“…However, some characters induced many researchers to consider P. crystallina and P. hirtiflora two different species (Degtjareva et al 2004;Degtjareva et al 2006;Peruzzi 2006;Peruzzi 2007;De Castro et al data unpublished), even if Casper et al (2007) prefer to use the expression P. crystallina-hirtiflora aggregate. The two species, P. hirtiflora and P. crystallina, belong to the section Cariophyllum within the subgenus Isoloba, along with the endemics P. habilii Yildirim Şenol & Pirhan present in Turkey (Yıldırım et al, 2012) and the newly discovered P. lavalvae Innangi & Izzo growing in southern Italy (Innangi & Izzo 2014). Pinguicola hirtiflora presents an interesting distribution: most of its populations occur in Albania, Greece and Turkey, while a few are located in southern Italy, especially in the regions Campania and Calabria (Innangi et al 2011).…”

2014): Rare species habitat suitability assessment and reliability evaluation of an expert-based model: a case study of the insectivorous plant Pinguicula crystallina Sibth. et Smith subsp. hirtiflora (Ten.) Strid (Lentibulariaceae), Rare species habitat suitability assessment and reliability evaluation of an expert-based model: a case study of the insectivorous plant Pinguicula crystallina Sibth. et Smith subsp. hirtiflora (Ten.) Strid (Lentibulariaceae). AbstractThe development of habitat suitability models requires a large amount of data which is rarely available. In this case, researchers need to get information on the ecological features of the studied species, based on the opinion of experts or on literature, to construct a qualitative model. However, such models cannot be rigorously evaluated, as in most cases absence points are not available. In this paper, we assess the habitat suitability for a vulnerable insectivorous plant, Pinguicula crystallina Sibth. et Smith subsp. hirtiflora (Ten.) Strid (Lentibulariaceae) in the Campania region. Our aim was to develop an expert-based, presence-only model in support of possible conservation actions. Topographic and geological features of this species suggested by the literature were used in our model. Both the Boyce index and field surveys were chosen to evaluate the model's reliability. During field surveys, 31 absence sites and 1 new presence site were identified, and differences between sites with regard to water chemistry and quality were investigated, being water a element in the species habitat. Factors that affect reliability of the model, such as the lack of a large amount of information on the species and the limited spatial resolution of GIS data, are discussed.

“…We used generalized procrustes analysis (GPA) as a superimposition method, considering the objects as symmetric [82]. GPA is an established procedure for analysis of 2D and 3D shapes, which has been widely applied to plants in the last years [83][84][85][86][87][88]. Although objects such as leaves can be analyzed also by means of elliptical Fourier analysis [89], we decided that a landmark approach was more suited to detect possible subtle changes with potential diagnostic value, such as those considering the morphology of leaf apex.…”

Globularia is a genus of small evergreen and perennial shrubs that are widespread in Europe. Globularia section Empetron includes a group of three species, G. cordifolia, G. meridionalis, and G. neapolitana, that have been taxonomically disputed for more than 150 years. Many morphological features have been proposed to discriminate these species. Nevertheless, evidence from both past and recent literature suggest that these differences among species are not consistent. In order to shed new light in this long-disputed group, we investigated 10 populations of the G. cordifolia species complex with both classical and geometric morphometrics and used environmental predictors in multivariate regression to explain patterns of variation. Our results showed that bract area and calyx teeth length are correlated with solar radiation and annual precipitation, whereas leaf dry mass per unit area can be explained by temperature seasonality. Leaf shape can be explained by temperature seasonality as well, although with a lower amount of explanatory and predictive power. Despite a comparatively low sample size in terms of populations, our results were based on a large number of individuals and were supported by a robust statistical approach. We can conclude that differences among the three species of Globularia could be related to the combined effects of several ecological variables and might not have taxonomical value. Our novel approach provided an ecological interpretation on a species complex that makes up a continuum of forms within the environmental framework of the Mediterranean basin.

Disentangling Phylogenetic Relationships in a Hotspot of Diversity: The Butterworts (Pinguicula L., Lentibulariaceae) Endemic to Italy

The genus Pinguicula (Lentibulariaceae) consists of about 100 carnivorous species, also known as butterworts. Eleven taxa are endemic to Italy, which represents a biodiversity hotspot for butterworts in Europe. The aim of our study was to provide a phylogenetic framework for the Italian endemics, in order to: a) investigate the relationships between species in this group; b) evaluate their actual taxonomic value. To achieve this, we analysed all the taxa endemic to Italy, along with several other species, by means of ITS nrDNA analysis. Our results clarify the relationships between Italian endemics and other Pinguicula taxa identifying a basal polytomy defined by five clades. All of the Italian endemics (with the exception of P. lavalvae) fall within a single large clade, which includes P. vulgaris and allied species. Among them, P. poldinii represents the most isolated lineage. Other taxa show strong molecular similarities and form a single subclade, although their taxonomic ranks can be retained. Pinguicula lattanziae sp. nov., seemingly endemic to Liguria (NW Italy), is also described.
