Taxonomic study of the genus Padina (Dictyotales, Phaeophyceae) from the Persian Gulf coast was conducted based on morphology and molecular phylogenetic analyses using chloroplast encoded large subunit RuBisCo (rbcL) gene sequences. Detailed descriptions of each species found in this study are described. Several morphological characters, such as number of cell layers composing the thallus, pr...

The genus Phyllactinia is one of the members of Erysiphaceae (Erysiphales, Ascomycota) which parasitize several host plant families. This taxon is well characterized by having acicular appendages with bulbous swelling at the base and penicillate cells which are outgrowth of some ascoma wall cells. A number of challenges exist to distinguish species assigned to this taxon. This is because of a f...

Noticeable variation was observed in a number of morphological characters in the Glycyrrhiza specimens in various habitats in north of Iran. To study these variations, two taxa related to the Hyrcanian region from all four known taxa of this genus in Iran, including Glycyrrhiza echinata, and G. glabra var. glabra were studied by numerical taxonomy using morphological characters in three provinc...

This study describes morphological diversity and relationship of 14 cultivars and 133 wild fig accessions from central Zagros Mountains located in the west of Iran, based on 58 morphological characters. Among all characters, secondary drooping branches, number of bark tubers, shape of central lobe, length of central lobe/length of lamina, little lateral lobes, shape of leaf without lobed, fruit...

Wyeomyia exallos, a new mosquito species from Atlantic Forest of southeastern Brazil, is described based on morphological characters of the adult female, male, male genitalia, pupa and fourth-instar larva. The morphological characters of Wy. exallos sp. nov. are compared with those of different subgenera of Wyeomyia as well as of species without subgeneric position. It is proposed that the new ...

Certain species of bumblebees are difficult to distinguish based on morphology alone due to a lack of diagnostic characters and extensive intraspecific variation in colour patterns. The discussion concerning whether Bombus lapponicus and Bombus monticola are the same species or not, seems to be ongoing. We present a study of 16 speciemens of B. monticola/B. lapponicus from Norway, identified wi...
