In this study, description and illustration, diagnostic morphological characters, habitat, distribution, ecological characteristics, conservation status, seed micromorphological characters (LM and SEM) and comparisons with close species are given.Öğe The last missing species born of a confusing puzzle: Leopoldia nigdeensis (Asparagaceae, Scilloideae), a new species from Türkiye(Magnolia Press, 2024) Eker, Ismail; Eroglu, HuseyinThe concept of Muscari massayanum (=Leopoldia massayana), previously treated by Davis & Stuart in the Flora of Turkey, was found to be a mixed species assemblage and included the species Muscari erdalii (=Leopoldia erdalii) and Muscari erzincanicum (=Leopoldia erzincanica), which arose from this confusion. However, in the latest evaluations by the authors of this article, the last missing piece of the confusing puzzle has been put forward in this study. Thus, a new species Leopoldia nigdeensis from Anatolia is described in this study. The new species is morphologically partly similar to Leopoldia massayana, L. erzincanica, L. oztasii, L. tenuiflora and L. erdalii, but differs from all of them with clear features in flower, fruit and seed characteristics.Öğe The morphological and anatomical properties of endemic Crocus leichtinu (D. Dewar) bowles (Iridaceae) in Turkey(Pakistan Botanical Soc, 2007) Akan, Hasan; Eker, Ismail; Satil, FatihIn this investigation, some morphological and anatomical characteristics of Crocus leichtlinii (D.Delwar) Bowles, an endemic species which has flowering time in early spring, were observed. The specimen was collected from Sanliurfa, South East Anatolia, within C7 of the grid system; its habitat and population status was also determined. Morphological features of species such as leaf, bracteol, flower, and fruit have been described in detail. The determination of the anatomical characteristics present the first data available in the literature. In anatomical studies, transverse sections of leaf and root have been examined and supported by illustration. Anatomical characters of species were observed to have been similar to usual features of Iridaceae anatomy.Öğe The morphological and anatomical properties of endemic Crocus leichtlinii (D.

It has no closely related species, and is partly similar to M. pseudopallens and M. pallens, but differs from them mainly in morphological characters such as outer tunic color, raceme shape and density, pedicels no extending when in fruit, shape of fertile flowers with shouldered and grooved, color when dry, color of lobes, strongly compressed capsule valves, as well as flowering time and habitat characteristics. In this study, a comprehensive description, diagnostic characters, original photographs, geographical distribution, conservation assessment, and taxonomic comments on the new species are presented.Öğe A new Leopoldia (Asparagaceae, Scilloideae) species from South Anatolia-Türkiye: Leopoldia oztasii(Magnolia Press, 2024) Eroglu, Huseyin; Pinar, Suleyman Mesut; Eker, IsmailLeopoldia oztasii sp. nov. (Asparagaceae, Scilloideae) is described as a new species in this study. It spreads on the stony slopes of Konya province in the south of Turkiye. Leopoldia oztasii is similar to L. tenuiflora, but it is easily distinguished from it, by having larger bulbs, falcate leaves, shorter scape, conical inflorescence, longer pedicels, and larger capsules. In this study, the morphology, seed surface characteristics and ecology of L. oztasii were studied. A detailed description of the new species, a comparison table between the two species, and detailed photographs showing their differences are provided. The distribution areas of L. oztasii and L. tenuiflora in Turkiye are also presented on the map.Öğe Phylogeny and infrageneric classification of tulips(Springer Wien, 2024) Eker, Ismail; Hacioglu, Burcu Tarikahya; Ozgisi, KurtulusDespite many studies conducted over a period of nearly two centuries since Reboul, who was the first to classify tulips as subgeneric level, there is still no consensus among researchers regarding the infrageneric classification of tulips. Nevertheless, in recent years, efforts to solve this taxonomic problem have been increasing. However, phylogenetic studies covering all species of a genus or at least with species representatives of all subgeneric taxonomy worldwide are very scarce. The main difference of the current study from previous studies is that it is a larger study focused on solving this problem by considering all perspectives together, covering many geographical areas and species in global distribution. For this purpose, we examined the phylogenetic relationships of the genus Tulipa with 82 accessions from 45 Tulipa species and six accessions from two Amana and three Erythronium species, and we positioned our results by discussing them in light of previous morphological, geographical, molecular and anatomical data. We investigated the phylogenetic relationships in the genus using DNA sequences from the internal transcribed spacer region of nuclear ribosomal DNA. The 45 species of Tulipa formed a monophyletic clade. Genera Amana and Erythronium were clustered as outgroups. In the genus Tulipa, two major clades were obtained; the first clade belonged to subgenus Orithyia. The second clade separated subgenus Tulipa and subgenera Eriostemones+Clusianae. Then, Eriostemones and Clusianae subgenera formed two separate clusters. Subgenus Eriostemones separated two main clusters; section Biflores and section Sylvestres. On the other hand, all previously proposed sections and series under the subgenus Tulipa were grouped into a single clade. This situation agrees with previous biosystematic data highlighting the morphological overlap of most of the sections and with previous molecular data showing that many sections are not monophyletic. Consequently, we propose a taxonomic concept consisting of four subgenera and two sections.Öğe Türkiy'nin endemik digitalis (Scrophulariaaceae) türlerinin in vitro çoğaltımı ve kalp glikozitlerinin üretilmesi(2010) Gürel, Ekrem; Eker, Ismail; Sökmen, Münevver; Sökmen, Atalay; Yücesan, Bahtiyar Buhara-Öğe Türkiye Florası İçin Doğallaşmış Yeni Bir Egzotik Bitki Kaydı: Freesia leichtlinii subsp. alba (Iridaceae)(2021) Eker, Ismail; Tuzlaci, Halil IbrahimGüney Afrika’da Cape Bölgesi’nde doğal yayılış gösteren Freesia leichtlinii subsp. alba(Iridaceae) Türkiye Florası için doğallaşmış egzotik bir takson olarak ilk kez kaydedilmektedir.İstanbul'un Adalar bölgesinde (Kınalıada, Heybeliada ve Burgazada) tespit edilen taksona aitpopülasyonlar sonraki üç yıl boyunca izlenerek taksonun doğallaşıp doğallaşmadığı, insanetkisi olmaksızın vejetatif ve generatif üremeye devam edip etmediği ve sürekli bir popülasyonoluşturup oluşturmadığı takip edildi. Daha sonra, Türkiye'nin egzotik flora listesi ile dünyayabancı bitki listeleri kontrol edilerek taksonun Türkiye için ilk defa kaydedildiği sonucunavarıldı.

Ancak buradakiçalışmada ilk yazarın ISTE herbaryumunda 2016 ve 2019 yıllarında incelediği örneklerarasında M. kerkis kaydının kanıt örneklerine ulaşılamamıştır. Bunun üzerine yeni kaydınverildiği orijinal yayında gösterilen adreslerde yaptığımız detaylı saha çalışmalarında, dahaönce toplanan örneklerin aslında M. neglectum Guss. ex Ten. olduğu anlaşılmıştır. AydınDağları’ndan 2019 ve 2020 yıllarında topladığımız örneklerin ise tip örneğiyle dekarşılaştırılmasıyla, özgün M. kerkis’i temsil ettiği sonucu ortaya konulmuştur. Dolayısıyla, buçalışma ile M. kerkis Aydın Dağları’ndan toplanan örneklere göre Türkiye’den ilk kezkaydedilmiştir. Yeni kayıt taksonun yakın akraba olduğu Botryanthus altcinsi içerisinde yeralan M. neglectum ve M. pulchellum Heldr. & Sart. ex Boiss. subsp. pulchellum ile olantaksonomik ilişkileri karşılaştırılmış ve yeni kaydın genişletilmiş bir betimi ve habitatözellikleri verilmiştir.
