Tripleurospermum transcaucasicum (Manden.) Pobed (Asteraceae, Anthemideae) is newly recorded from East Azarbayejan Provice, NW Iran. It is morphologically similar to T. caucasicum (Willd.) Hayek and T. monticolum (Boiss. & A.Huet) Bornm. The morphological and anatomical diagnostic characters of new record are compared with closely related species. The geographical distribution of new records and related species in Iran are presented.
Anthemis ekicii (Asteraceae), a new species from Turkey
TURKISH JOURNAL OF BOTANY, 2020
Introduction Anthemis L. (Asteraceae) is one of the largest genus of the tribe Anthemideae which consists of nearly 175 species worldwide. It is distributed widely across Europe, SouthWest Asia, North and East Africa (Oberprieler et al., 2007). SouthWest Asia is one of the genetics centres of the genus Anthemis (Oberprieler, 1998). According to the "Flora of Turkey" it has been divided into three sections (Grierson and Yavin, 1975). These are Anthemis, Maruta (Cass.) Gris, and Cota (J.Gay) Rupr. The sect. Anthemis is separated from the other sections by oblong or oblanceolate paleae and ± angular or squarish achenes. Moreover, the capitula and leaf shapes have diagnostic characters for separating the sections. It includes 52 taxa (27 species, 3 subspecies, and 22 varieties) in Turkey (Grierson and Yavin, 1975). A. sect. Maruta, which is represented by 6 species in Turkey (Yavin, 1970), is separated from sect. Anthemis by the linear-lanceolate or subulate paleae and by sharp point terete achenes. A. sect. Cota includes 22 taxa (15 species, 1 subspecies, and 6 varieties) and 1 doubtfully recorded taxon in Turkey. More recently, generic and infrageneric changes in Anthemis (s.l.) were carried out and A. sect.

This study concerns the evaluation of micromorphological and anatomical characters of fruit (achenecypsela) in 12 Turkish endemic Tripleurospermum taxa using multivariate analyses (cluster analysis, principal component analysis, one-way analysis of variance). Pericarp in all taxa examined is mainly composed of several layers of parenchymatous and sclerenchymatous cells with one vascular bundle in each rib. In the achene, the thickness and width of lateral and adaxial ribs with presence or absence of a slime envelope have high taxonomic value for Tripleurospermum at interspecific levels. The slime envelope formation is also correlated with ploidy levels and habitats of some taxa in Tripleurospermum.

A new halophytic species, Scorzonera tuzgoluensis A. Duran, B. Dogan & S. Makbul sp. nov. (Asteraceae), is described and illustrated from Tuz Lake, central Anatolia, Turkey. The new species grows in salt marshes, is endemic (confined to central Anatolia) and closely related to Scorzonera parviflora Jacq. and S. elata Boiss. The diagnostic morphological characters of these similar taxa are discussed. The ecology, biogeography and conservation status of the new species are also presented. The geographic distribution of the new species and related species is mapped.

A recent study of the Anthemis collections in the Balkans indicated that the taxa of the Anthemis macedonica group (A. macedonica subsp. macedonica, A. macedonica subsp. thracica, A. meteorica, A. orbelica) exhibit noteworthy morphological patterns not evaluated before. We applied morphometric approaches (principal components analysis, PCA; factor analysis on mixed data, FAMD) by considering 19 qualitative and 20 quantitative morphological characters, together with three ratios, in 26 populations of this group. Furthermore, the chromosome numbers and karyotype morphology were investigated in eight populations of the group, covering the taxa participating in the study. Our results revealed that the southernmost populations of the group represent a hitherto unknown species confined to serpentine: it is described here as Anthemis serpentinica Goula & Constantinidis. The morphological evidence supports the proximity of A. macedonica and A. orbelica, which would be better considered as s...
DIVERSITY OF CYPSELAR FEATURES IN SOME TAXA OF THE TRIBE ANTHEMIDEAE (ASTERACEAE)
IJPRBS, 2014
The cypselas of 11 species representing 8 genera as Achillea (2), Artemisia (1), Chamaemelum (1), Leucanthemum (1), Lonas (1), Matricaria (2), Tanacetum (1), Tripleurospermum (2) of the tribe Anthemideae have been examined morphologically. The significant morphological features of cypselas are the structure of carpopodium, corona, stylopodium, nature of ribs, surface marking and surface glands. Based on these diacritical cypselar features, a key is prepared for the identification of studied taxa.
The genus Halothamnus Jaub. & Spach (Chenopodiaceae) in Turkey
Turkish Journal of Botany, 2009
The semidesert taxon Halothamnus (Chenopodiaceae), which is confirmed to supersede the later Aellenia, is represented in Turkey by H. glaucus subsp. glaucus and H. hierochunticus. The former was known to occur in Kars and Ağri provinces but was found recently in Kayseri province as well. The latter is a new record for the flora of Turkey from Şanlıurfa province close to the Syrian border. Full descriptions of the genus and the species occurring in Turkey are given and the case of Aellenia is discussed. Images and distributional data including maps are provided.

The genus Astragalus L. (Fabaceae) has approximately 3000 taxa around the world. The genus is known to spread vigorously in cold, semiarid, and arid regions of the Old World (approximately 2400 species); in western regions of North America (about 450 species); and especially along the Andean Mountains in South America (about 100 species) (Maassoumi, 1998; Podlech and Zarre, 2013). Astragalus section Hymenostegis was first named by Bunge (1868-1869) in his revision, entitled "Generis Astragali species gerontogeae" under the subgenus Calyphysa. This section was revised by Rechinger et al. (1958) and then was included in the Flora of Turkey (Chamberlain and Matthews, 1970), Flora of USSR (Gontscharov, 1946) and Flora of Iraq (Townsend and Guest, 1974). The latest revision of the section was made by Zarre and Podlech (1996). Astragalus section Macrophyllium Boiss. was described first by Boissier (1872). Species assigned to the section Hymenostegis Bunge are spread throughout western Asia. The origin and the diversification center of this section are in Iran. The section is represented by 12 species (A. uraniolimneus Boiss. has been recorded as a doubtful species) in the Flora of Turkey volume 3 (Chamberlain and Matthews, 1970) and one extra species in volume 11 (Aytaç, 2000), a total of 13 species, four of which are endemic. In 2008, A. expetitus Maassoumi was published as a new record for Turkey by Podlech and Ekici (2008). According to Podlech and Zarre (2013), there are 54 species of sect. Hymenostegis in Iran, 14 in Turkey (including two endemics), three in Armenia, three in Azerbaijan, three in Iraq, and one in Georgia. The number of species assigned to A. sect. Macrophyllium in the flora of Turkey was thought to be nine, five of them being endemic (Chamberlain and Matthews, 1970). However, Zarre (2000) reduced the number of species in Turkey to five and the number of endemic species to one. Karaman and Aytaç (2013) published A. yukselii Karaman & Aytaç within the sect. Macrophyllium and increased the number of species to six, two of which are endemic to Turkey. The main objectives of this study were to clarify the taxonomic status of species belonging to Astragalus sect. Hymenocoleus Bunge, A. sect. Hymenostegis Bunge and A. sect. Macrophyllium Boiss. in Turkey based on field studies and herbarium surveys, and provide their emended descriptions, distributions, and ecology. 2. Materials and methods Since 2011, as part of a revision of the genus Astragalus, extensive field surveys were conducted in Turkey and a large number of specimens were collected. The specimens were all cross-checked with the various Astragalus accounts given in the relevant literature: Flora Uzbekistana
