s system of ecomorphs development: silvomargoant (species of forest margin, from the Latin words margo – edge, boundary (Dvoretsky, 1976), margo – margin, ad margins silvarum – along the deciduous forest margins). As an example of ecomorphic characterization of species according to the system of ecomorphs by Belgard (when the abbreviated Latin ecomorph names are used in tabular form and the proposed cenomorph is used), it was given the part of the table on vascular plants ecomorphs in the National Nature Park «Orelsky» (Baranovsky et al). The Belgard’s system of ecomorphs is particularly convenient and can be successfully applied to data processing in the ecological analysis of the flora on wide areas with significant species richness, and the proposed ecomorph will be another necessary element in the Belgard’s system of ecomorphs.
