Alkanna malatyana (Boraginaceae), a new species from East Anatolia, Turkey

WOS: 000333898000006Alkanna malatyana (Boraginaceae) is described as a new species to science. It is endemic to the eastern Anatolia region of Turkey. A. malatyana is an obligated chasmophytic species, which colonizes on limestone rocky cliffs, known from a single locality in Levent Canyon, located in Malatya Province. It is related to A. mughlae and it shows some morphological similarities with A. confusa and A. kotschyana, but it clearly differs from them based on the morphological differences presented in the species description. In addition, the conservation status, a distribution map, and notes on the biogeography and ecology of the new species are given.Ege University Research FundEge University [2012 BBH 001]We are grateful to the curators of the following herbaria for allowing access to their Alkanna material for study: ANK, EGE, GAZI, HUB, KONY, K, and VANF.

Reseda malatyana (Resedaceae), a new chasmophytic species from eastern Anatolia, Turkey

WOS: 000342607700013Reseda malatyana Ysidirim & Senol (Resedaceae) is illustrated and described as a new species to science, endemic to eastern Anatolia, Turkey. Reseda malatyana is related to Reseda armena Boiss. It differs from Reseda armena by the following characters: densely smaller, unbranched at the upper part, papillate-hispidulous stems; dark green, thicker, and densely papillate-hispidulous leaves; bigger petals; smaller pedicels; relatively smaller with sinus seeds; oblate-spheroidal, tricolporate, and rugulate pollen grains. R. malatyana is a perennial species that colonizes on marlstone rocky cliffs, known from a single locality in Levent Canyon, located in Malatya Province. It is an obligated chasmophytic species. In addition, the conservation status, distribution map, and notes on the biogeography and ecology of the new species are given. Moreover, the morphological description of Reseda armena, a poorly known and insufficiently characterized species due to its rarity and very limited material present in herbaria, is amplified and expanded based on the present material obtained from field studies and several herbaria

Farklı habitatlarda Convolvulus oleifolius var. Deserti'nin morfoloji ve fizyolojisinde değişimler

Apostol adasının farklı vejetasyon zonlarında bulunan Convolvulus oleifolius Desr. var. deserti Pamp./Sürmeli yayılgan'ın morfolojik özellikleri, fotosentetik pigment içerikleri, prolin ve toplam protein miktarları çalışılmıştır. Örnekler Bodrum-Türkbükü-Muğla-Türkiye, Apostol adasının littoral-epilittoral ve interior vejetasyon zonlarından toplanmıştır. Gövde uzunluğu, organ büyüklüğü, tüy yoğunluğu ve çiçeklenme durumunda belirgin farklılıklar vardır. Fotosentetik pigmentler littoral-epilittoral vejetasyon zonda, interior vejetasyon zondakinden daha azdır. Littoralepilittoral vejetasyon zonda prolin miktarı interior vejetasyon zondakinden önemli derecede daha yüksekken, toplam protein miktarı önemli derecede daha düşüktür. C. oleifolius var. deserti'nin morfolojik ve fizyolojik özelliklerinin çeşitli habitatlara uyum mekanizması sonucu ortaya çıkan önemli farklılıkları sergilediği düşünülebilir. Bu nedenle, çalışmamız farklı habitatlara uyumlu ve/veya toleranslı bitkilerin seçilmesi ve değerlendirilmesi için önemlidirMorphological features, photosynthetic pigment contents, proline and total protein amounts of Convolvulus oleifolius Desr. var. deserti Pamp./Surmeli yayilgan in different vegetation zones of Apostol Island are studied. Samples were collected from littoral-epilittoral and interior vegetation zones of Apostol Island, Bodrum-Turkbuku-MuglaTurkey. There are obvious differences in terms of stem length, organ size, hair density and inflorescence. Photosynthetic pigments in littoral-epilittoral vegetation zone are less than in interior vegetation zone. Prolin amount is significantly higher, but total protein amount is significantly lower in littoral-epilittoral vegetation zone than in interior vegetation zone. It may be thought that the morphological and physiological features of the C. oleifolius var. deserti exhibited considerable differences which appeared be the product of adaptive mechanisms to different habitat. So, our study is important for improving and selecting crops tolerant of and/or adapted to different habita

Heterostyly in Linum aretioides

WOS: 000321228000012The petal width; sepal, pistil, and stamen lengths; and changes in pollen sizes associated with heterostyly of different morphs in populations of Linum aretioides Boiss. were investigated. Fruit sets were compared in 2 populations and it was investigated whether the Bozdag population has a heteromorphic incompatibility system. It was observed that the stamen lengths of thrum morphs of Bozdag were shorter than those of thrum morphs of Babadag. Pistil lengths of both morphs of Bozdag were longer than those of morphs of Babadag. Pollen shapes of both morphs were prolate-spheroidal and subprolate, respectively, in the Bozdag population and subprolate in the Babadag population. It was determined that pollen exine in the short-styled and long-styled flowers was dimorphic. The pollen bore a marginal ring of 4 to 8 spinules in the thrum morphs and of 3 to 7 spinules in the pin morphs. It was found that the highest rates of fruit set occurred during cross-hand pollination from pin morphs to thrum morphs and from thrum morphs to pin morphs (77.77% and 71.42%, respectively). It was shown that in L. aretioides self-pollinations and pollinations between plants of the same morph are incompatible.TUBITAKTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [104T340]We would like to extend our thanks to TUBITAK (Project no: 104T340) for its financial support

Ekimia ozcan-secmenii (Apiaceae), a new species from Southwest Anatolia, Turkey

WOS: 000439576800012Ekimia ozcan-secmenii Senol & Eroglu sp. nov. (Apiaceae) is described from SW Turkey. E. ozcan-secmenii differs from its close affinity, E. bornmuelleri, by life form (monocarpic), petal and bracteole morphology, and mericarp features. These data were more supported by the results of nrDNA ITS sequences. The ML tree depicted based on phylogenetic studies aimed to reveal the closeness of the Laserpitium and Prangos species as well as the location the affinity of species in the genus Ekimia. The taxonomic situation of Prangos hulusi was also evaluated based on nrDNA ITS sequences. Since E. ozcan-secmenii is distributed in Sami Soydam Sandalcik hydroelectric power plant in Acipayam, Denizli, the population is threatening by flooding. Therefore, conservation programs are urgently recommended.TUBITAKTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [TBAG-108T851]The author would like to thank the curators of GAZI and EGE Herbaria for their helpful assistance.

Helichrysum x kani-isikii (Asteraceae), a new nothospecies from Turkey

In this study, Helichrysum x kani-isikii (Asteraceae), a new natural hybrid of H. compactum and H. unicapitatum from Babadag (Denizli, Turkey), is described and investigated in detail for the first time. The new nothospecies is similar to H. compactum and H. unicapitatum, but it has some intermediate morphological and palynological properties that position it between the two putative parents. In the diagnosis of the hybrid, pollen size and shape were found as significant characteristics. Taxonomic, morphological, and palynological characteristics of H. x kani-isikii are compared with those of its putative parents, and some other details are presented with notes on the IUCN category and ecology of the nothospecies. In addition, a key to diagnosing the hybrid from its parental taxa is also provided.This research was financially supported by the Pamukkale University Scientific Research Coordination Unit (under project no: 2019KRM004) .
