Anthemissect.Hiorthia (Asteraceae) on Kriti Island, Greece: high ploidy levels and a new species.

A morphological and karyological investigation of the Anthemissect.Hiorthia representatives of Kriti (Greece) revealed that three different species are found on the island, all endemic, and each characterised by a different ploidy level based on the haploid series of = 9. , the species with the widest distribution, is tetraploid with 2 = 4 = 36.

Stomata in Close Contact: The Case of L. (Amaryllidaceae).

A special feature found in Amaryllidaceae is that some guard cells of the neighboring stomata form a "connection strand" between their dorsal cell walls. In the present work, this strand was studied in terms of both its composition and its effect on the morphology and function of the stomata in L. leaves.

A Morphometric and Karyological Study of the Group (Asteraceae, Anthemideae) Reveals a New Species from Greece.

A recent study of the collections in the Balkans indicated that the taxa of the group ( subsp. , subsp. , , ) exhibit noteworthy morphological patterns not evaluated before.

Plant Diversity of Mts. Oligirtos and Farmakas (NE Peloponnisos, Greece) with Emphasis on Their Endemic Flora.

Greece is known to be a biodiversity hotspot. Though the plant diversity of Peloponnisos, the southernmost part of the Greek mainland, has been well-studied during the past 200 years, there are still gaps in our knowledge. To this end, the flora of the neighboring mountains Oligirtos and Farmakas was investigated, with a total of 740 and 762 taxa (species and subspecies) recorded, respectively, of which 635 and 756 for the first time.

Thirty-two new and noteworthy floristic records from north-eastern Greece.

Background: The vascular flora of Greece comprises no less than 6,705 vascular plant taxa (species and subspecies, including established aliens) in an area of 131,957 km. The phytogeographic region of north-east Greece (NE), an area characterised by physiographic diversity, is the richest floristic region in Greece, yet it remains less-explored compared to other regions.

New Information: We present an annotated inventory of 32 vascular plant taxa collected predominantly from the East Macedonia and Thrace Regions (Makedonia and Thraki, NE Greece), following fieldwork that took place between 2013 and 2021.

What Socrates drank? Comparative chemical investigation of two Greek Conium taxa exhibiting diverse chemical profiles.

Conium divaricatum, even though exhibiting morphological differences in comparison to its congener of European origin Conium maculatum, is still considered a disputed taxon often referred to as a synonym of the latter. Herein, essential oils of various plant tissues from several populations of both taxa were comparatively investigated, showing distinct chemical profiles. In the case of C.

Mountains and refuges: Genetic structure and evolutionary history in closely related, endemic Centaurea in continental Greece.

Mountains of continental Greece are one of the main Mediterranean biodiversity hotspots, very rich in endemic species. The speciation in this area might have resulted from two main factors: a complex orography and its role as a refugium during past glaciations. We have investigated genetic diversity and population structure for a group of narrow endemics of Centaurea subsect.

Phylogeny of the Centaurea group (Centaurea, Compositae) - geography is a better predictor than morphology.

The Centaurea group is part of the Circum-Mediterranean Clade (CMC) of genus Centaurea subgenus Centaurea, a mainly Mediterranean plant group with more than 200 described species. The group is traditionally split on morphological basis into three sections: Centaurea, Phalolepis and Willkommia. This division, however, is doubtful, especially in light of molecular approaches.

Volatile compounds in Thymus sect. Teucrioides (Lamiaceae): intraspecific and interspecific diversity, chemotaxonomic significance and exploitation potential.

Thymus sect. Teucrioides comprises three species, namely, T. hartvigii, T.
