DOI: 10.3897/phytokeys.131.32173

Authors: Javier Martínez-Fort, Maela León, Maria P. Donat-Torres

Abstract: We describe Peucedanum officinale L. subsp. album Martínez-Fort & Donat-Torres subsp. nov., in which we grouped the thermomediterranean populations scattered along the eastern part of the Iberian Peninsula. The characters that differentiate this new subspecies from other infraspecific taxa in Peucedanum officinale are its canaliculated leaflet, the inflorescences much branched and lack of dominant terminal umbels, the umbels are few rayed, sometimes sessile and lateral, the petals are white and the fruit pedicels short, the same or shorter in length than the fruit. We provide here a full description of the new subspecies based on herbarium specimens and field measurements, as well as providing dichotomous keys to the subspecies within P. officinale. In addition, we provide a comparison of the ITS sequences of nrDNA with the most closely related taxons.

Study of the leaf anatomy in cross-section in the Iberian species of Festuca L. (Poaceae) and its systematic significance https://phytokeys.pensoft.net/article/13746/ PhytoKeys 83: 43-74

DOI: 10.3897/phytokeys.83.13746

Authors: Gloria Martínez-Sagarra, Pilar Abad, Juan Antonio Devesa

Abstract: A study of the leaf anatomy in the species of the genus Festuca present in the Iberian Peninsula was made. A total of 68 taxa were included and 15 characters were measured in leaf cross-section. The major anatomical features of each taxonomic group were characterized, and some variability was observed in the taxa. The anatomical patterns observed were compared and discussed with the relationships suggested by the molecular analyses. The leaf outline, the presence or absence of complete girders, and the development degree of the bulliform cells were the main characters to differentiate among fescue species of the fine-leaved clade and those of the broad-leaved clade. The most useful character to segregate species groups within the different taxonomic sections was the arrangement of the sclerenchyma, and a remarkable variability of this character was found in the species of Festuca section Festuca, especially in those located in other lineages according to molecular markers. Most of the anatomical patterns were not exclusive of the sections or lineages, and only some taxa could be anatomically differentiated at species level based on a set of non-taxative characters. The discordant pattern observed in F. henriquesii, a species traditionally included in Festuca sect. Festuca that shared anatomical features with the species of “F. rubra complex”, suggests its possible inclusion in the sect. Aulaxyper pending further taxonomic and phylogenetic analyses.

Dataset of herbarium specimens of threatened vascular plants in Catalonia https://phytokeys.pensoft.net/article/11542/ PhytoKeys 77: 41-62

DOI: 10.3897/phytokeys.77.11542

Authors: Neus Nualart, Neus Ibáñez, Pere Luque, Joan Pedrol, Lluís Vilar, Roser Guàrdia

Abstract: This data paper describes a specimens’ dataset of the Catalonian threatened vascular plants conserved in five public Catalonian herbaria (BC, BCN, HGI, HBIL and MTTE). Catalonia is an administrative region of Spain that includes large autochthon plants diversity and 199 taxa with IUCN threatened categories (EX, EW, RE, CR, EN and VU). This dataset includes 1,618 records collected from 17th century to nowadays. For each specimen, the species name, locality indication, collection date, collector, ecology and revision label are recorded. More than 94% of the taxa are represented in the herbaria, which evidence the paper of the botanical collections as an essential source of occurrence data.

Taxonomy and nomenclature of the polymorphic European high mountain species Androsace vitaliana (L.) Lapeyr. (Primulaceae) https://phytokeys.pensoft.net/article/10731/ PhytoKeys 75: 93-106

DOI: 10.3897/phytokeys.75.10731

Authors: Christopher J. Dixon, Walter Gutermann, Peter Schönswetter, Gerald M. Schneeweiss

Abstract: Androsace vitaliana (syn. Vitaliana primuliflora; Primulaceae) has been subject to several taxonomic treatments, whose conclusions ranged from a single species with numerous infraspecific taxa to several species usually without infraspecific taxa. Here, following molecular investigation, several taxonomic changes are made. A single species with the following infraspecific taxa is recognized: subsp. vitaliana (Pyrenees), subsp. cinerea (south-western Alps), subsp. lepontina (Pennine Alps), subsp. sesleri (south-eastern Alps), subsp. praetutiana (Apennines) and subsp. assoana (Iberian Peninsula excluding the Pyrenees), the last of which is divided into the four allopatrically distributed varieties assoana, centriberica, flosjugorum and nevadensis. Contrary to some previous assertions, all taxa are allopatric and, especially for subspp. vitaliana, cinerea and lepontina, where clear diagnostic characters are lacking, they can best be determined by their geographic origin.

Dataset of MIGRAME Project (Global Change, Altitudinal Range Shift and Colonization of Degraded Habitats in Mediterranean Mountains) https://phytokeys.pensoft.net/article/5482/ PhytoKeys 56: 61-81

DOI: 10.3897/phytokeys.56.5482

Authors: Antonio Jesús Pérez-Luque, Regino Zamora, Francisco Javier Bonet, Ramón Pérez-Pérez

Abstract: In this data paper, we describe the dataset of the Global Change, Altitudinal Range Shift and Colonization of Degraded Habitats in Mediterranean Mountains (MIGRAME) project, which aims to assess the capacity of altitudinal migration and colonization of marginal habitats by Quercus pyrenaica Willd. forests in Sierra Nevada (southern Spain) considering two global-change drivers: temperature increase and land-use changes. The dataset includes information of the forest structure (diameter size, tree height, and abundance) of the Quercus pyrenaica ecosystem in Sierra Nevada obtained from 199 transects sampled at the treeline ecotone, mature forest, and marginal habitats (abandoned cropland and pine plantations). A total of 3839 occurrence records were collected and 5751 measurements recorded. The dataset is included in the Sierra Nevada Global-Change Observatory (OBSNEV), a long-term research project designed to compile socio-ecological information on the major ecosystem types in order to identify the impacts of global change in this mountain range.

DOI: 10.3897/phytokeys.46.9116

Authors: Antonio Jesús Pérez-Luque, Cristina Patricia Sánchez-Rojas, Regino Zamora, Ramón Pérez-Pérez, Francisco Javier Bonet

Abstract: Sierra Nevada mountain range (southern Spain) hosts a high number of endemic plant species, being one of the most important biodiversity hotspots in the Mediterranean basin. The high-mountain meadow ecosystems (borreguiles) harbour a large number of endemic and threatened plant species. In this data paper, we describe a dataset of the flora inhabiting this threatened ecosystem in this Mediterranean mountain. The dataset includes occurrence data for flora collected in those ecosystems in two periods: 1988–1990 and 2009–2013. A total of 11002 records of occurrences belonging to 19 orders, 28 families 52 genera were collected. 73 taxa were recorded with 29 threatened taxa. We also included data of cover-abundance and phenology attributes for the records. The dataset is included in the Sierra Nevada Global-Change Observatory (OBSNEV), a long-term research project designed to compile socio-ecological information on the major ecosystem types in order to identify the impacts of global change in this area.

URJC GB dataset: Community-based seed bank of Mediterranean high-mountain and semi-arid plant species at Universidad Rey Juan Carlos (Spain) https://phytokeys.pensoft.net/article/1515/ PhytoKeys 35: 57-72

DOI: 10.3897/phytokeys.35.6746

Authors: Patricia Alonso, Jose Maria Iriondo

Abstract: The Germplasm Bank of Universidad Rey Juan Carlos was created in 2008 and currently holds 235 accessions and 96 species. This bank focuses on the conservation of wild-plant communities and aims to conserve ex situ a representative sample of the plant biodiversity present in a habitat, emphasizing priority ecosystems identified by the Habitats Directive. It is also used to store plant material for research and teaching purposes. The collection consists of three subcollections, two representative of typical habitats in the center of the Iberian Peninsula: high-mountain pastures (psicroxerophylous pastures) and semi-arid habitats (gypsophylic steppes), and a third representative of the genus Lupinus. The high-mountain subcollection currently holds 153 accessions (63 species), the semi-arid subcollection has 76 accessions (29 species,) and the Lupinus subcollection has 6 accessions (4 species). All accessions are stored in a freezer at -18 °C in Kilner jars with silica gel. The Germplasm Bank of Universidad Rey Juan Carlos follows a quality control protocol which describes the workflow performed with seeds from seed collection to storage. All collectors are members of research groups with great experience in species identification. Herbarium specimens associated with seed accessions are preserved and 63% of the records have been georreferenced with GPS and radio points. The dataset provides unique information concerning the location of populations of plant species that form part of the psicroxerophylous pastures and gypsophylic steppes of Central Spain as well as populations of genus Lupinus in the Iberian Peninsula. It also provides relevant information concerning mean seed weight and seed germination values under specific incubation conditions. This dataset has already been used by researchers of the Area of Biodiversity and Conservation of URJC as a source of information for the design and implementation of experimental designs in these plant communities. Since they are all active subcollections in continuous growth, data is updated regularly every six months and the latest version can be accessed through the GBIF data portal at http://www.gbif.es:8080/ipt/resource.do?r=germoplasma-urjc. This paper describes the URJC Germplasm Bank and its associated dataset with the aim of disseminating the dataset and explaining how it was derived.

Sinfonevada: Dataset of Floristic diversity in Sierra Nevada forests (SE Spain) https://phytokeys.pensoft.net/article/1519/ PhytoKeys 35: 1-15

DOI: 10.3897/phytokeys.35.6363

Authors: Antonio Jesús Pérez-Luque, Francisco Javier Bonet, Ramón Pérez-Pérez, Rut Aspizua, Juan Lorite, Regino Zamora

Abstract: The Sinfonevada database is a forest inventory that contains information on the forest ecosystem in the Sierra Nevada mountains (SE Spain). The Sinfonevada dataset contains more than 7,500 occurrence records belonging to 270 taxa (24 of these threatened) from floristic inventories of the Sinfonevada Forest inventory. Expert field workers collected the information. The whole dataset underwent a quality control by botanists with broad expertise in Sierra Nevada flora. This floristic inventory was created to gather useful information for the proper management of Pinus plantations in Sierra Nevada. This is the only dataset that shows a comprehensive view of the forest flora in Sierra Nevada. This is the reason why it is being used to assess the biodiversity in the very dense pine plantations on this massif. With this dataset, managers have improved their ability to decide where to apply forest treatments in order to avoid biodiversity loss. The dataset forms part of the Sierra Nevada Global Change Observatory (OBSNEV), a long-term research project designed to compile socio-ecological information on the major ecosystem types in order to identify the impacts of global change in this area.

Herbarium of the University of Malaga (Spain): Vascular Plants Collection https://phytokeys.pensoft.net/article/1485/ PhytoKeys 26: 7-19

DOI: 10.3897/phytokeys.26.5396

Authors: Jose García Sánchez, Baltasar Cabezudo

Abstract: The herbarium of University of Málaga (MGC Herbarium) is formed by four biological collections. The vascular plants collection (MGC-Cormof) is the main collection of the herbarium. MGC-Cormof dataset aims to digitize and publish data associated with over 76.000 specimens deposited in the collection, of which 97.2% of the specimens are identified at species level. Since 2011, the University of Malaga’s Central Research Service (SCAI) has been responsible for maintaining the herbariums and the dataset. The collection is growing continuously, with an annual intake of about 1.500 specimens. Nearly 96% of the collection is digitized, by Herbar v3.7.1 software (F. Pando et al. 1996–2011), making over 73.000 specimens accessible through the GBIF network (http://data.gbif.org/datasets/resource/8105/). At present, 247 families and 8.110 taxa, distributed in angiosperms (93.97%), ferns and fern allies (4.89%) and gymnosperms (1.14%), constitute the MGC-Cormof collection. The families and genera best represented in the collection are Compositae, Leguminosae, Gramineae, Labiatae, Caryophyllaceae, Teucrium, Silene, Asplenium, Linaria and Quercus. Most of the specimens are from the Western Mediterranean Region, fundamentally Southern Spain (Andalusia: 82% of specimens) and Northern Morocco (2.17%). Approximately, 63% of the specimens are georeferenced. The identification of the specimens in the collection has been carried out by the plant biology department at the University of Malaga and plus 40% of the specimens has been reviewed by experts. The MGC-Cormof dataset has been revised by DarwinTest v3.2 tool (Ortega-Maqueda and Pando 2008) before being published in GBIF. The data included in this database are important for conservation works, taxonomy, flora, cartography, phenology, palynology, among others.El Herbario de la Universidad de Málaga (Herbario MGC) está constituido por cuatro colecciones biológicas.
