nonea medik. is a genus of the boraginaceae tribe boragineae, with approximately 35 species worldwide. examination of their palynological characters supported the separation of taxa, which is usually based on morphological and micromorphological reproductive features. pollen grains of 10 taxa representing three groups of taxa in iran, the n. caspica group, the n. persica group and the n. lutea ...

Hyla versicolor, a tetraploid treefrog, is reported to have originated via multiple hybridization events involving three diploid ancestors. Its complex reticulate history provides insights into the roles that polyploidy and hybridization can play in the origin of species.

This study was conducted for extensive and systemic investigation of anatomical, palynological seed morphological properties two endemic Noccaea species, naturally growing in Turkey. Independent sample T-test box plot were carried out using quantitative characters the studied species. The anatomical results showed that species had similar characteristics, though there significant differences ro...

Reticulated pigmentation is a unique pigmentary change caused by a heterogeneous group of hereditary and acquired disorders. This pigmentation is characterized by a mottled appearance, with lesions that vary in size and pigmentary content. This review discusses the hereditary group of the reticulated pigmentation disorders, such as dyschromatosis symmetrica hereditaria, dyschromatosis universal...

Focal dermal hypoplasia or Goltz syndrome is a rare genodermatosis involving all three embryonic layers. Herein, the first case of this syndrome from Iran will be reported. The main clinical features were fat herniation, reticulate pigmentations, telangiectasia, and skeletal defects.

In this work, morphological and anatomical features of seeds 15 Alyssum taxa (A. caricum, A. davisianum, filiforme, haussknechtii, murale subsp. var. murale, simplex, sibiricum, desertorum, hirsutum hirsutum, minutum, strictum, strigosum strigosum, szowitsianum, dasycarpum linifolium linifolium) from Turkey were examined with the cluster analysis, systematic importance these characteristics was...

Dowling Degos disease is a rare condition inherited as autosomal dominant trait characterized by numerous, asymptomatic, symmetrical, progressive, small, round-pigmented macules over axillae and groins, face, neck, arms and trunk, scattered comedo-like lesions (dark dot follicles) and pitted acneiform scars. Histopathology is diagnostic. We are hereby reporting three cases of Dowling Degos dise...

In Siberia, the bluegrass genus (Poa) comprises 43 species and 61 subspecies in 12 sections. Diverse modes of speciation, including polyploidy and hybridization, have led to reticulate evolution and adaptive radiation. Cladistic methods that ignore hybridization and reticulate evolution may not be appropriate for morphological data. The number of morphological characters suitable for bluegrass ...
