A conspectus of Scorzonera s.l. in Turkey

Abstract

The genus Scorzonera L. (Asteraceae), with about 160 species belonging to the subtribe Scorzonerinae Dumort. of the tribe Cichorieae, is widespread in the more arid regions of Eurasia and northern Africa (Bremer and Anderberg, 1994;Nazarova, 1997).After the genus Scorzonera s.str. was revised by Chamberlain (1975) for the Flora of Turkey, many new species have been recorded from Turkey. The classification of the genus has been highly controversial (Nazarova, 1997;Mavrodiev et al., 2004), and because of this different taxonomic treatments have been used in the floras. Starting with De Candolle (1805), frequently Scorzonera species with a conspicuous cylindric carpopodium were placed under a separate genus,

Delimitation of Iranian species of Scorzonera subg. Podospermum and S. subg. Pseudopodospermum (Asteraceae, Cichorieae) based on morphological and molecular data

“…Pseudopodosper mum. This taxonomic concept is in accordance with the following studies: Lipschitz (1964), Rechinger (1977), Safavi (2013), and Coşkunçelebı & al. (2015).…”

“…2009a. Instead of splitting Scorzonera into different genera, some workers (Lipschitz 1964;Rechinger 1977;Safavi 2013;Coşkunçelebı & al. 2015) recognized three subgenera: S. subg.…”

Cytogenetic studies on some Scorzonera L. s.l. (Asteraceae) taxa from Turkey

“…Furthermore, according to this revisional study, S. inaequiscapa (x = 7) and S. semicana (x = 7) should also be transferred under the subgenus Pseudopodospermum (x = 7). The basic chromosome numbers of these 2 taxa also support the transfer of the last 2 taxa under the subgenus Pseudopodospermum (Coşkunçelebi et al, 2015). In our study, chromosome numbers of 32 Scorzonera taxa were reported.…”

“…Coşkunçelebi et al (2015) reported that S. hieraciifolia (x = 7) should be transferred to subgenus Podospermum (x = 7), based on morphological, anatomical, and other studies. Chromosome number is in accordance with the basic chromosome number of Podospermum and thus supports this opinion.…”

A new species of Cirsium sect. Epitrachys (Asteraceae: Cardueae)from the south of Turkey

“…C. bozkirensis is different from C. cephalotes by its stem indumentum arachnoid with a few multicellular hairs to tomentose hairs (not many multicellular hairs) ( Figures 4A, 4B, 4D, and 4E) and it differs from C. pugnax by its stems densely arachnoid to tomentose with a few multicellular hairs (not only sparsely arachnoid) ( Figures 4B 4C, 4E, and 4F). Furthermore, the setae on the leaf are different in terms of density ( Figures 5A-5F) The morphological characters of the cypsela are quite useful for the delimitation of different taxa at both the generic and species level within the genera of Asteraceae, such as Scorzonera L., Lactuca L., Cicerbita Wallr., Prenanthes L., Achillea L., and Carduus L. (Akçin and Akçin, 2014;Köstekçi and Arabacı, 2014;Abid and Qaiser, 2015;Coşkunçelebi et al, 2015Coşkunçelebi et al, , 2016Aytaç et al, 2016). In addition, the macro-and micromorphological features of the cypselae of Cirsium taxa can be used as distinguishing characteristics.…”
