    Özdemir, C; Akyol, Y; Alçitepe, E
    Morphological and anatomical characteristics of Crocus danfordiae Maw and C. fleischeri Gay which are endemic to small areas of Turkey were investigated. C fleischeri has flowers with stained purple at base and on tube, C. danfordiae has anthers with black basal lobes at it's base. These properties are characteristics for the investigated species. In anatomical studies, cross section of C. danfordiae and C. fleischeri root, stein and leaf parts were examined and demonstrated.

    NEW COMBINATIONS IN CAMPANULA SECT. QUINQUELOCULARES FROM TURKEY
    Alçitepe, E
    Campanula lyrata Lam. and C. sorgerae Phitos, C. betonicifolia Sm. and C. karadjana Bocquet are taxonomically problematic. In the present study, their morphology, leaf surface anatomy and palynological characters were thoroughly analysed. Photographs, illustrations, useful differential morphological characters, pollen structure and a distribution map obtained or developed in the course of the study were presented. Problems of nomenclature and synonymy were also discussed. A new combination and status nov. Viz., C. betonicifolia subsp. karadjana (Bocquet) Alcitepe comb.& stat.nova has been proposed. C. sorgerae Phitos was reduced to a synonymy of C. lyrata Lam. subsp. lyrata.

    Morphological, anatomical and palynological studies on Asyneuma michauxioides (Campanulaceae)
    Alçitepe, E
    The morphological, anatomical and palynological features of Asyneuma michauxioides (Boiss.) Damboldt (Campanulaceae) were investigated. This species is an East Mediterranean Floristic Element and an endemic in Turkey. In anatomical studies, cross-sections of the root and stem were examined and demonstrated by photographs. It has conspicuous endodermis in which the Casparian bands are indistinct in the stem. According to the result of this study, it was found that pollen grain of this taxon was 3-porate sometimes 4-porate and oblate-spheroidal. Its structure was tectate and sculpture was small granules and pits with densely spaced spinules. The seeds of the taxon were eliptic to ovate in shape, laterally compressed, brown to light brown in colour, glabrous and shiny.

    Some soil parameters in Campanula species (sect. Quinqueloculares) from Mediterranean climate areas in Turkey
    Alçitepe, E; Everest, A; Sungur, MA
    Ten soil samples from the Mediterranean region of Turkey were analysed to evaluate the ecology of Campanula species. Most soils in the research area were alkaline and salt content was high. Degrees of saturation were considered normal in all the soil samples and, generally, total nitrogen values were low. For all samples, the total concentration of macro-and micro-elements were determined. There were significant differences in concentration of Mg, P, N in the upper zone of the soils, and in pH, salinity, lime, saturation (%) between species. There were no significant differences in the concentrations of Ca, Cu, Fe, K, Mn, Na, and Zn between the upper and lower zones.

    THE MORPHOLOGICAL, ANATOMICAL AND PALYNOLOGICAL PROPERTIES OF ENDEMIC HAPLOPHYLLUM MEGALANTHUM BORNM. (RUTACEAE)
    Akyol, Y; Alçitepe, E; Özdemir, C
    Haplophyllum megalanthum Bornm. which has been included in the list of EN (Endangered) the IUCN threat category was investigated morphologically, anatomically and palynological. Some different morphological characteristics determined from its description given in the Flora of Turkey for the species. The pollen grains were radial symmetrical, isopolar, tricolporate. Pollen shape differed from subprolate to spheroidal.

    STUDIES ON SEED MORPHOLOGY OF CAMPANULA L. SECTION QUINQUELOCULARES (BOISS.) PHITOS (CAMPANULACEAE) IN TURKEY
    Alçitepe, E
    Morphological features of seeds of 9 species of Campanula L., section Quinqueloculares (Boiss.) Phitos (Campanulaceae) which are distributed in Turkey were investigated by scanning electron microscopy (SEM). Characteristics of the seeds and their surface are described and compared. Two main types and two subtypes of surface ornamentation patterns are observed. These can be considered as diagnostic characters.

    Comparative pollen morphology of sect. Quinqueloculares (Campanulaceae) in Turkey
    Alçitepe, E
    The pollen morphology of Turkish species belonging to sect. Quinqueloculares (Boiss.) Phitos (Campanulaceae) were investigated with a light microscope (LM) and scanning electron microscope (SEM). All examined species are endemic, except Campanula crispa Lam. According to the results of this study, pollen grains of the examined taxa were triporate and spheroidal. Their sculpture was spinose and baculate (C. crispa Lam.); spinulose and microperforate (C. tomentosa Lam.); microperforate (C. vardariana Bocquet) or more commonly, microechinate (C. iconia Phitos, C. lyrata Lam. subsp. lyrata, C. hagielia Boiss., C. sorgerae Phitos, C. betonicifolia SM., C. karadjana Bocquet, C. telmessi Hub.-Mor. & Phitos, C. davisii Turrill).

    A Morphological and Anatomical Study on Endemic Campanula davisii Turrill (Campanulaceae) in Turkey
    Alçitepe, E
    Campanula davisii Turrill is an species endemic with a narrow distribution to Turkey and east Mediterranean Phytogeographic Region. The morphological and anatomical properties of this species were investigated. When morphological measurements of investigated species are compared with Flora of Turkey, the some differences have determined. Eventually, full description and illustration of these species was given. The anatomical studies on cross-sections of the root, stem, leaves and surface sections of leaves were presented. Cambium located under phloem was 2-3 layered and uncontinuous in root. Underneath the cortex parenchyma is endodermis, which consists of 1 layer and distinguishably in stem. Leaves is bifacial. Stomata are located both on the surface.

    A Morphological and Anatomical Study on Scilla bifolia L. (Liliaceae)
    Özdemir, C; Alçitepe, E
    In this study, morphological and anatomical properties of Scilla bifolia L. were investigated. The results were compared with previous studies. When morphological measurements of investigated species are compared with Flora of Turkey, some differences and similarities were observed. In anatomical study, root and scape demonstrated typical monocotil structure. The bundles of scape have the shape of a single ring. Raphide crystals which have systematical importance were present in root and leaf while not in scape.

    REMARKS USING THE SEM METHOD SPECIES SEEDS OF Gentiana OCCURRING IN TURKEY
    Alçitepe, E; Erken, S; Gülbag, F; Özzambak, ME
    Seeds of eleven perennial Gentiana collected from Turkey were analyzed using the SEM method. Other species excluding G. septemfida, G. boissieri, G. gelida were studied for the first time. They were identified and compared in terms of seed characteristics and surface ornamentations. Major characteristics including the outer periclinal walls of testa, sculpting of inner periclinal walls, seed shape, seed and testa cell, wing cell size, thickness of testa wall and seed shape have been proposed for Turkey Gentiana. They are divided into different types, such as no wing, chalazal wing, incomplete discoid wing, complete discoid wing according to the outer periclinal walls of testa. Considering primary sculpting of seeds, irregularly striate and shallowly reticulate type is observed. Anticlinal walls of G. olivieri, G. boissieri and G. gelida are curved, while others are straight. G. lutea has the largest mean seed (4.20 x 4.40 mm), while G. cruciata (0.67 x 0.60 mm) and G. olivieri have the smallest mean seeds (0.67 x 0.67 mm). Seed micromorphology can be used together with morphological character to form classifications in studied specimens for Gentiana genus.
