"National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment. -
Euphorbiaceae
Botanische Bestimmungsübungen 1 Euphorbiaceae Euphorbiaceae (Wolfsmilchgewächse) 1 Systematik und Verbreitung Die Euphorbiaceae gehören zu den Eudikotyledonen (Kerneudikotyledonen > Superrosiden > Rosiden > Fabiden). Innerhalb dieser wird die Familie zur Ordnung der Malpighiales (Malpighienartige) gestellt. Die Euphorbiaceae umfassen rund 230 Gattungen mit ca. 6.000 Arten. Sie werden in 4 Unterfamilien gegliedert: 1. Cheilosoideae, 2. Acalyphoideae, 3. Crotonoideae und 4. Euphorbioideae sowie in 6 Triben unterteilt. Die Familie ist überwiegend tropisch verbreitet mit einem Schwerpunkt im indomalaiischen Raum und in den neuweltlichen Tropen. Die Gattung Euphorbia (Wolfsmilch) ist auch in außertropischen Regionen wie z. B. dem Mittelmeerraum, in Südafrika sowie in den südlichen USA häufig. Heimisch ist die Familie mit Mercurialis (Bingelkraut; 2 Arten) und Euphorbia (Wolfsmilch; 20-30 Arten) vertreten. Abb. 1: Verbreitungskarte. 2 Morphologie 2.1 Habitus Die Familie ist sehr vielgestaltig. Es handelt sich um ein- und mehrjährige krautige Pflanzen, Halbsträucher, Sträucher bis große Bäume oder Sukkulenten. Besonders in S-Afrika und auf den Kanarischen Inseln kommen auf hitzebelasteten Trockenstandorten zahlreiche kakteenartige stammsukkulente Arten vor, die in den Sprossachsen immens viel Wasser speichern können. © PD DR.

Vascular Plant Species Diversity of Mt. Etna
Vascular plant species diversity of Mt. Etna (Sicily): endemicity, insularity and spatial patterns along the altitudinal gradient of the highest active volcano in Europe Saverio Sciandrello*, Pietro Minissale* and Gianpietro Giusso del Galdo* Department of Biological, Geological and Environmental Sciences, University of Catania, Catania, Italy * These authors contributed equally to this work. ABSTRACT Background. Altitudinal variation in vascular plant richness and endemism is crucial for the conservation of biodiversity. Territories featured by a high species richness may have a low number of endemic species, but not necessarily in a coherent pattern. The main aim of our research is to perform an in-depth survey on the distribution patterns of vascular plant species richness and endemism along the elevation gradient of Mt. Etna, the highest active volcano in Europe. Methods. We used all the available data (literature, herbarium and seed collections), plus hundreds of original (G Giusso, P Minissale, S Sciandrello, pers. obs., 2010–2020) on the occurrence of the Etna plant species. Mt. Etna (highest peak at 3,328 mt a.s.l.) was divided into 33 belts 100 m wide and the species richness of each altitudinal range was calculated as the total number of species per interval. In order to identify areas with high plant conservation priority, 29 narrow endemic species (EE) were investigated through hot spot analysis using the ``Optimized Hot Spot Analysis'' tool available in the ESRI ArcGIS software package. Results. Overall against a floristic richness of about 1,055 taxa, 92 taxa are endemic, Submitted 7 November 2019 of which 29 taxa are exclusive (EE) of Mt. -

Faried1 and Mona H. 1* Mohamed 1Botany and Microbiology Department, Faculty of Science, Assiut University, Assiut, 2Botany and Microbiology Department, Faculty of Science, Helwan University, Helwan, Egypt. Received April 30, 2019; Revised June 16, 2019; Accepted July 12, 2019 Abstract Euphorbia L. (Euphorbiaceae) is the largest genus of flowering plants in the flora of Egypt. The present paper deals with the study of leaf architecture including venation patterns, marginal configuration and leaf shape characters in the Euphorbia species in Egypt. A classical clustering analysis (UPGMA) and principle component analysis (PCA) by PAST 2.17c ٥7 architectural leaf characters to discriminate the investigated taxa. Plates of light softwere are conducted based on microscope for cleared leaf, marginal ultimate veins details as well as tooth shape for studied taxa were provided. Results from multivariate analysis are kept in line with the traditional taxonomic sections of the genus in Egypt. The obtained phenogram is slightly matched with the tradition and modern classification of genus Euphorbia. The arrangement and attachment of leaves, laminar size, apex and base leaf features, symmetry of base and medial of blade, primary vein framework, major secondary veins course, minor secondary veins, tertiary veins course and areolation development have been considered to be the most important distinguishable characters in Euphorbia. Leaf morphology and venation characters can be considered as good taxonomic indicators in segregating Euphorbia heterophylla in a distinct section (Poinsettia) within subgenus Chamaesyce, in addition they can discriminate the closely related species of Euphorbia as shown in the constructed key. -
Review and Advances in Style Curvature for the Malvaceae Cheng-Jiang Ruan*
® International Journal of Plant Developmental Biology ©2010 Global Science Books Review and Advances in Style Curvature for the Malvaceae Cheng-Jiang Ruan* Key Laboratory of Biotechnology & Bio-Resources Utilization, Dalian Nationalities University, Dalian City, Liaoning 116600, China Correspondence : * [email protected] ABSTRACT The flowers of the Malvaceae with varying levels of herkogamy via style curvature have long intrigued evolutionary botanists. This review covers the flower opening process, approach herkogamy, style curvature and character evolution based on molecular phylogenetic trees, adaptive significances of style curvature and the mating system in some portions of the genera in this family. Hermaphroditic flowers of some species have showy petals and pollen and nectar rewards to pollinators. Approach herkogamy, in which stigmas are located on the top of a monadelphous stamen, has evolved as a mechanism to reduce the frequency of intra-floral self-pollination or the interference between male-female organs. Protandrous or monochogamous flowers in the fields open at about 5-7 days and 1-2 days respectively, and pollination is conducted by insects and birds. Interestingly, un-pollinated styles in some species curve when pollination fails. According to our observations and published or internet data, this curvature occurs in 23 species distributed in eight genera of four tribes (Malvavisceae, Ureneae, Hibisceae, Malveae) and appears to have evolved at least eight times. A shift to use style curvature is associated with a shift to annual or perennial herbs, and an unpredictable pollinator environment is likely an important trigger for this evolution. The adaptive significances of style curvature in the Malvaceae include delayed selfing, promotion of outcrossing or reduction in intrafloral male-female interference, sometimes two or three of which simultaneously occur in style curvature of one species (e.g., Kosteletzkya virginica). -

Gianguzzi1, D. Cusimano1, S. Romano2 1Department of Agricultural and Forest Sciences, University of Palermo, Via Archirafi 38 - I-90123 Palermo, Italy. 2Department of Earth and Marine Sciences, University of Palermo, Via Archirafi 22 - I-90123 Palermo, Italy. Abstract A work on the Celtis tournefortii subsp. aetnensis vegetation, endemic species located in disjointed sites in the Sicilian inland, is here presented. It forms microwoods with a relict character established on screes and detrital coverages, on a variety of lithological substrates (volcanics, limestones, quartzarenites). Based on the phytosociological analysis carried out in the territory, these vegetation aspects are framed in the alliance Oleo-Cerato- nion, within which a new association (Pistacio terebinthi-Celtidetum aetnensis) is described, in turn diversified in the following subassociations: a) typicum subass. nova, on detrital calcareous cones of the north-western part of Sicily, in the Palermo province (Rocca Busambra, Pizzo Castelluzzo and northern slopes of Pizzo Telegrafo); b) phlomidetosum fruticosae subass. nova, typical of carbonate megabreccias, on the most xeric sou- thern slopes of Pizzo Telegrafo (Caltabellotta territory, Agrigento province); c) artemisietosum arborescentis subass. nova, typical of quartza- renitic outcrops on the Nebrodi Mts. inland (Cesarò territory, Messina province); d) rhamnetosum alaterni subass. nova, widespread on cracked lava flows of the western side of Mount Etna (Catania province).
