    Comparative anatomical and micromorphological studies on Teucrium creticum and Teucrium orientale var. orientale (T. sect. Teucrium, Lamiaceae)
    (WILEY-BLACKWELL PUBLISHING, INC, 2009) Dinc, Muhittin; Dogu, Sueleyman; Bilgili, Bilgehan; Duran, Ahmet
    Teucrium creticum L. and T. orientale L. var. orientale are two related taxa in Teucrium sect. Teucrium. In this study, the value of anatomical and micromorphological characters for distinguishing between these two taxa is analysed. Transverse sections of the stem, as well as both transverse and surface sections of the leaves were examined anatomically. According to the data obtained, collenchyma and sclerenchyma do grow more in T. creticum than in T. orientale var. orientale. The leaves of T. creticum are hypostomatic and have a characteristic hypodermis, which is under the upper epidermis, as well as abundant spherocrystals in the upper epidermis. The leaves of T. orientale var. orientale are amphistomatic, yet no spherocristals exists in epidermal cells and the hypodermis is absent. The results obtained from studies carried out under scanning electron microscope (SEM) shows that the nutlet micromorphology varies between the two taxa. In both taxa, the nutlet surfaces are reticulate and glandular. Eglandular hairs do occur. However, in T. orientale var. orientale, 20-60 mu m long eglandular hairs with scabrid surface occur only along the margins of the nutlets, whereas the 3/4 dorsal sides of the nutlets in T. creticum are all covered with 90-500 mu m long, smooth-surfaced hairs. Additionally, while the glandular hairs on the nutlets of T. creticum are subsessile, those on the nutlets of T. orientale var. orientale are capitate and distinctly stalked.

    Dichoropetalum alanyensis (Apiaceae), a new species from South Anatolia, Turkey
    (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2016) Bilgili, Bilgehan; Sagiroglu, Mehmet; Seker, Meryem; Duman, Hayri
    Dichoropetalum alanyensis Bilgili, Sagiroglu & H. Duman, a new species from South Anatolia in Turkey (Antalya-Alanya), is described and illustrated. It is closely related to D. chryseum (Boiss. & Heldr. ex Boiss.) Pimenov & Kljuykov, from which it differs mainly by its habit, basal leaves and lobes, and mericarp features. Diagnostic morphological characters are discussed. Notes are also given on its ecology and conservation status, together with scanning electron micrographs of mericarp surface sculpturing pattern. ITS sequences were used for DNA fingerprinting. The data were analyzed with the SEAVIEW package. Standardized data were used to generate a dendrogram that revealed the phylogenetic relationships of taxa in tribes Selineae (Dichoropetalum-Johrenia), Tordylieae (Cymbocarpum), and Bupleureae (Diplotaenia) from different localities.

    A new subspecies of Centaurea cassia (Asteraceae) from Turkey
    (VERSITA, 2009) Dinc, Muhittin; Duran, Ahmet; Bilgili, Bilgehan
    A new subspecies in sect. Jacea (Mill.) DC., Centaurea cassia Boiss. subsp. dumanii M. Din double dagger, A. Duran & B. Bilgili subsp. nov., collected by the authors from South Anatolia, is described and illustrated. The new subspecies is restricted to Abies cilicica (Ant. & Kotschy) Carr. subsp. cilicica forest above Goller YaylasA +/- (C6 Adana-Kozan). Diagnostic morphological characters from C. cassia subsp. cassia are discussed. The ecology, biogeography and conservation status of the new taxon are also presented.

    Teucrium chamaedrys L. subsp. tauricolum Rech. fil. ve T. scordium L. subsp. scordioides (Schreber) Maire & Petitmengin (Labiatae) taksonları üzerinde anatomik ve mikromorfolojik çalışmalar
    (2007) Dinç, Muhittin; Doğu, Süleyman; Bilgili, Bilgehan; Duran, Ahmet
    Bu çalışmada, Teucrium L. cinsinde birbirine yakın akrabalık gösteren Scordium Boiss. ve Chamaedrys Benth. seksiyonlarına mensup T. chamaedrys L. subsp. tauricolum Rech. fil. ve T. scordium L. subsp. scordioides (Schreber) Maire & Petitmengin taksonlarının gövde ve yaprak anatomisi ile fındıkçık mikromorfolojisi incelenmiştir. Sonuçlara göre, her iki taksondaki gövde anatomisi, Labiatae familyasının genel özelliklerini sergilemektedir. Her iki taksonda çok hücreli salgısız tüylere rastlanırken, salgılı tüyler T. scordium subsp. scordioides’de her zaman, T. chamaedrys subsp. tauricolum’da bazen bulunmaktadır. Salgılı tüyler, T. chamaedrys subsp. tauricolum’da kısa ve 1-2 sap hücreli, T. scordium subsp. scordioides’de uzun ve 3-5 sap hücrelidir. T. chamaedrys subsp. tauricolum yaprağında mezofil kalın ve dorsiventral, T. scordium subsp. scordioides’de mezofil oldukça ince ve izolateraldir. T. scordium subsp. scordioides’de yapraklar hiposutomatik ve üst epidermal hücreler siferokıristalli, T. chamaedrys subsp. tauricolum’da yapraklar amfisutomatik ve üst epidermal hücreler siferokıristalsizdir. Her iki türde sutomalar anomositik olup T. chamaedrys subsp. tauricolum’da kıseromorf tipdeyken, T. scordium subsp. scordioides’de mezomorf tiptedir. Işık ve taramalı elekturon mikroskobu (SEM) çalışmalarına göre, fındıkçıkların büyüklüğü, şekli ve tüylenmesi iki taksonda farklılıklar göstermektedir. Elde edilen verilerin Scordium ve Chamaedrys seksiyonlarının sınırlandırılmasındaki taksonomik değeri tartışılmıştır.
