Critical species inventories provide primary biodiversity data crucial for biogeographical, ecological, and conservation studies. After six years, a second update to the inventory of vascular flora native Italy is presented. It provides details on occurrence at regional level and, first time, floristic San Marino. The checklist includes 8,241 subspecies, distributed in 1,111 genera 153 families; 23 taxa are lycophytes, 108 ferns fern allies, 30 gymnosperms, 8,080 angiosperms. species/subspecies endemic 1,702, grouped 71 families 312 genera. currently occurring 7,591, while 545 have not been confirmed recent times, 94 doubtfully country, 11 deficient, 236 reported by mistake be excluded national level.

The distribution of Parapholis strigosa (Dumort.) C.E.Hubb. in the Adriatic basin has been analysed. After investigations by Hylander and Runemark, further collections were made, particularly during years 1991-2002, 2017-2018 limited to Albania, that revealed presence an important population over entire basin, which was especially dense along northwestern coasts. These studies, together with revision historical material gathered from area conserved various Italian foreign herbaria, highlighted a quantitative morphological character clearly genetic origin, already considered as diagnostic within genus. This trait, anther length, falls into two distinct size classes, their values constant different areas turn characterised geological climatic situations.

Abstract Defining species boundaries within plant groups distributed along wide elevational and geographic gradients may lead to unstable taxonomic delimitations using morphological data only. Within the taxonomically challenging genus Dianthus , through an integrative approach we tested value of D. brachycalyx a putative endemic mountain peaks central‐southern Apennines, with respect widespread central‐Mediterranean virgineus . We measured 30 characters in 452 individuals from 25 populations obtained 3202 single nucleotide polymorphisms ddRAD‐seq techniques 394 36 populations. For climatic niche comparison, built dataset 348 occurrence points. By comparing morphometric, genetic, data, showed that cannot be considered distinct species. Morphometric separation between two is detectable, but high‐elevation are similar Genetic analyses revealed genetic structure mainly shaped by isolation‐by‐distance, irrespective their attribution. The niches overlapping, differences just due different availability conditions ranges. Accordingly, multiple lines evidence do not support former should heterotypic synonym latter.

By relating genetic divergence at neutral loci, phenotypic variation, and geographic environmental distances, it is possible to dissect micro-evolutionary scenarios involving natural selection evolution. In this work, we tested the patterns of intraspecific variation along an elevational gradient, using Dianthus virgineus as study system. We genotyped genome-wide SNPs through ddRAD sequencing quantified multivariate morphological variation. assessed by testing statistical association between genetic, phenotypic, geographic, distances explored role drift comparing Fst Pst morphometric traits. revealed a weak structure related distance among populations, but excluded predominant acting on A high degree differentiation with respect loci allowed us hypothesize effect selection, putatively fuelled changing conditions different sites, Thus, despite low can be hypothesized putative driver explaining observed

Within a practical course of cytotaxonomy organized in Pisa (Italy) on February 2024 by the Group for Floristics, Systematics and Evolution Italian Botanical Society, we tested whether using image analysis softwares possible biases are still introduced different observers. We conclude that observer bias selectively applies possibly overestimating length short arms karyotype. As consequence, parameters most sensitive to these errors CV CI CL , less degree M CA THL. To achieve more stable results among observers, lacking standardized measurement protocol could be helpful.
