The recently published Gundelia purpurascens (Bornm.) Firat is shown to be a synonym of G. rosea. Gundelia tournefortii as understood by Al-Taey & Hossain (1984) can be assigned to G. tehranica Vitek & Noroozi. For the two species a preliminary distribution map is given.

The genus Gundelia is currently represented with 18 species, of which 16 are in Turkey. In genus Gundelia, the chromosomal data were reported from 12 species. In the present study, it is aimed to eliminate the deficiencies in the knowledge about chromosomal data of Gundelia species. In Genus Gundelia, only a single chromosome number had been detect...

Aim The mountainous regions in SW Asia harbour a high number of endemic species, many of which are restricted to the high‐elevation zone. The (sub)alpine habitats of the region are under particular threat due to global change, but their biodiversity hotspots and conservation status have not been investigated so far. Location Subalpine‐alpine habit...

Alpine habitats are characterized by a high rate of range restricted species compared to those of lower elevations. This is also the case for the Irano-Anatolian global biodiversity hotspot in South-West Asia, which is a mountainous area harbouring a high amount of endemic species. Using two quantitative approaches, Endemicity Analysis and Network-...

Asarina procumbens is reported as an addition to the alien flora of Austria. It is found locally naturalised in southern Styria.

Endemism in mountain ranges is considered to be the result of a number of factors, including restriction to refugia during Pleistocene climate fluctuations. However, isolation in glacial refugia cannot explain the origin of narrowly endemic taxa restricted to formerly heavily glaciated areas. Here, we investigate the phylogeny of two narrowly endem...

In the frames of our research on the genus Jurinea (Carduinae), the taxonomic status of some species has been checked. In this study, evidences are presented to support transferring the species Jurinea gedrosiaca to Tricholepis, a genus in Centaureinae. Furthermore, it is demonstrated that J. gedrosiaca is conspecific with T. edmondsonii described...

Vitek, E.: Gundelia (Compositae), from one to many species-an ignored diversity.-Fl. Medit. 28: 179-185. 2018.-ISSN: 1120-4052 printed, 2240-4538 online. For long time in scientific botany the genus Gundelia (Compositae) was treated with only one polymorphic species Gundelia tournefortii L. When finding new populations in Armenia it was realized, t...

The current investigations suggest the segregation of Jurinea cartilaginea from Jurinea, and its placement among Centaureinae. Molecular studies, based on the nuclear ribosomal internal transcribed spacers (nrITS), chromosome number data and pollen morphology, support the morphological results. Based on these results, J. cartilaginea is related to...

Astragalus Linnaeus (1753: 755) (Fabaceae), with about 240 sections and 3000 species, is the largest genus of flowering plants (Podlech & Zarre 2013). Sect. Hypoglottidei De Candolle (1825: 281) with 46 species is one of the taxonomically most problematic sections. The majority of these species grow in Turkey and Iran (Chamberlain & Matthews 1970;...

In Armenia, Nymphaea alba only occurs in a small area NW of Stepanavan. It is restricted to small lakes with a minimum depth of c. 2–3 m because in shallower lakes it may be out-competed by Typha or Schoenoplectus species.

The short career of Auguste R. Endrés as a botanical explorer, author and illustrator, is concentrated in just the few years that he spent in Costa Rica between the end of 1866 and the first months of 1874, with a brief parenthesis in Panama. In these seven years Endrés botanized throughout the country, devoting his main attention to the still unre...

Viola ×palmata L. (pro spec.), Viola sect Plagiostigma, originating from North AMERICA, was found in the centre of Vienna. It grows vigorously in stone fissures bearing many seeds developing from cleistogamous flowers, but no open‑pollinated flowers could be observed yet due to late season. The plants were tentatively identified by J. Danihelka, an...

When the orchid material collected in Costa Rica by A.R. Endres was typified by Pupulin et al. (2010), four taxa were overlooked. They are treated here. Masdevallia gracilenta and Polystachya cingulata are lectotypified.

Auguste R. Endrés botanized in Costa Rica between the end of 1866 and the first months of 1874, spending a short time in Panama. In these seven years he devoted his main attention to the still unrevealed richness of Costa Rican Orchidaceae. The results of his activity have still to be properly evaluated, but his contributions to the botany of Costa...
