    A new Gladiolus (Iridaceae) species from East Anatolia (Turkey): Gladiolus hamzaoglui
    (Magnolia Press, 2021) Tekşen, Mehtap; Duman, Hayri; Sağıroğlu, Mehmet
    Gladiolus hamzaoglui (Iridaceae) is described and illustrated as a new species from Erzincan province in Eastern Anatolia, Turkey. It resembles G. halophilus by its secund inflorescence, obovoid fruit, and winged seed, and is related to G. anatolicus based on its leaf and flower features. Also it is compared to G. illyricus because of having some leaf, flower features, and winged seed characteristics. Its distribution, habitat and ecology, etymology, conservation status and diagnostic morphological, and taxonomic features with familiar species are discussed in this paper. Additionally, pollen and seed micromorphological characteristics of G. hamzaoglui, G. halophilus, and G. anatolicus are examined and compared using LM and SEM analyses IUCN conservation status of G. hamzaoglui is suggested as Endangered (EN) category.

    Astragalus oksutdagensis (Fabaceae), a new species from Turkey
    (John Wiley and Sons Inc, 2022) Karaman Erkul, Seher; Duman, Hayri; Ateş, Mevlüde Alev
    This study describes the new species Astragalus oksutdagensis (A. sect. Eustales) from Kayseri, Turkey. The species is compared morphologically to the two similar species A. flavescens and A. vestitus, considering also pollen micromorphology. The geographical distribution of A. oksutdagensis, A. vestitus and A. flavescens is mapped. The phylogenetic relationships between the new species and other closely related species in the genus are inferred based on DNA data from the internal transcribed spacer regions (ITS) and it is shown that A. sect. Eustales is monophyletic but closely related to A. sect. Tragacantha. The new species is assessed as critically endangered (CR) following the IUCN Red List Categories and Criteria.

    Gladiolus alanyensis (Iridaceae), a new species from southern Turkey in the eastern Mediterranean basin
    (Magnolia Press, 2022) Sağıroğlu, Mehmet; Tekşen, Mehtap; Duman, Hayri; Karaman, Seher; Çakır, Ece Gökçe
    Gladiolus alanyensis is described and illustrated as a new species from Alanya, Antalya Province in South Anatolia, Turkey. In this study, the diagnostic morphological features, distribution, habitat and ecological characteristics, and conservation status of the new species are reported. It grows in calcareous areas and is morphologically close to G. anatolicus. Affinities and differences to other species such as G. triphyllus and G. humilis are also commented. Seed micromorphological characteristics of G. alanyensis, G. anatolicus and G. humilis are examined and compared using LM and SEM analyses.

    Ranunculus aydogdui (Ranunculaceae), a new species from Turkey
    (Wiley, 2021) Erkul, Seher Karaman; Tekşen, Mehtap; Duman, Hayri
    Ranunculus aydogdui sp. nov. is described from Tuz Golu (Salt Lake), Aksaray, Turkey. It is compared to three similar species, R. flammula, R. pulchellus var. pulchellus and R. indivisus and it is found that R. aydogdui is distinguished from them e.g. by having tuber roots. A comprehensive description, ecology, distribution map, detailed photographs, pollen morphology and comparison of the new species with closely related species are provided. The new species is assessed as Critically Endangered (CR) following IUCN Red List Categories and Criteria.

    Tripleurospermum eskilensis (Asteraceae): a new halophytic species from Central Anatolia, Turkey
    (Türkiye Klinikleri, 2022) Tekşen, Mehtap; Karaman Erkul, Seher; Duman, Hayri; Ateş, Mevlüde Alev; Sağıroğlu, Mehmet
    In the present study, a new species of the genus, Tripleurospermum eskilensis (Asteraceae), is described from Central Anatolia, Turkey. The new species has been collected from Eskil region in a restricted area (Aksaray Province). It grows in salty steppe, and is closely related to T. decipiens in terms of morphological characteristics. It has also been morphologically compared with discoid and disciform capitulated species in Turkey. This study includes its detailed description, diagnostic characters, original photographs, geographical distribution, habitat and ecology, conservation status, and identification key. The comparison of Tripleurospermum eskilensis with closely related species was conducted in terms of morphological characteristics, pollen, achene morphology and anatomy, stomatal length, and molecular phylogenetic analysis.
