A Numerical taxonomic study on the genus salvia l. (lamiaceae) in Turkey

Tiambeng, Deniz
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 study, a total of 43 qualitative and quantitative macromorphological characters were described and measured from 96 taxa. Herbarium specimens collected in the field during the years 2005 to 2009 as part of the taxonomic revision of Salvia were used. UPGMA cluster analysis and Principal Coordinates Analysis (PCO) were performed to determine the phenetic relationships among Turkish Salvia species. Additionally, a Principal Components Analysis (PCA) was conducted to distinguish the most useful characters for the infrageneric delimitation of the taxa. All analyses were carried out using the MVSP (version 3.2) computer program. The results of the cluster analysis and PCO reveal five distinct infrageneric clusters under two major groups. Based on the PCA, 25 vegetative and reproductive morphological characters were found to be diagnostic for the delimitation of Salvia into the five infrageneric clusters. Furthermore, the results of this study are not wholly consistent with Bentham’s sections, but instead are more congruent with the findings of recent molecular phylogenetic studies.


A cytomorphological study in some taxa of the genus Salvia L. (Lamiaceae)
MARTİN, ESRA; Cetin, Ozlem; Kahraman, Ahmet; Celep, Ferhat; Doğan, Musa (2011-07-01)
The taxa of the genus Salvia L. (Lamiaceae) used in this study were collected from their natural habitats in Turkey. In this paper, the number, size and morphology of somatic chromosomes of 22 Turkish taxa of Salvia, namely S. bracteata Banks & Sol., S. fruticosa Mill., S. huberi Hedge, S. hydrangea DC. ex Benth., S. nemorosa L. and S. pomifera L. (2n=14), S. adenocaulon P.H. Davis and S. aucheri Benth. subsp. canescens Boiss. & Heldr., (2n=18), S. argentea L., S. frigida Boiss., S. palestina Benth., S. poc...
Molecular phylogenetics of Turkish Salix L. species
Acar, Pelin; Kaya, Zeki; Department of Biology (2017)
Chloroplast (trnT-F, matK and rbcL) and nuclear genome (ITS) regions were used to explore the evolutionary relationships of Salix species which are native to Turkey. Morphological analysis with the utilization of Principal Component Analysis (PCA) was also carried out. Such a combined sequence data from cpDNA and nrDNA genes enabled reliable subgenus-level classification of Turkish willows (subgenus Salix and Vetrix). Morphological and genetic results agree with traditional taxonomic concepts in clustering ...
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 new taxon of the genus Salvia (Lamiaceae) from Turkey
CELEP, FERHAT; Kahraman, Ahmet; Doğan, Musa (Botanical Garden Meise, 2011-01-01)
Background and aims Turkey is one of the major centers of diversity for Salvia, with 97 species of which 54% are endemic. The aims of this study are to give detailed taxonomical, morphological and ecological accounts of S. cadmica and S. smyrnaea.
Comparative molecular phylogenetics of Astragalus L. sections from Turkey with New World Astragalus species using nrDNA ITS sequences
Dizkirici, Ayten; EKİCİ, MURAT; Kaya, Zeki (Springer Science and Business Media LLC, 2014-01-01)
Comparative molecular phylogenetic study using nrDNA internal transcribed spacer region (ITS) sequences was carried out on species from three Astragalus L. (Fabaceae) sections from Turkey (Old World species) and the New World. A total of 56 taxa (179 accessions) including 30 species from Incani DC., 15 species from Hypoglottidei DC. and 11 species from Dissitiflori DC. section were used in the current study. The total length of the ITS region was 642 bp with 56 (8.7 %) parsimony-informative and 9 insertion\...
