Abstract

Leaf anatomical characters of eight Iris L. taxa were compared and their relations were determined. Iris danfordiae, Iris celikii, Iris histrioides, Iris pamphylica and Iris histrio ssp. aintabensis are endemic to Turkey. Iris bakeriana, I. celikii, I. histrioides, I. pamphylica, I. histrio ssp. aintabensis and Iris histrio ssp. histrio have limited distribution in Turkey. The differences were seen especially in the mesophyl layer of the leaves. Mesophyll of I. reticulata and I. histrioides have an unifacial ensiform structure. Whereas mesophyll of the other investigated taxa have a bifacial ensiform structure. Leaf outline structure of all taxa are quadrangular structure (excluding I. bakeriana-terete structure). In mesophyll of leaves, hexagonal crystals (I. histrioides, I. danfordiae, I. bakeriana, I. histrio ssp. histrio, I. histrio ssp. aintabensis and I. pamphylica) and crystalline granules (I. reticulata, I. bakeriana, I. celikii, I. danfordiae, I. histrio ssp. histrio, I. histrio ssp. aintabensis and I. pamphylica) were found. The layer number of spongy and palisade parenchyma also vary among taxa. In the leaf anatomic characters of I. histrio ssp. histrio, I. histrio ssp. aintabensis, significant differences were not obseved. Based on the above leaves anatomical characters, we suggest that (1) I. reticulata and I. histrioides should be independent species with close relationships; (2) ssp. histrio and ssp. aintabensis should be homonym of I. histrio, rather than of its subspecies; (3) I. danfordiaeand I. celikii should be independent species with close relationships; (4) I. pamphylica and I. bakeriana are different species of the subgenus.

Abstract [Persian]

مشخصات آناتومیکی برگ هشت آرایه از جنس زنبق مقایسه و ارتباط بین آنها تعیین گردید. گونه های
Iris danfordiae, Iris celikii, Iris histrioides, Iris pamphylica and Iris histrio ssp. aintabensis
انحصاری ترکیه و گونه های Iris bakeriana, I. celikii, I. histrioides, I. pamphylica, I. histrio ssp. aintabensis and Iris histrio ssp. Histrio دارای پراکندگی محدودی در ترکیه هستند. تفاوت هایی در صفات آناتومیکی گونه ها به خصوص در لایه مزوفیل برگ مشاهده گردید که بر اساس آنها Iris reticulata , Iris histrioides  می بایستی به عنوان گونه های مستقل محسوب شوند. زیر گونه های histrio  و aintabensis می بایستی به عنوان هم نام گونه I. histrio در نظر گرفته شوند. گونه های I. danfordiae و  I. celikii گونه هایی مستقل باخویشاوندی نزدیک هستند و I. pamphylica  و I. bakeriana گونه های متفاوت این زیر جنس هستند.
