BACKGROUND AND AIMS Tribe Arabideae are the most species-rich monophyletic lineage in Brassicaceae. More than 500 species are distributed in the majority of mountain and alpine regions worldwide. This study provides the first comprehensive phylogenetic analysis for the species assemblage and tests for association of trait and characters, providing the first explanations for the enormous species...

The steppe parts of Lissar protected area is located in the North Western part of Talesh mountain range, with an area around 13,500 hectares. The area is influenced by a humidCaspian climate at the Eastern slope and a cold mountain Irano-Turanian-like climate at the Western slope causing the formation of diverse vegetation types. Based on a collection of about 1,250 specimens during 2007–08, a ...

BACKGROUND AND AIMS The genus Centaurea has traditionally been considered to be a complicated taxon. No attempt at phylogenetic reconstruction has been made since recent revisions in circumscription, and previous reconstructions did not include a good representation of species. A new molecular survey is thus needed. METHODS Phylogenetic analyses were conducted using sequences of the internal ...

La section Melanocrommyum Webb & Berthel. du genre Allium L., de barycentre irano-anatolien, a longtemps été considérée sous une seule espèce en Europe l'ouest et au Maghreb, à savoir la messicole archéophyte nigrum L.. découverte d'Allium cyrilli Ten. Algérie vient confirmer coexistence des deux espèces comme cela récemment mis évidence France Espagne. Nous donnons comparaison détaillée illust...

The distribution patterns of taxa belonging to the section Hypoglottidei DC. were investigated using DIVA-GIS software. Based on Zohary classification, five global patterns, with the exception of widely distributed species, include 1. Centro-Asiatic province, 2. Irano-Anatolian province, 3. Pontic province, 4. East Mediterranean subregion and 5. West Mediterranean subregion, were identified. In...
