| The genus Quercus L. (Fagaceae) is one of the most diversified groups of temperate trees with more than 500 species distributed worldwide. Quercus section Quercus, the white oaks, has the greatest number of species and has the widest distribution occurring in Asia, Europe, North Africa, and North and Central America. Oak species with lobed leaves in the Zagros forests belong to the sect. Quercus. In previous regional taxonomic accounts, Djavanchir and Menitsky identified six and two taxa of sect. Quercus in Zagros forests, respectively. We studied a great number of specimens of white oaks from the Zagros forests and assigned them to previously described taxa. Then we compared them to digital images of type specimens provided by the Royal Botanic Garden Edinburgh and National Botanic Garden of Belgium. Twenty-three qualitative and quantitative characters of leaves and acorns were examined. Cluster Analysis (CA) of data showed that morphology of leaves, micro-morphology of foliar trichomes in combination with acorn morphology are valuable in species distinction. In addition, our results showed that foliar trichomes have little value in separation of taxa at species level, whereas leaf shape proved to be a better tool for discrimination of species. According to the observations and our findings, the following taxa of white oaks with lobate leaves exist in the Zagros forests: Quercus robur L. subsp. pedunculiflora (K. Koch) Menitsky, Q. robur L. subsp. robur, Q. petraea subsp. pinnatiloba(K. Koch) Menitsky and Q. infectoria subsp. veneris (A. Kern.) Meikle. Q. robur L. subsp. robur and Q. petraea subsp. pinnatiloba(K. Koch) Menitsky are reported as new records for the flora of Iran. | ||

| چکیده [English] | ||
| جنس بلوط دارای حدود 500 گونه در سراسر جهان می‌باشد. گروه بلوط‌های با برگ لوب‌دار دارای بیشترین گونه نسبت به سایر گروهها ی این جنس می باشد. در این پروژه پراکنش گونه‌های بلوط با برگ لوب‌دار در رشته کوه زاگرس مورد مطالعه قرار گرفته است. جوانشیر 6 گونه و مینسکی 2 گونه از این گروه را برای زاگرس بیان کرده اند. نمونه‌ها بر اساس کارهای قبلی صورت گرفته، فلور سایر کشورها، عکس های دیجیتال از هرباریومهای باغ گیاهشناسی ادینبورا، باغ گیاه شناسی بلژیک و انجام مطالعات مورفولوژیک موردشناسایی قرار گرفتند. در این مطالعه 23 صفت کمی و کیفی برگ، کرکها و پیاله مورد مطالعه قرار گرفت. آنالیز خوشه‌ای نمونه‌ها نشان داد که صفات برگ در این گروه نقش مهم و اساسی در جدا کردن گونه‌ها دارند و نقش کرکها در جدا کردن گونه‌ها کم رنگ می‌باشد. بر اساس مشاهدات و یافته‌های ما چهار تاکسون زیر از این گروه در رشته کوه زاگرس حضور دارند. Quercus robur L. subsp. pedunculiflora (K. Koch) Menitsky, Q. robur L. subsp. robur, Q. petraea subsp. pinnatiloba (K. Koch) Menitsky and Q. infectoria subsp. veneris (A. Kern.) Meikle. و در نهایت دو تاکسون زیر برای اولین بار از فلور ایران گزارش می‌گردند Quercus robur L. subsp. robur and Q. petraea subsp. pinnatiloba (K. Koch) Menitsky | ||
