Abstract:

Prior to the beginning of a trap volcanism of Central Siberia there was a plain, covered by Cordaitanthales. Slope herbaceous cover consisted mainly of ferns. Equisetopsida prevailed in the swampy lowlands. Volcanic eruptions at the end of Vishkilian (Severodvinian) led to the formation of a hill. It was covered by similar vegetation, but vegetation of herbaceous slopes substantially prevailed. Woody vegetation was dominated at only two locations, it was also about 50% at three locations and absent at two ones. Associations of the grassy slopes in most places were at least 46%, they were about 100% in two places and absent in 42% of the places. Ferns dominated sharply. Todites (?) anthriscifolia, Todites (?) sibirica, Prynadaeopteris (?) karpovii, rarely Cladophlebis aff. taimyrensis were dominants. Sometimes Prynadaeopteris (?) venusta were codominants. Yavorskyia radczenkovii sometimes codominated among gymnosperms. The herbaceous cover of the lowlands was dominated by Equisetopsida. At two locations, they are about 100%, and more than 50% at two ones , and from 12 to 33% at four ones. They are absent only at two localities. Paracalamites were usually dominants. Sometimes hyllotheca turnaensis, P. minuta, Paraschizoneura codominated. In the basins, Palaeoanodonta (Bivalve) had a significant role. Thus, the composition of the flora of the Late Gagary-Ostrovian time has a little difference from the Early Gagary-Ostrovian, but the ecological differences are significant. Forest communities are inferior to the dominant role of herbaceous slopes ones. This makes the flora of the Late Gagary-Ostrovian time be similar to the followed Tutonchanian - Early Dvurogyan flora in the ecological sense.

Abstract:

Seven fossil–species can be distinguished within the range of late Carboniferous and early Permian equisetopsid (“horsetail”) foliage formerly assigned to Annularia stellata. The shoots bearing this foliage also produced distinctive strobili often known as Calamostachys tuberculata. These foliage species can be differentiated by leaf and whorl morphology, and each species has a distinct geographical and stratigraphical range. The group first appeared in the intramontane basins of the Variscan Mountains in the late Duckmantian, and then expanded into the lowland paralic coal swamps in the Bolsovian–Asturian. The group continued to flourish in coal swamp refugia during the Stephanian but eventually disappeared during the early Permian.

Abstract:

In sediments from Chignahuapan Lake, State of Mexico, Mexico, 96 palynomorphs were identified. Eight taxa were found for algae, one family with one genus both for Equisetopsida and Lycopodiopsida, and 6 families with 10 genera for Polypodiopsida. Pinophyta were represented by 3 families and 3 genera, Liliopsida by 10 families and 13 genera, and Magnoliopsida by 44 families and 50 genera. The temperate forest surrounding Chignahuapan lake included components such as Abies, Alnus, Pinus, Quercus and Salix; aquatic and subaquatic vegetation components such as Cyperus, Luzula, Myriophyllum, Typha and Schoenoplectus were also present. Human activity was inferred from the occurrence of Zea mays and Cucurbitaceae.

São detalhadas as características das estruturas reprodutivas de Equisetopsida procedentes de um nível pelítico associado a uma camada de carvão na área de Pântano Grande (Folha de Quitéria, Formação Rio Bonito, Artinskiano/Kunguriano) no Estado do Rio Grande do Sul. As partes vegetativas dessa planta, abundantes no nível estudado, são relacionadas ao gênero Phyllotheca Brongniart, 1828. Análises morfológicas detalhadas dos fragmentos férteis levaram ao reconhecimento da família Gondwanostachyaceae, e mais especificamente da espécie-tipo Gondwanostachys australis (Meyen, 1967). Os esporos “in situ” contidos nos esporângios são do tipo Calamospora. Compõem a megaflora, além das articuladas, formas foliares relacionadas a Glossopteris, Cordaites, Rhodea e Buriadia, além de estruturas férteis relacionadas a Arberiales. Uma rica associação esporopolínica (“Sporae dispersae”) foi identificada nesse mesmo nível. A associação é representada majoritariamente por esporos triletes, pólens monossacados, bissacados e algas.

Abstract:

The Oloy floristic assemblage comes from volcanic-sedimentary deposits of the Teleneut Unit, distributed in the Il’guveem river head, at the Oloy, Great Anuy and Yablon Rivers interfluve area. This area belongs to the Anadyr segment of the Okchotsk-Chukotka volcanic belt (Belyi, 1977). The Oloy floristic assemblage consists of 15 species. Equisetopsida: Equisetum sp. Polypodiopsida: Cladophlebis sp., Coniopteris sp., Tchaunia tchaunensis Samyl. et Philipp. Czekanowskiopsida: Phoenicopsis ex gr. angustifolia Heer. Cycadophytes: Heilungia oloensis Samyl. et Philipp., Taeniopteris sp., Pterophyllum sp. Ginkgoopsida: Ginkgo sp., Sphenobaiera sp. Pinopsida: Pagiophyllum zhuravlevii Golovn., Araucarites sp., Taxodium sp., Sequoia sp., Pityophyllum sp. Among them gymnosperms predominate. Angiosperms are not revealed. Cycadophytes are represented by three genera (Heilungia, Taeniopteris and Pterophyllum). Taxonomic composition of the Oloy floristic assemblage most closely resembles the composition of the Chaun flora, which comes from the Coniacian deposits of the Chaun Group of Central Chukotka. From 15 species of the Oloy assemblage 13 species are common with the Chaun ones (besides Taeniopteris иPterophyllum). Among common taxa there are the characteristic endemic plants of the Chaun flora: Tchaunia tchaunensis and Pagiophyllum zhuravlevii. The great systematic similarity of these floras indicate that they were even-aged and belonged to the single phytogeographic area – the Chukotka subprovince of the Mountain Okchotsk-Chukotka province (Golovneva, 2014b).

Abstract:

Ferns (Pteridophyte) are members of the kingdom plantae that contribute to Indonesia's biodiversity, especially the diversity of flora. Ferns have an important role in maintaining the balance of the ecosystem. In addition to having ecological value in the ecosystem as a source of germplasm, ferns also have the potential to be useful to support people's lives. However, in fact ferns are still less well-known and receive less attention than other plants. This is because one of the reasons is that people are less familiar with ferns. This study aims to identify the types of ferns (Pteridophyte) in the mountainous area of Buntu Sarong Village, Masalle District, Enrekang Regency. Data collection was carried out using the exploration method at certain points in the research location that were considered potential, then recording, documenting, identifying and classifying the Pterydophyta found. The research at the research location successfully identified and documented 16 species of Pteridophyte, namely Psilotum nudum, Lycopodium, Selaginella delicatula, Equisetum hyemale, Odontosoria chinensis, Gleichenia linearis, Adiantum sp., Christella parasitica, Aspelinum nidus, Cyathea cooperi, Angiopteris evecta, Deparia petersenii, Microsorum punctatum, Drynaria quercifolia, Microsorum punctatum, Microsorum scolopendria, Drymoglossum piloselloides. The identified Pteridophyte are classified into 13 families (Lycopodiaceae, Psilotaceae, Equisetaceae, Marattiaceae, Lindsaceae, Gleicheniaceae, Adiantaceae, Thelypteridaceae, Asplenidaceae, Chyatheaceae, Athyriaceae, Polypodiaceae) and 5 classes (Lycopodiopsida, Psilotopsida, Equisetopsida, Marattiopsida, Polypodiopsida).

Abstract:

It is known that phytosterols have high immunomodulating, hypocholesterolemic and oncoprotective activity and are widely used in medicine. In addition, the plants containing them are used in feed of farm animals as dietary supplements that stimulate growth and the immune system. Promising, but poorly studied, sources of these biologically active compounds may be plants of the class Horsetails (Equisetopsida), grown under extreme conditions of sharply continental climate of Yakutia. The steric composition of the aerial part of the variegated horsetail (Equisétum variegatum) was studied for the first time during the summer and autumn vegetation. It is shown that the composition of the main free sterols includes β-sitosterol, campesterol, stigmasterol, isofucosterol, as well as a small amount of cholesterol. The total amount of free and bound sterols in the tissues of the aerial part of this species is about 0.5 mg/g dry weight or 2% of the total content of all lipid components. Moreover, the content of free sterols in the aerial part of variegated horsetail is an order of magnitude higher than the content of sterol esters in these tissues. Peculiarities of the seasonal (autumn-summer) dynamics of changes in the relative contents of stigmasterol, campesterol and isofucosterol and the absolute total content of sterols in the aerial part of variegated horsetail are revealed.

Abstract:

Collections of fossil plants from the Upper Cretaceous volcanogenous deposits of Eastern Chukotka were studied. Floristic assemblages were divided into two groups of diff erent age: the Coniacian and Santonian — late Campanian. The Amguema flora includes assemblages from the Tumaninskaya and Leurvaam Formations. This flora consists of 23 taxa: Equisetopsida: Equisetum sp. Polypodiopsida: Coniopteris tschuktschorum (Krysht.) Samyl., Asplenium sp., Cladophlebis sp. Cycadopsida: Taeniopteris sp., Heilungia sp. Ginkgoopsida: Ginkgo ex gr. sibirica Heer, Ginkgo ex gr. adiantoides (Ung.) Heer, Sphenobaiera sp. Czekanowskiopsida: Phoenicopsis ex gr. angustifolia Heer, Ph. steenstrupii Seward. Pinopsida: Taxodium amguemensis (Efimova) Golovn., Sequoia sp., Metasequoia sp., Cupressinocladus sp., Pagiophyllum zhuravlevii Golovn., Cunninghamia orientalis (Philipp.) Samyl., Pityophyllum sp., Pityostrobus sp., Pityolepis sp. Magnoliopsida: Trochodendroides sp., Quereuxia angulata (Newb.) Krysht. ex Baik., Platanaceae indet. Among them gymnosperms (17 species) predominate. Ferns (3 species) and angiosperms (3 species) are less abundant. Shoots of Taxodium and floating rosettes of water plant Quereuxia angulata are frequent in collection. Prevalence of these remains and composition of sediments (thinly laminated siltstone and mudstone) allows to suggest that the Amguema flora reflects vegetation, which was distributed along banks of standing water or small calm rivers. This flora consists mostly from species of wide stratigraphic distribution. The occurrence of Cunninghamia orientalis (Philipp.) Samyl., which are characteristic species of the Ola and Arkagala floras, suggeststhe Santonian — late Campanian age of the Amguema flora. The Vovoveem floristic assemblage and isolated fi ndings from the Osinovskaya, Ekityki Formations and Amgen Unit belong to second group. Species, characteristic for the Chaun flora of Central Chukotka (Kolymella raevskii Samyl. et Philipp., Tchaunia tchaunensis Samyl. et Philipp., Ctenis paljavaensis Philipp., Araucarites subacutensis Philipp., Trochodendroides microphylla Philipp., Heilungia gajmanensis Samyl. Et Shczep.) predominate in this group. On this base the age of this group is determined as the Coniacian. Findings of characteristic species of the Chaun flora indicate that the area of this flora was not limited by the territory of the Chaun Group distribution and continued also in Eastern Chukotka.

Abstract:

The results of the study of the species composition of higher aquatic and coastal-aquatic plants of the Zolotynka River within the Chernihiv region are presented. The surveyed parts of the river revealed an increase in 42 species from 33 genus and 24 families. Small rivers serve as water storage for big rivers, they are of high ecological status which calls for improvement. One indicator of the status of small rivers is higher water and coastal-water plants, which react first to changes in the quality of the water body. By their species composition, projective cover, indicative properties and other characteristics it is possible to assess the ecological status of the river. The study was conducted in the course of 2017–2019. The material was collected during expeditionary studies of the valley of Zolotynka river (Chernihiv district, Chernihiv region). Zolotynka river belongs to Desna river basin and is its left tributary of the first order, its length is 13 km, the slope is 0.23 m/km, the area of the basin is 31.8 km². The river originates in the west of the village of Ivanivka, Chernihiv district of Chernihiv region. It flows southwest through the village of Zolotynka and joins Desna river. According to the results of expeditionary field research into the flora of Zolotynka river there are 42 species of higher water and coastal-water plants belonging to 33 genus, 24 families, 3 classes (Equisetopsida, Liliopsida and Magnoliopsida) and 2 divisions (Equisetophyta and Magnoliophyta). According to the classification of V.H. Papchenkova higher water and coastal- water flora of Zolotynka river belongs to 5 ecotypes, the largest of which is represented by a group of coastal- water plants – 27 species belonging to two ecotypes - gelophytes, or air-aquatic plants - 6 species and hygrogelophytes - 21 species. Analysis of the areological structure showed that species with a wide range of distribution make up almost 85%, according to the structure of life forms perennial herbaceous plants make up 90%, according to K. Raunkier’s classification hemicryptophytes predominate. According to the research findings there are 2 species that are subject to regional protection in Chernihiv region and a species recorded in the Red Data Book of Ukraine.

Full text

Abstract:

The coal-bearing lower Clackmannan Group of Scotland has yielded diverse fossil floras of Serpukhovian (late Mississippian) age dominated by arborescent lycopsids, equisetopsids, ferns and lyginopteridalean pteridosperms. Similar macrofloras of the same age have been reported from coal-bearing deposits of Maine-et-Loire (NW France) and Upper Silesia (Czech Republic and Poland). These fossil floras together reflect the earliest development of the coal swamp biome in tropical Euramerica. The biome appeared on newly-exposed areas of coastal plain that formed as result of lowered sea-levels during the first major cooling phase of the Late Palaeozoic Ice Age. A new combination Artisophyton chalmersii is proposed based on Megaphyton chalmersii Goodlet.

Abstract:

This paper deals with Paracalamitina striata (Schmalhausen) Zalessky, 1934, an equisetophyte of the family Tschernoviaceae from the Permian of Angaraland. New material contributes to a better understanding of this plant, which now can be reconstructed. Paracalamitina striata is an equisetopsid with opposite ribs on the stem. Its main stem bears lateral shoots or shoot and leaf scars, that are located at nodes. Shoot nodes have subcylindrical leaf sheaths. The distal parts of leaves are free and acute. Generative organs are fertile zones, which are formed by numerous sporangiophores with peltate sporophylls. A terminal sterile whorl is presented above each fertile zone. An emended diagnosis of Paracalamitina Zalessky is provided on the basis of new material and re-examination of previously collected specimens as well. The nomenclature and taxonomic status of P. striata also are discussed.

Abstract:

We are interested by studying the influence of two drying methods: in the shade and solar energy, on phytochemical composition. For this, we choose the rhizomes of the plant Equisetopsida Asterales, a species that can be found in the poor soil of Provence and Corsica. It prefers dry, sunny places in the Mediterranean. It is native to Southwest Asia, the East and spread in North Africa (Algeria, Morocco, Tunisia, Libya), Australia and the Americas, and Europe (Greece, Italy, France, Portugal, Spain). Equisetopsida Asterales rhizomes are used in Algeria as a traditional cream, which contributes to the disappearance of scars generated by burning. The antimicrobial properties of medicinal and aromatic plants have been known since antiquity. However, it was not until the early 20th century that scientists are beginning to show interest. It is known that the treatment of microbial infection is mainly based on the use of antibiotics, several work is devoted to the study of the antimicrobial power of essential oils. After some experiences in this work, the important result was obtained, time of Equisetopsida Asterales by solar energy is better than shade; and yield of essential oil extracted is better from the rhizomes dried by solar energy.

Abstract:

История коллекции тропических и субтропических растений Ботанического сада СПбГЛТУ насчитывает 175 лет с 1834 г., когда на территории СанктПетербургского Форст института была построена первая оранжерея. На протяжении почти двух веков коллекция формировалась и использовалась для обеспечения учебного процесса. В XIX начале XX вв. каталогизация коллекционных фондов проводилась по системе А. Энглера, начиная с 80х годов прошлого века по системе А.Л. Тахтаджяна. В работе представлен обзор коллекции тропических и субтропических растений на основе современных международных классификаций: APG IV, PPG I и т. д., основанных на молекулярных исследованиях и насчитывает 1344 таксона из которых 996 видов, 65 разновидностей и 283 культивара. Все растения относятся к классу Equisetopsida C.Agardh, и входят в состав 7 подклассов, 53 порядков, 124 семейств и 428 родов. Коллекция птеридофитов представлена тремя порядками и включает 14 семейств, 25 родов, 52 вида и 14 культиваров (66 таксонов). Коллекция голосеменных содержит 4 подкласса, 6 порядков, 9 семейств, 17 родов, 24 вида и 5 сортов (29 таксонов). Коллекция покрытосеменных имеет один подкласс Magnoliidae, 10 надпорядков, 41 порядок, 101 семейство, 386 родов, 920 видов, 65 тпр, 264 культивара (1249 таксонов). Международноунифицированный подход к классификации растений является важным шагом в усилении международной стандартизации обучения. The history of the collection of tropical and subtropical plants of the Botanical Garden of St. Petersburg State Forest Technical University is 175 years old. It dates back to 1834, when the first greenhouse was built on the territory of the St. Petersburg Forest Institute. For almost two centuries, the collection was formed and used to support the educationprocess. In XIX and early XX centuries cataloging of collection funds was carried out according to the system of A. Engler, starting from 1980s, according to the system of A.L. Tahtajyan. The paper presents a review of the collection of tropical and subtropical plants based on modern international classifications (APG IV, PPG I, etc.), based on molecular studies. The collection accounts for 1344 taxons of which 996 species, 65 varietiesand 283 cultivars. All plants belong to the class Equisetopsida C.Agardh, and are included in 7 subclasses, 53 orders, 124 families and 428 genera. The pteridophyte collection is represented by three orders and includes 14 families, 25 genera, 52 species and 14 cultivars (66 taxa).The angiosperm collections have one subclass Magnoliidae, 10 superorders, 41 orders, 101 families, 386 genera, 920 species, 65 varieties, 264 cultivars (1249 taxa). This internationally unified approach to the classification of plants is an important step in strengthening the international standardization of training.

Abstract:

Purpose. Determination of the species composition and determination of the systematic and ecological structure of the aquatic and coastal-aquatic flora of the Vyzhivka River. Methods: morphological, botanical, comparative ecology, statistical. The ecological classification of species was given according to V. Papchenkov. Results. Flora of the Vyzhivka River has 36 species of higher aquatic and coastal-aquatic plants belonging to 31 genus, 20 families, 14 orders, 3 classes (Equisetopsida, Liliopsida and Magnoliopsida) and 2 divisions (Equisetophyta and Magnoliophyta). The Magnoliophyta division includes 35 species, or 97,22% of the total number of species. The species composition is dominated by representatives of the class Liliopsida. Up to 4 families of flora (Alismataceae, Hydrocharitaceae, Cyperaceae, Lemnaceae) own 41,66% of all species. The ecological structure of aquatic and coastal-aquatic plants of Vyzhivka river includes four ecotypes. The first place in terms of the number of species is occupied by hydrophytes, which amount 33,33% of the total number of species, hygrohelophytes are represented by 30,56%. The share of helophytes and hygrophytes, respectively, is 19,44% and 16,67%. Conclusions. As a result of the conducted research, the species composition and features of the ecological structure of the higher aquatic and coastal-aquatic flora of the Vyzhivka River were established. The greatest species diversity is characteristic for the plot number 1 – 24 species. In the second section, 21 species of aquatic and coastal aquatic plants were identified. The smallest number – 18 species, is in the third area. The anthropogenic factors have the greatest impact on biodiversity: the presence of a drainage system, straightening of the riverbed, the use of the river basin for agricultural needs, the discharge of insufficiently treated sewage of housing and communal services.

Abstract:

AbstractPremiseCladoxylopsids, one of the first lineages with complex organization to rise from the plexus of structurally simple plants that comprised the earliest euphyllophyte floras, are moniliformopsid euphyllophytes. They formed Earth's earliest forests by the Middle Devonian and are thought to have given rise to the equisetopsids and probably some fern lineages. The Lower Devonian (Emsian) Battery Point Formation (Quebec, Canada) contains previously unrecognized cladoxylopsids preserved anatomically. One of these provides new data on structural evolution among euphyllophytes and is described here.MethodsThe anatomy and morphology of permineralized axes of the new plant were studied with light and electron microscopy on sections produced using the cellulose acetate peel technique. Morphological comparisons and phylogenetic analysis were used for taxonomic placement of the plant.ResultsThe plant represents a new species, Paracladoxylon kespekianum Chu et Tomescu, gen. et sp. nov., that has tracheids with modern‐looking bordered pits and the complex cauline vascular architecture characteristic of the genus Cladoxylon. Its dissected ultimate appendages have complex regular taxis and a pattern of vascularization that suggests bilateral symmetry.ConclusionsParacladoxylon kespekianum is one of the largest Early Devonian euphyllophytes, among the oldest representatives of the cladoxylopsid group, and older than any species of the closely related Cladoxylon by at least 35 million years. It is also one of the oldest anatomically preserved representatives of the cladoxylopsid group. Its anatomical organization pushes the rise of complex vascular architecture among moniliformopsid euphyllophytes deeper in time than previously recognized.
