Chromosome numbers were determined in ten accessions of Phlomis olivieri Benth. (Lamiaceae). The seeds were collected from natural habitats in the west of Iran. Chromosome numbers of all accessions were 2n=2x=20. The chromosomes of accessions were metacentric or submetacentric, ranging in length from 2.66 to 8.604 μm. According to the average values of ten accessions, the karyotype of this species consists of 10 pairs of metacentric chromosomes. An ideogram was depicted for the species. This is the first report on the chromosome number and karyotype analysis of P. olivieri from Iran. © 2018 University of Zagreb. All arights reserved.

Drymocallis damghanensis Naderi and Faghir (Rosaceae) is described as a new species. The specimens were collected during a floristic study of an unexplored area on the rocky slopes of the Eastern Alborz Mountains (Damghan, Iran). Drymocallis damghanensis can be distinguished by its hairy carpels and rounded-obtuse teeth in leaflets. Here it is compared with the morphologically most closest taxa D. poteriifolia and D. schiraziana. © 2017 Finnish Zoological and Botanical Publishing Board.

The present study was conducted to analyze the phylogenetic status of the genus Onobrychis and to evaluate the monophyly of its subgenera and sections and relationship among them. We sequenced the nuclear ribosomal DNA internal transcribed spacer (nrDNA ITS) and three chloroplast regions trnL-F, rpl32/rpl32-trnL(UAG) and ndhF-rlp32 for phylogenetic reconstruction of 51 species of Onobrychis. In all of our analyses, Eversmannia subspinosa, Corethrodendron scoparium, Greuteria membranacea and G. argyrea were chosen as outgroups. Phylogenetic analyses were performed by maximum parsimony, maximum likelihood and Bayesian methods. Our molecular data indicate that Onobrychis is monophyletic and composed of two main clades, each corresponding to the redefined subgenus Onobrychis (including sections Onobrychis and Hemicyclobrychis) and subgenus Sisyrosema (including sections Afghanicae, Laxiflorae, Heliobrychis, Hymenobrychis, Insignes, Lipskyanae and Litvinovianae), respectively. Sections Lipskyanae and Litvinovianae are newly established and described, representing distinct lineages within the genus. Onobrychis splendida, a species hitherto without a sectional position, along with some members of sect. Anthyllium were retrieved representatives of section Lipskyanae. Sections Afghanicae, Insignes, Heliobrychis and Hymenobrychis (with the inclusion of two species of section Anthyllium) are monophyletic. Sections Dendrobrychis and Lophobrychis are reduced to synonymy of section Onobrychis and Anthyllium to synonymy of section Hymenobrychis. A taxonomic treatment for the genus is presented. © 2016, Springer-Verlag Wien.

The present study is a comprehensive taxonomic revision of the genus Bromus (Poaceae) in Iran. Based on the examination of 1500 herbarium specimens from Iran, 285 from neighboring countries and 30 type specimens, some nomenclatural modifications and classification changes are made. The tribe Bromeae for Iran was previously recognized as including the genera Bromus (29 species) and Boissiera (one species). Here, the number Bromus species in Iran is increased to 45. The Iranian taxa of the tribe Bromeae comprise the genus Bromus with 6 sections, 39 species and 40 taxa (two subspecies), including the cultivated B. catharticus, B. inermis and B. pumilio (synonym Boissiera squarrosa). Bromus rechingeri, B. pseudojaponicus and Bromopsis gabrielianae are reduced to synonymy. An identification key and detailed information of the geographical distribution of all treated species is provided. © 2015 Finnish Zoological and Botanical Publishing Board.

During work on a new synopsis on the genus Bromus L. for the 'Flora Iranica' region, an Afghan perennial brome grass previously identified as the Caucasian B. biebersteinii Roem. & Schult., was found to be a new species. It is described here as B. salangensis sp. nov. This discovery rejected the record of B. biebersteinii for Afghanistan. © 2013 Nordic Society Oikos.
