Novelties 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 کاملPhylogeny of Rhaponticum (Asteraceae, Cardueae-Centaureinae) and related genera inferred from nuclear and chloroplast DNA sequence data: taxonomic and biogeographic implications.
BACKGROUND AND AIMS The precise generic delimitation of the Rhaponticum group is not totally resolved. The lack of knowledge of the relationships between the basal genera of Centaureinae could imply that genera whose position is as yet unresolved could belong to the Rhaponticum group. On the other hand, the affinities among the genera that are considered as members of this group are not well kn...

متن کاملMorphological phylogenetic analysis of the genera Fragaria and Duchesnea in Iran
In this research phylogenetic relationships of the two genera Fragaria and Duchesnea, including four species ( Fragaria viridis, F. vesca, Duchesnea indica and D. chrysantha) and 2 of their closely related species (Potentilla reptans and P. micrantha) plus 2 Fillipendulla species ( representing outgroups) were carried out using morphological traits. Primarily, morphological evidences of 30 taxa...
