Anatomy, palynology and floral diversity of the genus lamium l. (lamiaceae) in Turkey

Atalay, Zeynep
Lamium L. is the type genus of subfamily Lamioideae and the family Lamiaceae. Due to the absence of recognizable morphological characters, circumscription of the genus has undergone many changes through time. Turkey is the main biodiversity center of the genus with 36 taxa, 18 of which are endemic. Even though many genera in the subfamiliy Lamioideae have been subjected to various anatomical and micromorphological studies, a comprehensive investigation of the genus Lamium is still lacking. In the first part of this study, the anatomical (root, stem, leaf and petiole) and micromorphological (trichome and pollen morphology) characteristics of the Lamium species in Turkey are presented and their taxonomic implications are discussed. Together with gross morphology, such anatomical and micromorphological characters are proved to be taxonomically informative in the delimitation of certain infrageneric taxa. In the second part of this study, pollination biology and floral diversity of bee pollinated Lamium species; including Lamium villosifolium and L. album subsp. crinitum, which grow sympatrically in Isik Mountain, Kizilcahamam, were investigated. Two Lamium species are clearly adapted to pollination by Apiodea. Field and laboratory investigations revealed that co-occuring Lamium species are isolated from each other on the basis of morphological, mechanical and altitudinal aspects. The diversity of floral constructions increases the mechanical isolation by attracting different pollinators and by loading pollen on different parts of pollinator`s bodies. Change in the plant population density along the altitudinal gradient clearly triggered the pollinator assemblage variation.


Molecular phylogenetic position of Turkish abies (pinaceae) based on noncoding trn regions of chloroplast genome
Özdemir Değirmenci, Funda; Kaya, Zeki; Department of Biology (2011)
Abies is the second largest genus of family Pinaceae (after Pinus), consisting of about 51 species, all native to the Northern Hemisphere. There are six native taxa belonging to this genus growing in pure and mixed stands in Turkey. Abies cilicica subsp. isaurica, Abies nordmanniana subsp. bornmülleriana, Abies nordmanniana subsp. equi-trojani, Abies x olcayana are endemic and considered as lower risk (LR) species. To determine the genetic relationships in Turkish firs, 18 populations of different subspecie...
A Micromorphological study on the genus thymus lamiaceae in Turkey
Kütükalan, Damla; Doğan, Musa; Department of Biology (2019)
The genus Thymus L.(Lamiaceae) having its center of diversity in the Mediterranean distributed mainly in the Old World includes 45 species in Turkey. It belongs to the monophyletic subfamily Nepetoideae. In this study, epidermal micromorphological properties of 32 species of Thymus were examined by using scanning electron microscopy. Micromorphology of vegetative and floral organs were found to be providing good taxonomic features for understanding phylogeny of the genus.
A Numerical taxonomic study on the genus salvia l. (lamiaceae) in Turkey
Tiambeng, Deniz; Doğan, Musa; Department of Biology (2015)
Widely used a medicinal plant, Salvia L. is the largest genus in the family Lamiaceae, with over 1700 species found in Asia, Europe, Africa and the Americas. Within this genus, almost 100 species are recognized in Turkey. To date, however, no comprehensive infrageneric treatment of Salvia in Turkey exists. The objective of this study was to propose a more natural infrageneric classification of the genus Salvia in Turkey by using the numerical taxonomic approach developed by Sneath and Sokal in 1973. In this...
Morphology, anatomy and systematics of the genus Lathyrus l. (Legumınosae) in Central Anatolia, Turkey
Çildir, Hüseyin; Doğan, Musa; Department of Biology (2011)
In this study, morphology, anatomy and systematics of the Genus Lathyrus L. (Leguminosae) in Central Anatolia is presented. Comparative morphological characters and their variation in the Genus; Calyx, leaf, corolla and pollen grains micro-morphology of the species; Anatomy of the species; Ecology, endemism, phytogeography and IUCN threat categories of the species; Numerical analysis and Revision of the genus in Central Anatolia were conducted. For the first time the calyx, corolla and leaf micromorphology,...
Morphology, anatomy and systematics of the genus Salvia l. (Lamiaceae) in East and Southeast Anatolia, Turkey
Kahraman, Ahmet; Doğan, Musa; Department of Biology (2011)
This study aims to revise the genus Salvia L. in East and Southeast Anatolia in Turkey on the basis of macromorphological, anatomical, palynological, mericarp micro-morphological, ecological and numerical analysis. Towards achieving this goal, about 2500 specimens of Salvia were collected and examined during extensive field studies between July 2005 and June 2009. The materials collected by other researchers either from Turkey or abroad were also investigated. The results of the taxonomic revision show that...
