This is a preprint page for a manuscript under review that was accidentally uploaded to a preprint platform from which it has already been removed. We are trying to remove it from ResearchGate.
Micromeria silicii, a new species from St. Andrea (Svetac) and Biševo Islands of Dalmatia (Croatia) is described and illustrated. Previously, it was attributed to M. microphylla, but careful morphological investigation allowed to differentiate it from the latter. In order to emphasize the relationships with the other taxa currentelly attributed to...
Cryptogams, often overlooked spore-producing organisms, have a complex
taxonomy and generally small size, making their identification and
distribution challenging to understand. The Balearic Islands only have some
scattered data about cryptogams. The "Cryptogams of the Balearic Islands
(CBI)" dataset aims to bring this data together through extensi...
The Atlas of the vascular flora of the Iberian Peninsula (AFLIBER) compiles distribution information for all native vascular plants in the Iberian Peninsula and the Balearic archipelago. AFLIBER stands as the new standard reference for Iberian vascular plants, being the most exhaustive and updated high-resolution database available to date, with 1,...
Migratory insects may move in large numbers, even surpassing migratory vertebrates in biomass. Long-distance migratory insects complete annual cycles through multiple generations, with each generation’s reproductive success linked to the resources available at different breeding grounds. Climatic anomalies in these grounds are presumed to trigger r...
Our understanding on the role of introduction pathways on plant invasions is incomplete because their interaction with other factors remains poorly studied. We contributed to filling this knowledge gap, by analysing temporal trends in pathway importance, pathway-specific differences in the invaded niche, and the effect of pathways on invasion succe...
Sideritis royoi is found in the rocky limestone habitats of the Port Massif (southern Catalonia, Spain). The species was first collected by the local botanist Lluís de Torres in the late part of the 20th century, but the specimens have remained unidentified positively in herbaria for over 40 years. Sideritis royoi likely belongs to section Sideriti...
A nomenclatural revision of the names published under the genus Santolina (Anthemideae) from Iberian Peninsula and northern Africa is presented. The nomenclature of 34 names is discussed. Previous typifications are critically revised, and ten types are designated in this study: six of them fix the application of currently accepted names (Santolina...
This work presents a comprehensive catalogue of the bryophyte flora of the Cadí-Moixeró Natural Park, based mainly on the collection campaigns conducted between 2016 and 2022. During this period, 1,118 bryophyte samples were collected in the 53 localities surveyed. The resulting bryophyte list is supplemented by previous literature reports and unpu...

The Irano-Turanian region is one of the world’s richest floristic regions and the centre of diversity for numerous xerophytic plant lineages. However, we still have limited knowledge on the timing of evolution and biogeographic history of its flora, and potential drivers of diversification remain underexplored. To fill this knowledge gap, we focus...
Santolina is a clear example of a genus lying in an alpha-taxonomic status, with species accepted only based on qualitative morphological descriptions. In particular, taxonomic issues still need to be resolved for Santolina populations from southern France and north-eastern Spain, so that we carried out an integrative taxonomic study involving morp...
The Mediterranean islands are exceptionally rich in endemism, most of which is narrowly distributed. Conservation measures, such as protected areas, have been prioritised, mainly on the basis of species richness and endemism, but phylogenetic information should also be taken into account. In this study, we calculated several taxonomic and phylogene...
Linaria sagrensis , from the south‐eastern Iberian Peninsula, is here newly described, illustrated, and compared with its morphologically closest relatives from L. sect. Supinae : L. pruinosa , L. nevadensis , L. glacialis and L. alpina subsp. alpina . The species is characterized by being perennial, entirely glandular‐hairy, with inflorescence den...
In this contribution, new data concerning the distribution of native vascular flora in Italy are presented. It includes new records, confirmations, and exclusions to the Italian administrative regions. New combinations in the genera Pilosella and Roemeria are proposed. Furthermore, the name Papaver siculum is lectotypified. Nomenclatural and distri...

The typification of the name Hippocrepis balearica is discussed. The name is lectotypified on an illustration published by Jacquin in 1781.
The genus Santolina (Asteraceae, Anthemideae) includes 26 species of aromatic evergreen shrubs endemic to the western Mediterranean Basin. Santolina is widely used as ornamental plant, in xerigardening, and in ethnobotany. The Santolina chamaecyparissus complex, including about half of the known species diversity, has been properly investigated on...
A traditional karyomorphological approach was carried out in order to investigate the cytotaxonomic relationships among the species of the Santolina chamaecyparissus complex. All the 14 species included in this species complex were analysed for a total of 39 populations. Metaphase plates were obtained by squashing root tips stained with Feulgen tec...
The typification of the names Ranunculus chaerophyllos var. balearicus and R. weyleri is discussed. These two names are lectotypified using specimens preserved at COI.
The name Hieracium loscosianum Scheele is lectotypified using a specimen preserved at COI herbarium.

For the conservation of species, it is crucial to predict extinction risk by discerning drivers such as biological traits and habitat specificity within the current context of environmental change. However, we lack comprehensive studies for threatened bryophytes that include comparisons to non-threatened ones. We aim to fill this gap and to detect...
Identity of the taxa of the Avena barbata complex (Poaceae) occurring in the Mediterranean region.
In this study, the taxa belonging to the Avena barbata complex are treated at species level, and five species occurring in the Mediterranean region are accepted. The lectotype designation for Avena barbata var. saxatilis is rejected, and a new combina...
Silene neglecta has been misunderstood and confused with S. nocturna, although several morphological characters (petal shape, calyx indumentum, hairiness of stamen filaments, seed size, seed-coat surface and shape) allow separation of the species. Moreover, S. mutabilis (which has been considered conspecific with S. neglecta) and S. martinolii (an...

The typification of the species names Santolina ericoides and S. villosa (Asteraceae) are revisited. The name Santolina ericoides has been applied to plants distributed in the Iberian Peninsula and S France, and the name S. villosa has been applied to a taxon endemic to Spain. These species names have recently been neotypified from specimens kept a...
Species diversity may be underestimated even in well-explored mountain regions due to the lack of in-depth research in taxonomically intricate groups. Filling such knowledge gap is necessary to optimize conservation management, specially for species occurring in vulnerable ecosystems such as Southern European mountains. Campanula sect. Heterophylla...
The names in Amaranthus described by Frère Sennen from Spain were studied and, when necessary, typified. Seventeen lectotypes, preserved in BC and MA herbaria, have been designated. Isolectotypes were traced at BCN, herb. Sennen II, JE, JBAG (herb. Laínz), K, MA, P, and PH.
Petrocoptis montsicciana and P. pardoi are two Iberian endemic taxa of Caryophyllaceae family with an unclear taxonomic delimitation, being variously treated as independent species, subspecies or even synonyms. In the present study, allozyme raw data obtained in the early 2000s have been reused with improved tools to survey genetic structure, and c...
Potentilla asturica, an Iberian endemic species included within sect. Recta, is typified.
The eastern Mediterranean basin hosts a remarkably high plant diversity. Historical connections between currently isolated areas across the Aegean region and long-distance dispersal events have been invoked to explain current distribution patterns of species. According to most recent treatments, at least two Cymbalaria species occur in this area, C...
