    MORPHOLOGICAL, ANATOMICAL AND CYTOLOGICAL STUDIES ON ENDEMIC LAMIUM PISIDICUM
    Baran, P; Özdemir, C
    Morphological and anatomical features of endemic Lamium pisidicum R. Mill (Lamiaceae) were studied. L. pisidicum is a perennial with a taproot system. The stem is ascending to erect in position and clearly quadrangular in shape. The leaves are ovate to broadly ovate or rarely reniform in shape. Verticillasters are 2-14 flowered. The corolla is pinkish-purple to mauve and the upper lip is deeply bifid and the tube is without annulus. The stigma is bifid. The stamens are didynamus. Anatomically, spring and autumn woods are distinguishable in the root structure of the perennial taxon. There is a well-developed collenchymatous layer at the corners of the stem and a pith hollow in the centre. In the petiole cross-section, 1-2 layered collenchyma layer is located at the corners while 3 central vascular bundles are located in the middle and 1 vascular bundle at the petiolar wings. The leaf is bifacial. Each anther is of two thecae and each theca is of 2 pollen sacs. Pollen type is trizonocolpate and pollen shape is spheroidal. The cross-section of seed is triangular. Glandular hairs distributed on the plant species are classified into 2 main types, peltate and capitate. Furthermore, capitate glandular hairs are seperated into 2 types, type I and type II. Somatic chromosomes are counted as 2n=18 for the first time in this study.

    Structural investigation of the glandular trichomes of endemic Salvia smyrnea L.
    Baran, P; Aktas, K; Özdemir, C
    The morphology, anatomy and distribution of glandular trichomes on the aerial organs of Salvia smyrnea L. endemic to Turkey have been investigated with light microscopy (LM) and scanning electron microscopy (SEM). This species is evaluated in endangered (EN) category. Two morphologically distinct types of glandular trichomes were determined. Various types of capitate glandular trichomes consist of a 1-4 celled base, a 1-8 stalk celled or no stalk and a uni- or bicellular head. In capitate trichomes the neck cell that has an important role especially for xeromorfic plants, acting to prevent the backflow of secreted substance through the apoplast, has been distinctively observed in the investigated species. The capitate trichomes were present abundantly on all aerial organs of S. smyrnea. Peltate glandular trichomes had a large secretory head comprising 1-2 central and 4,6, 8-10 peripheral cells. This study pointed out that S. smyrnea was of rich glandular trichomes in point of diversity and quantity. (C) 2010 SAAB. Published by Elsevier B.V. All rights reserved.

    Baran, P; Özdemir, C; Aktas, K
    The morphology, anatomy and distribution of glandular trichomes on the aerial organs of Salvia argentea L. has been investigated. Two morphologically distinct types of glandular trichomes were determined. Capitate glandular trichomes forming a base 1-7 celled, a stalk 1-5 celled or no stalk and a head uni- or bicellular had various types. In capitate trichomes, the neck cell that has an important role especially for xeroformic plants, acting to prevent the backflow of secreted substance through the apoplast has been distinctively observed in the investigated species. The capitate trichomes were present abundantly on all aerial organs of S. argentea. Peltate glandular trichomes had a large secretory head forming 1-5, 8 central and 8-10, 12, 14 peripheral cells. Peltate trichomes are present on all aerial organs, except petiole, being the most abundant on calyx and corolla. Results were shown by tables and photographs.

    Aktas, K; Altan, Y; Özdemir, C; Baran, P; Garnatje, T
    Pollen morphology of 10 taxa from Turkey, four of them endemic, belonging to the genus Petrorhagia (Caryophyllaceae), P. alpina subsp. alpina, P. alpina subsp. olympica, P. cretica, P. dubia, P. hispidula, P. lycica, P. pamphylica, P. peroninii, P. prolifera and P. saxifraga, has been investigated using light (LM) and scanning electron (SEM) microscopy. Pollen morphology differences among these taxa have been determined. The pollen type of investigated taxa is polyporate (12-22-porate), sphaeroidal, the exine exhibits a tectate structure and a microechinate ornamentation. Petrorhagia alpina subsp. alpina has the smallest pollen grain diameter (18.57 mu m) and P. dubia the largest one (37.80 mu m). The number of pores ranges from 12 (in P. dubia and P. saxifraga) to 22 (in P. alpina subsp. alpina and P. alpina subsp. olympica and P. hispidula) with a minimum pore diameter of 2.37 mu m in P. alpina subsp. alpina and a maximum pore diameter of 4.23 mu m in P. peroninii. The exine thickness ranges from 1.73 mu m in P. saxifraga to 3.78 mu m in P. pamphylica. In this study, the systematic implications are discussed in the light of palynological results.

    Aktas, K; Özdemir, C; Özkan, M; Baran, P
    In this presented work. the pollen morphologies of twenty-one taxa. nine of them endemic from Turkey, belonging to the genus Salvia (Lamiaceae: subfamily Nepetoideae: tribe Mentheae: sub-tribe Salviinae), S aethiopis L., S argentea L., S. aytachii Vural & Adiguzel, S. blepharochlaena Hedge & Hub.-Mor., S. cadmica Boiss., S. ceratophylla L., S cryptantha Montbret & Aucher, S. frigida Boiss., S. fructicosa Miller, S. halophile Hedge, S. napifolia Jacq., S. microstegia Boiss. & Bal., S. recognita Fisch. & Mey. S sclarea L., S smyrnaea Boiss. S suffruticosa Montbret & Aucher, S. tchihatcheffii (Fisch. & Mey.) Boiss., S. tometosa Bertol, S. verbenaca L., S viridis L., and S wiedemanni Boiss. and collected throughout the Turkey, have been intensively studied by using light (LM) and a scanning electron (SEM) microscopy. The objectives of this study are to investigate the pollen morphologies of twenty-one taxa of Turkish Salvia (nine of which are endemic) and to present similar and different characteristics of the taxa. The investigated whole pollen grains had a structure of both isopolar and radial symmetry. Overall, types of aperture were mostly hexacolpate, but it was also determined that the aperture type of S. viridis was both hexacolpate and octacolpate. The pollen grains had characteristic shapes of spheroidal, suboblate, prolate and subprolate. The exine ornamentation was bireticulate and reticulate-perforate. It was determined by the results of palynological studies that pollen morphology changed amongst these studied taxa. As a conclusion, the results of the present study show that palynological characters such as pollen shape, polar axis length (P), equatorial axis length (E). aperture numbers and types and exine ornamentation, exhibit remarkable differences amongst the studied taxa.
