Teucrium (Lamiaceae) is a large and polymorphic genus distributed mainly in Europe, North Africa and in the temperate parts of Asia. In this study, the anatomical features of the leaf and stem of Teucrium polium are investigated. Teucrium has 19 taxa in Iran, which mainly grow in the Irano-Turanian region between 700 and 2000 m above sea level. T. polium belonging to sect. Polium, is a perennia...

A forest area in Deh-Kohneh, the northwest of Fars Province, Iran was studied from a floristic and ecological point of view. The species were classified according to their growth habit. Raunkiaer’s life - forms systemwere used to characterize the flora of the study area. The location has a surface area of 466 ha by minimum altitude at 2100m and maximum at 2554m, between 30 ° 21΄ 32˝ to 30° 23΄ ...

Species identification is fundamentally important within the fields of biology, biogeography, ecology and conservation. The genus Alcea (Malvaceae) includes approximately 70 species mainly Irano-Turanian distribution considered one most challenging genera Middle East, due to its uniformity pronounced plasticity in morphological traits. In spite vast many that grow Iraq, there are not any availa...

Dianthus berkayii belongs to sect. Fimbriati was described and illustrated as a new species from Erzincan Province in Eastern Anatolia, Turkey. In the current study morphological, palynological, molecular characters were compared discussed with its closely related species. The is similar D. crinitus fimbriate corolla, linear, acuminate, ± rigid leaves. Also vanensis rigid, curved divaricate But...

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 ...

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 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...
