Cousinia elymaitica (Cardueae, Asteraceae) a new species from west of Iran
Cousinia elymaitica, which has been collected from western Iran, is described in this paper as a new species. This new species has been assigned to the sect. Pugioniferae on the basis of its habit, purple corolla and decurrent leaves. Its closest related species is C. macroptera. A distribution map and an illustration of the related specimens have also been provided.
متن کاملNovelties in Cardueae (Asteraceae)
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 and, therefore, transferred to the genus Karvan...

متن کاملNew chromosome counts in some plant species from east and south-east Iran
In this study, we investigated the chromosome numbers of some endemic species distributed in East and South-East Iran. The mitotic chromosome counts were presented for the first time for six species in three angiosperm families including: Linaria iranica (2n=12), Nanorrhinum campyloceras (2n=18), Chaenorhinum grossecostatum (2n=24) (Plantaginaceae), Gaillonia bruguieri (Rubiaceae) (2n=22), Nepe...
