  Seed morphology of some Eremogone species (Caryophyllaceae) from Türkiye

  Tokuşoğlu, Kader Varlik; Armağan, Metin; Bülbül, Ali Savaş

  The present research deals with the taxonoy of the genus Eremogone, using morphology of seed; the species occurring in Türkiye are examined. Nineteen characters (qualitative and quantitative) were observed or measured using light microscopy and Scanning Electron Microscopy; statistical analyses considered are PCA and Clustering. The average length of Eremogone seeds was 1756 μm (1168–2569 μm), and the average width was 1148 μm (866–1674 μm). Seed shape, based on the seed length-to-width ratio, ranged from spherical to prolate spheroidal. Seed colors varied from yellowish-brown to dark brown-black. The seed coat surface was covered with tubercles, and the dorsal surface of the seed was covered with papillae ranging from 27 to 146 in length. The identified potential characters contribute to the delimitation of the Turkish species of Ermogone; a diangostic key is proposed.

  Pollen morphology of Eremogone (Caryophyllaceae) in Türkiye

  Tokuşoğlu, Kader Varlik; Armağan, Meti̇N; Bülbül, Ali̇ Savaş

  The palynological characters of 17 taxa belonging to genus Eremogone Fenzl (Caryophyllaceae) from Türkiye were examined using light microscopy and scanning electron microscopy. Eremogone pollen in Türkiye is found to have an average size of 31.31 μm (26.62‒36.65 μm), pore sizes ranging from 6.52 to 9.24 μm, inter-pore distances ranging from 9.07 to 12.57 μm, pore numbers varying from 5 to 14 and 5‒30 nanoechini distributed in an area of 10 × 10 µm. The ornamentation was identified as nanoperforate, nanoechinate, or nanofaveolate surface elements in various combinations. Clustering analysis and Principal Component Analyses do not show clear groups, although more similar taxa were brought together through the analysis of pollen micromorphological data rather, the nanoechinate base width, nanoechinate length, and pore diameter length are the most valuable variables for separating the examined taxa.

  Androsace artvinensis sp. nov. (Primulaceae): A new species from northeastern Anatolia, Turkey

  Sefali, Abdurrahman; Yapar, Yakup

  Androsace artvinensis (Primulaceae) from Artvin province (northeastern Anatolia) has been described as a new species to science. The new species is morphologically similar to A. armeniaca var. macrantha but differs from it by several morphological characters, such as bracts shape, calyx (calyx length and lobes), corolla (corolla length, lobes, and indumentum), hairs, leaves, pollen features, and habitat preference. Diagnostic morphological characteristics, a full description, and a distribution map are provided.

  Pastinaca vanensis (Apiaceae), a new species from Turkey

  Demir, Ibrahim; Sefali, Abdurrahman; Yapar, Yakup

  Pastinaca vanensis is described as a new species from the Başkale district (Van-Turkey). Its diagnostic characteristics are discussed, and taxonomic comments are presented. P. vanensis is related to Pastinaca zozimoides but differs from this species in indumentum, petal color, and mericarp features. Data on ecology and the conservation status of the new species are also presented. A distribution map of the new and related species is provided.

  Pollen morphology of some Veronica species (Plantaginaceae) from Turkey

  Varlik, Kader; Armagan, Metin; Bülbül, Ali Savaş

  The aim of the present work is to provide an account on the morphological features of pollen of Veronica species in Turkey, as a contribution to future research. Pollen morphology of 20 species of the Veronica were investigated using Light Microscope (LM) and Scanning Electron Microscope (SEM). Different palyno-morphological features including; pollen ornamentation, colpus ornamentation, size of polar and equatorial diameter, P/E ratio, exine thickness, and size of colpus were observed. The study revealed that the pollen grains of the studied Veronica species were in all cases tricolpate, radially symmetrical and isopolar, oblate-spheroidal or prolate spheroidal. The surface pattern of the exine varied from striato-reticulate and striatomicroreticulate to microechinate-perforate, which allows recognition of three homonymous types of pollen grains.

  Bellevalia bayburtensis (Asparagaceae): a new species from northeastern Anatolia, Turkey

  Yildirim, Hasan; Sefali, Abdurrahman

  Bellevalia bayburtensis (Asparagaceae) is described and illustrated as a new species from Bayburt Province in northeastern Anatolia, Turkey. Diagnostic morphological characters, a full description, detailed illustrations, and a distribution map are provided. It is morphologically similar to B. rixii and B. paradoxa, but clearly differs from these species by the leaf shape, the bud and flower colour.
