چکیده
بر اساس این پژوهش، گونه Jurinea cartilaginea از سرده Jurinea جدا می شود و در زیرطایفه Centaureinae قرار می­گیرد. مطالعات مولکولی بر پایه نواحی هسته ای قابل رونویسی بین ژنی ریبوزومی (nrITS)، اطلاعات کروموزومی و مورفولوژی دانه گرده از مطالعات مورفولوژی حمایت می کنند. بر پایه این نتایج، J. cartilaginea به سرده Karvandarina نزدیک است و به این سرده منتقل می شود. به علت تفاوت در ویژگی های ریخت شناسی بین گونه مذکور و گونه Karvandarina aphylla، یک زیرسرده نو به نام Pseudojurinea شرح داده می­شود. همچنین مطالعات مولکولی از تک نیایی بودن سرده Jurinea حمایت می کنند.

چکیده English

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 Karvandarina. Due to the morphological characters differing from Karvanderina aphylla, a new subgenus, Pseudojurinea, is described. Molecular study also supports the monophyly of Jurinea.
