    No full text
    Turkey is among the richest countries in the world in terms of plant diversity. The aim of this paper is to show diversity of the petaloid and bulbous plants. which belong to monocotyledones. According to Flora of Turkey and its supplements, the number of species of bulbous monocotyledones is around 688, of which 244 are endemic (endemism 35.4%). According to the statistical data of Turkish flowering plants based on the published records, only 15% of the flora have information about chromosome counts, although bulbous monocots percentage is higher at 58%. Fritillaria and Tulipa are stable genera as regards chromosome numbers with 2n = 24 and karyotype on the other hand, the most variable genera are Crocus (2n = 6, 8, 10, 12, 14, 16, 18, 20, 22, 26, 28, 30, 70) and Ornithogalum (2n = 12, 14 16, 18, 20, 21 24, 27, 28, 32. 40, 45 54, 60, 80)

    Allium purpureoviride M. Koyuncu & I. Genc (sect. Melanocrommyum) is described as a new species from east Anatolia, Turkey. The new species is closely related to A. rothii Zucc. from Israel and some characters of the new taxon show similarity with A. cyrilli Ten. and A. asclepiadeum Bornm. The morphological characters of the related taxa are discussed and the distribution of the taxa is mapped. The diploid chromosome number is 2n =?16

    MORPHOLOGICAL AND ANATOMICAL CHARACTERISTICS OF Veronica turrilliana Stoj. & Stef. (Serophulariaceae): THE RARE AND THREATENED SPECIES OF TURKEY

    No full text
    Veronica turrilliana Stoj. & Stef. is a Balkan endemic species widely distributed in Northern part of European Turkey. It is listed as threatened species in App. I of the Bern Convention. The species was described by N. Stojanov and B. Stefanov in 1923 from material collected from the Strandzha Mountains in Southeast Bulgaria. In this paper, morphological descriptive characteristics of V. turrilliana, its distribution and approaches on threats and conservation is given. Also anatomical properties of its aerial parts have been presented

    A hydrodistilled essential oil from fruits of Cachrysalpina,was analyzed by GUMS. Twenty-nine compounds representing 98% of the oil were identified with alpha-humulene (33.1%), p-cymene (9.3%). alpha-phellandrene (9.1%) germacrene D (8.2%) and alpha-pinene (6.3%) as main constituents

    Allium istanbulense, a new autumnal species of A. sect. Codonoprasum (Amaryllidaceae) from Turkey and its taxonomic position among allied species

    No full text
    Allium istanbulense, a new species of Allium sect. Codonoprasum, is described and illustrated from Istanbul surroundings (European Turkey). It is a late-flowering diploid species (2n = 16), occurring in the undergrowth of oak or pine woods mainly on sandy or incoherent soils. Its morphology, karyology, leaf anatomy, seed micromorphology, ecology, conservation status and taxonomic relationships are examined. A taxonomic comparison with the most allied late flowering species of sect. Codonoprasum and identification keys of the group are also provided
