Summary: This study examined the pollen morphology of different varieties of Paeonia lactiflora and found that the pollen grains were spherical or subspherical in shape with tricolporate apertures. The exine sculpture of the pollen grains varied between reticular and pit type. The differences between the varieties were mainly observed in the exine sculpture. The morphological characteristics of the herbaceous peony pollen were correlated with the shapes of flower and scale buds and the texture of the petals.

Summary: Pollen morphology of 34 herbarium specimens from 17 taxa of the genus Valeriana was studied, revealing four types and eight subtypes of exine sculpture. The study concluded that palynomorphological data can aid in species-specific identification and support molecular phylogenetic studies. The close phylogenetic relationships among certain Valeriana species were also supported by palynomorphological characters, particularly exine sculpture.

Summary: This study analyzed the palynomorphological features of Symphoricarpos and compared them with taxonomic classification scheme and molecular phylogenetic data. The results showed that pollen morphology, including size, details of colpi and ores, presence/absence and width of annuli, and exine sculpture, are important diagnostic features for the taxonomy of Symphoricarpos. The study also suggested an evolutionary trend towards a decrease in the size and number of echini and microechini in the exine sculpture.

Summary: Molecular phylogenetic studies have identified a parasitic Boschniakia-Epifagus clade within Orobanchaceae. This study examines the pollen morphology of seven species belonging to five genera using both light and scanning electron microscopy. The results show that the pollen grains exhibit morphological diversity and can be distinguished at the genus and species levels based on features such as shape, size, colpi length and width, exine thickness and sculpture.

Summary: The palynomorphological features of four plants of Anemone genus collected in different areas of Elbasan region show variations in aperture and sculpture of exine, with Anemone apennina having the smallest pollen grains and Anemone hortensis having the thickest exine among the studied plants.

Summary: This study conducted a comparative palynological study of Dipsacaceae s.str., revealing diverse pollen grain morphologies in its representatives. Analysis of the pollen morphology of selected taxa such as P. plumosus, S. pratensis, and S. inflexa provided new insights into their relationships based on palynomorphological data.

Summary: Phylogeographic and evolutionary studies are crucial for establishing taxonomic treatments and conservation programs. The taxonomic framework for some Mediterranean taxa, such as the Arenaria section Pseudomoehringia, is still lacking. Through analyses of nuclear and plastid DNA markers, the study confirmed the monophyly of the section and identified two species while supporting an additional species complex. The phylogeographic results suggest dispersal from the Iberian Peninsula to North Africa and indicate edaphic differentiation between closely related species.

Summary: The ecological drivers for genetic differentiation in Mediterranean climates were explored using the strictly Mediterranean endemic Odontites recordonii as a model species. Phylogenetic relationships within the O. vernus group were revealed using molecular markers, and phylogeographic patterns within O. recordonii were reconstructed. Temperature, precipitation seasonality, and summer drought were found to be influential climatic parameters driving genetic differentiation within O. recordonii.

Summary: The Odontites vernus group, the most widespread in the genus Odontites, is mainly distributed in temperate regions of Eurasia and northern Morocco. This study focused on the Iberian Peninsula, where O. vernus s.l. showed remarkable morphological variability and consisted of diploid and tetraploid individuals. By genotyping and flow cytometry, it was found that tetraploids likely originated through autopolyploidy. Genetic analysis revealed seven genetic groups, coinciding with known refugium areas during Quaternary climatic oscillations in the Iberian Peninsula.
