    Haplophyllum sahinii (Rutaceae), a new species from Central Anatolia (Turkey)
    (MAGNOLIA PRESS, 2017) Tugay, Osman; Ulukus, Deniz
    Haplophyllum sahinii (Rutaceae) is described and illustrated as a new species, growing in the rocky fields near the village of Apasaraycik-Apa (Konya), in Central Anatolia. It is compared with the similar H. vulcanicum from Karadag (Karaman) in south-central Turkey, from the point of view of plant, pollen and seed morphology. Some morphological characters of leaves, bracts, petals, ovary and capsule appendage are diagnostic in distinguishing the two species. Distribution map, and description of seed and pollen characters of the new species, are also given.

    Linum aksehirense (sect. Dasylinum, Linaceae), a new species from Central Anatolia (Turkey)
    (PENSOFT PUBLISHERS, 2019) Tugay, Osman; Ulukus, Deniz
    Linum aksehirense (Linaceae) is described as a new species known from the slopes of the Sultan Mountains in the Aksehir district of Konya in Central Anatolia (Turkey). It is most similar to L. pubescens Banks & Sol. and L. anisocalyx P.H.Davis, from which it is easily distinguished by its stem leaf shape, sepal shape and petal colour. Seed and pollen surface ornamentations were photographed under SEM microscopy to explore micromorphological characters distinguishing the new species from close relatives. In addition, photographs of living material, a distribution map, ecological details, and an identification key are provided.

    Morphology, Anatomy and Palynology of Turkish endemic species Haplophyllum myrtifolium, H. vulcanicum & H. megalanthum (Rutaceae) and their systematics implications
    (MAGNOLIA PRESS, 2016) Ulukus, Deniz; Tugay, Osman; Celep, Ferhat
    Haplophyllum is one of the taxonomically difficult genera in the Rutaceae. Three Turkish endemic species of Haplophyllum, namely Haplophyllum myrtifolium, H. vulcanicum and H. megalanthum, have similar morphological features, therefore identification of the species are extremely difficult. In the present study, morphological, anatomical and palynological characteristics of the species are examined in order to understand the usefulness of these characteristics for systematics purposes. Morphological characteristics of leaves and corollas, absence/or presence of glandular hairs on the stem and inflorescence, expansion form of filaments and ovarium appendage are useful for specific delimitation among the species. Anatomical characters such as number of cortex layers and sclerenchymatic cell layers in stem, size of the vascular bundle in the midrib provide information of taxonomical significance. In addition, exine sculpturing pattern of pollen grains can be used for taxonomic purposes.

    Morphology, anatomy and palynology study on Turkish endemic species Saponaria karapinarensis (Caryophyllaceae)
    (MAGNOLIA PRESS, 2018) Ulukus, Deniz
    Saponaria karapinarensis (Caryophyllaceae), an endemic species from Turkey, was studied from taxonomic point of view. Morphological, anatomical, and palynological characteristics of the species were examined. Morphology of stem, calyx, petals, and capsule are useful to distinguish the species. Anatomical features, such as the umber of cortex layers and sclerenchymatic cell layers in stem, are of taxonomical importance. SEM Scanning Electron Microscopy (SEM) studies on the pollen grains have revealed that they are spheroideae and their exine ornamentation is granulatae, spinulate microechinatae-microperforatae. Seed micromorphological features were also given.

    A new species of Cousinia (sect. Cousinia, Asteraceae) from the Agri Mountain (eastern Turkey): evidence from morphology, karyology and anatomy
    (MAGNOLIA PRESS, 2019) Tugay, Osman; Ulukus, Deniz; Ertugrul, Kuddisi; Uysal, Tuna; Demirelma, Hakki; Dural, Huseyin
    Cousinia agridaghensis (sect. Cousinia) from Agri province, eastern Turkey, is described as new to science. The new species is morphologically closely related to C. urumiensis, C. fedorovii and C. armena but differs in capitula shape, synflorescence shape, stem height, shape of segments of basal and uppermost cauline leaves. In addition, the new species is compared with C. urumiensis, which is distributed in Turkey, in terms of chromosome number and anatomical features. The basic chromosome number is determined x = 12 in C. agridaghensis and x = 13 in C. urumiensis. The differences in leaf midrib shape and number of vascular bundles in C. agridaghensis and C. urumiensis are observed. The achene coat and pollen grain surface of C. agridaghensis and C. urumiensis are studied with SEM photographs. Furthermore, a detailed description, distribution map, conservation status and ecology of the new species are given.
