An overview of all hawkweeds (Hieracium L.) recorded on the Putorana Mountains is given. The list of floristic findings of the territory of the Plateau includes 3 new species (Hieracium czamyjashense Tupitz., H. pseudarctophilum Schljakov., H. pseudofariniramum Tupitz.). New localities are also given for the endemic species H. putoranicum Tupitz. and the rare species H. subfariniramum (Ganesch et. Zahn) Ȕksip ex Tupitz.. The coordinates of collection sites, dates of collection, habitats nature, area type and an ecological-cenotic confinedness are given for each species. The nomenclature is reviewed. Field studies were carried out in 2018 in the western part of the Putorana Mountains, on the western coast of Lake Sobachye (Yt-Kyuyol) near the mouth of the Nakhta River; in 2019 in the western part of the Putorana Mountains, in the vicinity of Talnakh Town, at the Red Rocks Natural Sanctuary of regional significance; in 2020 in the south-west of the Putorana Mountains, in the vicinity of the middle part of Lake Kutaramakan (mouth of the Irkingda River) on the territory of the Putoransky Nature Reserve and its protective zone. Moreover, the herbarium specimen of H. umbellatum L. from the vicinity of Snezhnogorsk Town is published.

AbstractA well-preserved fauna of largely articulated trilobites is described from three new localities close to one another in the Bull River Valley, southeastern British Columbia. All the trilobites from these localities are from the lower or middle part of the Wujiajiania lyndasmithae Subzone of the Elvinia Zone, lower Jiangshanian, in the McKay Group. Two new species are proposed with types from these localities: Aciculolenus askewi and Cliffia nicoleae. The trilobite (and agnostid) fauna from these localities includes at least 20 species: Aciculolenus askewi n. sp., Agnostotes orientalis (Kobayashi, 1935), Cernuolimbus ludvigseni Chatterton and Gibb, 2016, Cliffia nicoleae n. sp., Elvinia roemeri (Shumard, 1861), Grandagnostus? species 1 of Chatterton and Gibb, 2016, Eugonocare? phillipi Chatterton and Gibb, 2016, Eugonocare? sp. A, Housia vacuna (Walcott, 1912), Irvingella convexa (Kobayashi, 1935), Irvingella flohri Resser, 1942, Irvingella species B Chatterton and Gibb, 2016, Olenaspella chrisnewi Chatterton and Gibb, 2016, Proceratopyge canadensis (Chatterton and Ludvigsen, 1998), Proceratopyge rectispinata (Troedsson, 1937), Pseudagnostus cf. P. josepha (Hall, 1863), Pseudagnostus securiger (Lake, 1906), Pseudeugonocare bispinatum (Kobayashi, 1962), Pterocephalia sp., and Wujiajiania lyndasmithae Chatterton and Gibb, 2016. Pseudagnostus securiger, a widespread early Jiangshanian species, has not been previously recorded from southeastern British Columbia. Non-trilobite fossils collected from these localities include brachiopods, rare trace fossils, a complete silica sponge (Hyalospongea), and a dendroid graptolite. The faunas from these localities are more diverse and better preserved than those from other previously documented localities of the same age in the region.Additional specimens of a rare species, found by amateur collectors in previously documented localities of slightly younger age (upper part of Wujiajiania lyndasmithae Subzone) in the same region, are documented. These new specimens, when combined with an earlier discovered specimen, provide adequate type material to propose a new species of Labiostria, L. gibbae, which may be useful for biostratigraphy.UUID:http://zoobank.org/89551eac-b3af-4b2b-8ef3-7c2e106a560d

The first data about the algae flora of the water bodies of the “Aschisayskaya Steppe” plot of the State Nature Reserve “Orenburgsky” are presented. 217 species and intraspecies taxa of microalgae belonging to the phyla Chlorophyta, Euglenozoa, Bacillariophyta, Ochrophyta, Streptophyta, Miozoa and Cyanobacteria were found in five reservoirs of the plot. New species for the territory of the Orenburg Region, as well as rare species for Russia are noted, their characteristics and micrographs are given. The obtained data expands the current understanding of the range of the identified taxa.

The results of field studies of the lichen flora of the Kerzhensky Reserve (Nizhny Novgorod Region), carried out mainly in the Kerzhenets River valley in May 2019, are presented. An annotated list of taxa previously unknown for the reserve includes 121 species from 70 genera. Of these, 97 species and 31 genera are new to the Nizhny Novgorod Region. The species Micarea soralifera and Rinodina excrescens are published for the first time for European Russia. We have found some very rare species in European Russia previously known from single records (Agonimia repleta, Bacidina indigens, Gyalideopsis alnicola, Sclerophora amabilis, Stigmidium mycobilimbiae, Telogalla olivieri, and Verrucaria ochrostoma).

AbstractThe aim of the present work conducted in the area of Międzyrzeki Strict Nature Reserve in the Roztocze National Park was to show new sites of rare and species new to Poland from the Kobayasiella genus (K. okadae (Skvortzov) Lange-Bert., K. tintinnus Buczkó, Wojtal & Jahn) with regard to morphological and ecological characteristics. Chemical parameters show that investigated habitats are poor and oligotrophic with a low content of chlorides, sulfates and nitrates. K. okadae, K. subtilissima (Cleve) Lange-Bert. and K. tintinnus were found in the studied area. The authors suggest the use of synonym Navicula hoeflerii Cholnoky for the Kobayasiella okadae. LM and SEM images were used in the analysis of the material.

A new diatom species, Sellaphora constrictum sp. nov., is reported from a karst landform in the Maolan Nature Reserve, Guizhou Province, China. Valves of the new species are broadly linear, slightly constricted in the middle part of the margins and have round apices, an undulate filiform to lateral raphe, a narrow axial area and a narrow conopeum bordering axial area on each side. This species also has undulate ridges along the margin and near the center of the valve, giving the impression of longitudinal ridges on either side of the axial area under light microscopy. Internally, a round opening is present in the apex of the valve, and thickened transverse bars are absent in this region. There are two types of areolae on the valve exterior. Together these features distinguish the new species from all others currently assigned to the genus. We discuss the growing number of new species and genera from freshwater environments in China, and interpretations about the delineation of the genus Sellaphora.

Abstract A new species of Diderma (Physarales, Didymiaceae) was recorded in the Mata Estrela Private Nature Reserve, Rio Grande do Norte state. It is characterized by sessile sporangia, white globose columella, capillitium irradiating from the peridium, forming three layers, the middle part strongly calcareous, the outer layer cartilaginous and the inner layer membranous. A key to species of sessile sporangia Diderma with triple peridium is presented.

We here describe a new species, Vincetoxicum luridum, from South West Balochistan. Scanning electron microscopy (SEM) of leaves and seeds, palynology and chorology support the recognition of V. luridum. The lurid appearance, dense pubescence and ovate corona lobes readily distinguish V. luridum from the closely related species V. stocksii which is endemic to North East Balochistan. We illustrate V. luridum, and confirm the significance of corona morphology for classification of Vincetoxicum in Pakistan. Presently, the V. arnottianum complex comprise four species with purple flowers viz., V. arnottianum, V. sakesarense, V. luridum and V. stocksii. In this study we also present the geographic distribution and a taxonomic key to the taxa of V. arnottianum complex.

During our field studies of saline meadows, salt marshes and swampy flora carried out near the Backi Monostor and Melenci villages (Vojvodina, Serbia) several specimens of the genus Ranunculus L. (Ranunculaceae) were found and identified as Ranunculus polyphyllus Waldst. & Kit. ex Willd. Apart from two records from the beginning of the last century, the appearance of this rare species has been uncertain in the flora of Serbia. We confirmed its presence at one known and two new localities in salt marsh and aquatic floating communities. Also, this is the first herbarium evidence of the presence of this species in Serbia.

The herbarium material collected in 2012–2017 in Cambodia and Laos provides data on 281 new localities of 110 orchid species from 48 genera for Laos, and 4 new localities of 4 species from 4 genera for Cambodia. Among them, 3 species present new records for the flora of Cambodia (Eria ochracea Rolfe, Luisia macrotisRchb. fil., Trichoglottis seidenfadenii Aver.); 1 genus (Abdominea J. J. Sm.), and 13 species are new to the flora of Laos (Abdominea minimiflora (Hook. fil.) J. J. Sm., Bulbophyllum nanopetalum Seidenf., Chiloschista parishii Seidenf., Cleisostoma tricornutum Aver., Didymoplexis vietnamica Ormerod, Gastrochilus hainanensis Z. H. Tsi, Hetaeria alata Ridl., Malleola seidenfadenii Christenson, Phaius takeoi (Hayata) H. J. Su, Sarcoglyphis yunnanensis Z. H. Tsi, Schoenorchis fragrans (E. C. Parish et Rchb. fil.) Seidenf. et Smitinand, Thrixspermum fragrans Ridl., T. hystrix (Blume) Rchb. fil.). One new species is described, Bulbophyllum pseudorufinum Aver. The reported data provide a substantial basis for the understanding of the present-day distribution of rare species in Eastern Indochina.
