Two slow worm species are distributed at the southernmost part of the Balkan Peninsula: Anguis cephallonica, an endemic of the Peloponnese and the islands Zakynthos, Ithaki and Kephallonia, and A. graeca. Here, we investigate the intraspecific genetic diversity of A. cephallonica from the Peloponnese and Kephallonia and analyse A. graeca, from the northern Peloponnese, where it is found in sympatry with A. cephallonica. MtDNA and nDNA phylogenetic analyses confirm the genetic similarity of Peloponnesian and Kephallonian populations of A. cephallonica and reveal significant mtDNA genetic variation within it, probably related to the occurrence of multiple subrefugia in the Peloponnese. Peloponnesian A. graeca populations are genetically similar to non-Peloponnesian conspecifics implying recent dispersal to the Peloponnese. In contrast to the genetic markers, morphological characteristics (such as the number of mid-body scale-rows) failed to distinguish between Peloponnesian A. cephallonica and A. graeca. Although the former species is believed to be well-differentiated from its congeneric taxa, a thorough morphological study is needed.

Trifolium multistriatum (T. sect. Vesicastrum subsect. Mystillus) is a neglected species currently considered as a synonym of T. setiferum or T. rumelicum. The identity of T. multistriatum compared to the species closely related is briefly discussed and its distinct autonomy is highlighted based on the analysis of relevant literature and herbarium specimens, including the type material. The holotype is indicated here for its name based on an exsiccatum belonging to the gathering cited in the protologue, which is preserved at L. Other relevant related material is preserved at PAD and TSM. The distribution area of T. multistriatum includes Western Balkan Peninsula and Italy. The studied material was mostly collected long time ago. For Southern Italian territory, the most recent records date back to the mid 1900s.

The coleorhiza is a nonvascular sheath that encloses the embryonic radicle in Poaceae, and is generally the first tissue to emerge during germination. Delicate hairlike extensions develop from some coleorhiza cells prior to radicle emergence. Similar to root hairs, coleorhiza hairs are extremely sensitive to desiccation and are damaged by exposure to negative water potentials. The coleorhiza of Lolium perenne is somewhat spherical when first visible, after which a knob forms at a right angle to the caryopsis due to inner pressure from the elongating radicle. This knob increases in length until the radicle finally punctures the coleorhiza. Standard fixation procedures cause severe desiccation of coleorhiza cells and hairs, making morphological study of the coleorhiza difficult. This study was conducted to determine a more successful process for coleorhiza preservation.
