A new fossil conifer Araucaria rothwellii J.Kvaek from the Campanian-Maastrichtian marine sediments of the Bozova Formation in southeastern Turkey is described based on leaf compressions and leaf impressions. The new species is characterized by twigs possessing helically arranged broadly lanceolate leaves with attenuate apexes and slightly narrowed bases. Amphistomatic leaves bear stomata arranged in rows surrounded by four to six subsidiary cells; the rows are longitudinal to the leaf margin. Ordinary epidermal cells are elongately rhomboidal with straight or slightly undulate anticlinal walls. Comparisons with already published fossil species and recent species are provided. The new fossil species A. rothwellii is similar in macro- and micromorphology to extant A. bidwillii, which is indigenous to Queensland in northeast Australia.

Comparative molecular phylogenetics of Astragalus L. sections from Turkey with New World Astragalus species using nrDNA ITS sequences Dizkirici, Ayten; EKİCİ, MURAT; Kaya, Zeki (Springer Science and Business Media LLC, 2014-01-01) Comparative molecular phylogenetic study using nrDNA internal transcribed spacer region (ITS) sequences was carried out on species from three Astragalus L. (Fabaceae) sections from Turkey (Old World species) and the New World. A total of 56 taxa (179 accessions) including 30 species from Incani DC., 15 species from Hypoglottidei DC. and 11 species from Dissitiflori DC. section were used in the current study. The total length of the ITS region was 642 bp with 56 (8.7 %) parsimony-informative and 9 insertion\...
A new species of Acantholimon Boiss. sect. Glumaria Boiss. (Plumbaginaceae) from Elazig, Turkey Dogan, M; Akaydin, G (Oxford University Press (OUP), 2005-11-01) A new species, Acantholimon evrenii sp. nov. is described and illustrated for the first time in sect. Glumaria from Turkey. The species is confined to B7 Elazig in East Anatolia where it grows on rocky mountain steppes. The diagnostic morphological characters from closely related species are given, along with a discussion dealing with its taxonomic relationship. Its conservation status is indicated. A revised key is also provided for the Acantholimon species with heterophyllous leaves, two or more flowered ...
A new species, Acantholimon birandii (Plumbaginaceae), from the Central Anatolian Steppe in Turkey Doğan, Musa (Wiley, 2001-01-01) A new species, Acantholimon birandii, is described and illustrated from Karaman, Turkey.
Morphology, anatomy, palynology and nutlet micromorphology of the rediscovered Turkish endemic Salvia ballsiana (Lamiaceae) and their taxonomic implications Kahraman, Ahmet; Doğan, Musa; Celep, Ferhat; AKAYDIN, GALİP; KOYUNCU, MEHMET (Wiley, 2010-01-01) Salvia ballsiana (Rech. fil.) Hedge, previously known only from the type gathering, is a local endemic species from Turkey. The species was first collected from Golbasi (Malatya) by E. K. Balls in 1935, and was not collected again until 2008, when we found it in Gerger (Adiyaman). The diagnostic morphological characters of this rare endemic species are discussed, including its anatomical, palynological and nutlet micromorphological features. Morphological characteristics of leaves, calyces, corollas and typ...
Pollen morphology of some taxa of Vicia L. subgenus Vicia (Fabaceae) from Turkey KAHRAMAN, AHMET; Binzat, Okan Kaan; Doğan, Musa (Springer Science and Business Media LLC, 2013-11-01) In this study, the pollen morphology of 11 taxa belonging to Atossa (Alef.) Asch. & Graebner, Hypechusa (Alef.) Asch. & Graebner, Peregrinae Kupicha, Wiggersia (Alef.) Maxted, Vicia L. and Narbonensis (Radzhi) Maxted sections of the genus Vicia L. subgenus Vicia (Fabeae, Fabaceae) naturally growing in Turkey has been studied using Light Microscopy (LM) and Scanning Electron Microscopy (SEM) to evaluate the taxonomic relevance of pollen characters. Twelve morphometric characters are analysed with one-way ana...
