    A new species of Gladiolus from Southeastern Turkiye, Gladiolus siirtensis (Iridaceae, Crocoideae)
    (Magnolia Press, 2023) Pinar, Suleyman Mesut; Eroglu, Huseyin; Fidan, Mehmet
    Gladiolus siirtensis (Iridaceae) is described as a new species from the Pervari district, Siirt province in the southeast of Turkiye. Gladiolus siirtensis is similar to G. humilis, but it is easily distinguished by its shorter stem, oblong or oblanceolate first leaves, dense spike with secund flower arrangement, absence of fusiform blotch on the lower segments of perigone, shorter anthers, style and stigma lobes and obovoid capsule. A detailed morphological study, including pollen and seed surface characteristics was undertaken for the new species. A complete morphological and palynological description is provided, including distribution data of the new species and related ones.

    Bellevalia behcetii sp nov (Asparagaceae): a new species from South Eastern Anatolia, Turkey
    (Magnolia Press, 2016) Pinar, Suleyman Mesut; Eroglu, Huseyin; Fidan, Mehmet
    Bellevalia behcetii (Asparagaceae) is described and illustrated as a new species from Sirnak province in South Eastern Anatolia (Turkey). It is morphologically similar to B. paradoxa but easily differs in several morphological characters. Diagnostic morphological characters, a full description and detailed illustrations of the new species are provided. A quantitative morphometric analysis was carried out to check the diagnostic characters of Bellevalia behcetii with respect to morphologically related species. The somatic chromosome number was determined as 2n = 2x = 8 in B. behcetii. In addition, the ecology and phenology of the new species, as well as its etymology and the pollen characteristics, are presented and discussed. The conservation status of B. behcetii was assessed according to IUCN protocol. A distribution map of B. behcetii and related species is also presented.

    Karyotype analysis of five endemic Bellevalia species from Turkey
    (Univ Tokyo Cytologia, 2024) Dogan, Gulden; Kiran, Yasar; Eroglu, Huseyin; Fidan, Mehmet; Pinar, Sueleyman Mesut
    This study aimed to investigate the somatic chromosome numbers and morphometric properties of chromosomes in five endemic species of the genus Bellevalia Lapeyr. (Asparagaceae) from Turkey. The examined taxa are B. behcetii Pinar, Ero & gbreve;lu & Fidan, B. koyuncui Karabacak & Yildirim, B. pseudolongipes Karabacak & Yildirim, B. sasonii Fidan, and B. vuralii B.& Scedil;ahin & Aslan. Karyological techniques were employed to assess the chromosome number and morphology of the species. The genus Bellevalia is by a basic chromosome number x = 4. Chromosome numbers of the species were determined B. behcetii , B. koyuncui , B. pseudolongipes , and B. sasonii 2 n =2 x = 8, while B. vuralii 2 n =4 x = 16, was determined. Satellites were observed in two species; B. behcetii and B. vuralii . Using the Stebbins classification system, species were categorized as class 3A. Additionally, various parameters such as chromosome number, total chromosome length, relative length, arm ratio, centromere index, and centromere states, karyotype asymmetry values, and karyotype formula were determined. Notably, this study marks the first time that chromosome numbers of B. sasonii have been defined, contributing valuable new data to the systematics of these species.

    Muscari sabihapinari sp. nov. (Asparagaceae) from Anatolia, Turkey
    (Wiley, 2019) Eroglu, Huseyin; Pinar, Sueleyman Mesut; Fidan, Mehmet
    We describe Muscari sabihapinari (Asparagaceae: Scilloideae) as a new species from the Adana and Sivas provinces in South Anatolia, Turkey. It grows in rocky-stony steppe habitats. Muscari sabihapinari shows general aspect similar to that of M. anatolicum, M. atillae and M. discolor but is easily distinguished from them by its bulb, leaf and flower characteristics. A complete morphological description, identification key, pollen characteristics, detailed photographs, comparative photographs and comparison table with the closely related species are presented.

    Seed micromorphology and anatomy of 36 Muscari (Asparagaceae) taxa from Turkey with notes on their systematic importance
    (Univ Zagreb, Fac Science, Div Biology, 2021) Eroglu, Huseyin; Karaismailoglu, Mehmet Cengiz; Pinar, Suleyman Mesut; Fidan, Mehmet
    - This study presents the first in-depth evaluation of the morphological and anatomical characters, as well as their taxonomic importance, of the seeds of 36 taxa in subgenera Muscari, Leopoldia, Pseudomuscari and Botryanthus of the genus Muscari in Turkey, where 24 of the taxa are endemic. The results indicate that the taxa generally differ from each other in terms of seed shape and dimension. Seed dimensions vary between 1.66 mm and 3.21 mm in length, and between 1.12 mm and 2.63 mm in width. The seed surface ornamentation is grouped into nine forms: ru- minate, reticulate, reticulate-areolate, reticulate-foveate, alveolate, scalariform, rugose, verrucate and areolate. The most common type is ruminate, while areolate, reticulate-foveate and scalariform ornamentation forms were found to be taxon-specific. Testa structures of the taxa examined consist in general of two different layers: the epidermis and the subepidermis in scleranchymatous or parenchymatous structures. The subepidermis may be absent in some of taxa. The structure and thickness of the epidermis and the subepidermis are very important characteristics that dis- close interspecific relations among the examined taxa. We also provide a key for the identification of the studied taxa based on seed features.

    Seed Morphological and Anatomical Structures as Taxonomy Tool for Turkish Hyacinthella Schur (Asparagaceae) Taxa
    (Magnolia Press, 2022) Eroglu, Huseyin; Karaismailoglu, Mehmet Cengiz; Fidan, Mehmet; Pinar, Suleyman Mesut
    This paper offers the first taxonomic assessment of the morphological and anatomical characters of the seeds of 11 Hyacinthella taxa from Turkey, ten of them are endemic, with the cluster analysis and principal component analysis. Macro-morphologically, all studied species can be differentiated from each other by the seed characters such as shape, size and surface ornamentation. The studied seeds are separated into 5 shapes; triangularis, circularis, ellipticus, ellipticus-late and ovatus. Seed size ranges from 1.51 mm to 3.06 mm in length and from 1.06 mm to 2.04 mm in width. Micro -morphologically, seed surface ornamentation is grouped into 7 types: rugose, reticulate-pusticulate, verrucate, tuberculate, ruminate, reticulate-foveate and alveolate. Anatomically, testa structures of the studied seeds are usually consisted of single layer, the epidermis, formed in the sclerenchymatous tissue. The epidermis layer demonstrates significant differences in cell form, comprising of crushed, flat or polygonal cells, in 1-7 layers, and has surged or straight wall form. The thickness of testa layers varies between 15.77 mu m (in H. micrantha) and 49.76 mu m (in H. campanulata). In the systematics of the genus Hyacinthella, the seed morphological and anatomical characters are very important characteristics that reveal inter-specific relationships among the studied species. Also, a dichotomous key is provided for the identification of the examined species based on seed characters.
