The European Vegetation Archive (EVA) is a centralized database of European vegetation plots developed by the IAVS Working Group European Vegetation Survey. It has been in development since 2012 and first made available for use in research projects in 2014. It stores copies of national and regional vegetation- plot databases on a single software platform. Data storage in EVA does not affect on-going independent development of the contributing databases, which remain the property of the data contributors. EVA uses a prototype of the database management software TURBOVEG 3 developed for joint management of multiple databases that use different species lists. This is facilitated by the SynBioSys Taxon Database, a system of taxon names and concepts used in the individual European databases and their corresponding names on a unified list of European flora. TURBOVEG 3 also includes procedures for handling data requests, selections and provisions according to the approved EVA Data Property and Governance Rules. By 30 June 2015, 61 databases from all European regions have joined EVA, contributing in total 1 027 376 vegetation plots, 82% of them with geographic coordinates, from 57 countries. EVA provides a unique data source for large-scale analyses of European vegetation diversity both for fundamental research and nature conservation applications.

We report on the occurrence of Orobanche krylowii in the Alpet Shqiptare (Prokletije, Albanian Alps) mountain range in northern Albania (Balkan Peninsula). The species was previously known only from eastern-most Europe (Volga-Kama River in Russia), more than 2500 km away, and from adjacent Siberia and Central Asia. We used morphological evidence as well as nuclear ribosomal ITS sequences to show that the Albanian population indeed belongs to O. krylowii and that its closest relative is the European O. lycoctoni, but not O. elatior as assumed in the past. Both Orobanche krylowii and O. lycoctoni parasitize Ranunculaceae (Thalictrum spp. and Aconitum lycoctonum, respectively). We provide an identification key and a taxonomic treatment for O. krylowii, and suggest the IUCN category CE (critically endangered) for the highly disjunct Albanian population. © 2013 Magnolia Press.

After carefully reviewing its protologue and lectotype, it is concluded that Orobanche foetida Poir. (1789) is an earlier synonym of Orobanche variegata Wallr. (1825) and cannot be used for the western Mediterranean species to which in recent times it has been generally applied. Unless the conservation of that concept of the binomen Orobanche foetida is proposed and approved, that Iberian and North African plant must be called Orobanche hookeriana Ball.

In this paper a neglected taxon of Orobanche s. str. is shown to deserve specific rank for combining a set of correlated morphological features and a particular host (Carlina). As it had already been validly named at varietal and subvarietal rank by J. A. Guimarães, it needn't be validly described, but is here typified, raised to the rank of species, thoroughly described, illustrated with detailed drawings and colour photographs and demonstrated to occur well beyond its terra classica not only in Portugal and Spain, but probably also in southern France, Corsica and Sicily. In addition, some morphological, chorological and iconographical additions to the knowledge of the recently described Orobanche subbaetica will be done.

Jiménez-Alfaro, B., Alonso Felpete, J.I., Bueno Sánchez, A. & Fernández Prieto, J.A. Alpine plant communities in the Picos de Europa calcareous massif (Northern Spain). Lazaroa 35: 67-105 (2014). Mountains of Southern Europe are important refuges for cold-adapted plants, and the characterization of vegetation diversity in these areas is a relevant topic for biodiversity conservation. Here we report a comprehensive classification of plant communities in the highest altitudinal belt of the Picos de Europa, a biodiversity hotspot of Northern Iberian Peninsula. We compiled vegetation plot data sampled in the three calcareous massifs from 1800 to 2600 m.a.s.l., and analysed species composition by using cluster analyses and Nonmetric Multidimensional Scaling (NMDS). Optimal classification and the interpretation of multivariate analyses allowed us to recognize two major vegetation types and six clusters that were characterized by their floristic composition, altitudinal range and phytosociological classification. The first vegetation type (alliance Festucion burnatii, class Festuco hystricis-Ononidetea) corresponds to stripped habitats subjected to cryoturbation and represented by two community types (Helianthemo cantabrici-Festucetum hystricis ass. nova and Jasiono cavanillesii- Helictotrichetum sedenensis ass. nova). A second vegetation type includes alpine-like communities with higher biomass (alliance Armerion cantabricae, class Festuco-Seslerietea) represented by snow-bed (Ranunculo carinthiaco-Poetum alpinae ass. nova), mesophilous (ass. Pediculari fallacis-Armerietum cantabricae) and scree (Saxifrago coniferae-Helianthemetum urrielensis ass. nova) grasslands; and relict wind-edge swards (alliance Oxytropido-Elynion, class Carici rupestris-Kobresietea myosuroides) represented by relict alpine communities (ass. Oxytropido neglectae-Kobresietum myosuriodis). Our results highlight the Picos de Europa as a unique refuge for alpine vegetation and demonstrate historical relationships with both Alpine-Pyrenean and Iberian mountain ranges.

Holoparasites have evolved a number of adaptations for pollination in parallel with their parasitic strategies. Complex floral pigmentation patterns, comprising spots or stripes that act as visual nectar or landing guides for pollinators, are common and diversified, but their structure and function are poorly understood and almost nothing is known about the role that micromorphological features might play in generating or complementing those visual stimuli. By means of scanning electron and confocal digital microscopy, petal micromorphology was analysed in the two subspecies of the holoparasitic Cistanche phelypæa (subsp. phelypæa and subsp. lutea, Orobanchaceae). Plant material was collected in the semi-deserts of southeastern Spain in 2009 (subsp. lutea), and in coastal salt marshes in southern Portugal in 2012 (subsp. phelypæa). Cistanche phelypæa subspecies were already known to differ in several morphological features of flowers and leaves, as well as in their habitats and hosts. Our data have shown that they also differ in several micromorphological features of the petal epidermis. Three different sculpture types of the petal epidermis were recognized. Our results show that petal micromorphology can be used in the separation of taxa, with potential utility in the determination of dried specimens in this genus, inherently poorly preserved in herbaria. The putative influence of the visual and tactile effects originating from this micromorphological variability on the interactions between plants and pollinators and in the reproductive biology of the former is discussed in detail. © 2016 Societe botanique de France.
