A taxonomic revision of the Sempervivum davisii complex (Crassulaceae)

Eggli, Urs
A revision of four Sempervivum species (S. artvinense, S. brevipetalum, S. davisii and S. furseorum) based on field observation and examination of herbarium specimens (including the type specimens of all names) is presented. Examination of critical diagnostic characters showed that S. artvinense, S. brevipetalum and S. furseorum fall within the variability of S. davisii and should be subsumed as synonyms under this name. Sempervivum furseorum shows minor but consistent morphological and ecological differences as well as a disjunct distribution and is therefore treated as S. davisii ssp. furseorum. Moreover, an amended and expanded description of the species is presented, with notes on distribution, phenology and ecology.


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\...
A new species of Acantholimon Boiss. sect. Glumaria Boiss. (Plumbaginaceae) from Elazig, Turkey
Dogan, M; Akaydin, G (Oxford University Press (OUP), 2005-11-01)
A new species, Acantholimon evrenii sp. nov. is described and illustrated for the first time in sect. Glumaria from Turkey. The species is confined to B7 Elazig in East Anatolia where it grows on rocky mountain steppes. The diagnostic morphological characters from closely related species are given, along with a discussion dealing with its taxonomic relationship. Its conservation status is indicated. A revised key is also provided for the Acantholimon species with heterophyllous leaves, two or more flowered ...
Three new species with two flowered spikelets in Acantholimon (Plumbaginaceae) from East Anatolia, Turkey
Doğan, Musa (Oxford University Press (OUP), 2004-04-01)
Three new species, Acantholimon bashkaleicum sp. nov., Acantholimon artosense sp. nov. and Acantholimon hoshapicum sp. nov. (Plumbaginaceae) are described and illustrated. The species are all confined to B9/B10 Van Province in East Anatolia where they grow either on calcareous mountain slopes or on mountain steppes. Diagnostic morphological characteristics from the closely related species are given, along with a discussion dealing with their taxonomic relationships, and their conservation statuses are point...
Pollen morphology of some taxa of Vicia L. subgenus Vicia (Fabaceae) from Turkey
KAHRAMAN, AHMET; Binzat, Okan Kaan; Doğan, Musa (Springer Science and Business Media LLC, 2013-11-01)
In this study, the pollen morphology of 11 taxa belonging to Atossa (Alef.) Asch. & Graebner, Hypechusa (Alef.) Asch. & Graebner, Peregrinae Kupicha, Wiggersia (Alef.) Maxted, Vicia L. and Narbonensis (Radzhi) Maxted sections of the genus Vicia L. subgenus Vicia (Fabeae, Fabaceae) naturally growing in Turkey has been studied using Light Microscopy (LM) and Scanning Electron Microscopy (SEM) to evaluate the taxonomic relevance of pollen characters. Twelve morphometric characters are analysed with one-way ana...
A numerical taxonomic study of the genus Acantholimon Boiss Plumbaginaceae in Ankara Province Turkey
MUVAFFAK, Aslı; Doğan, Musa; Bilgin, Cemal Can (Laser Pages Publishing Ltd., 2001-01-01)
This study examines whether a satisfactory classification of Acantholimon Boiss. (Plumbaginaceae) species found in Ankara province (Turkey) can be obtained from phenctic clustering based on external vegetative and floral morphological characters of both herbarium and collected specimens, The study is on the following species: A. venustum Boiss., A, halophilium Bokhari., A. acerosum (Willd.) Boiss., A. kotschyi (Jaub. & Spach) Boiss., A. confertiflorum Bokhari., A. glumaceum (Jaub. & Spach) Boiss., A. casare...
