TI  - Leaf anatomy of Quercus macranthera subsp. syspirensis (K.Koch) Menitsky
AB  - The genus Quercus L. (Fagaceae) is represented by 461 species worldwide. Its distribution ranges from the 
temperate northern hemisphere to Malaysia and Colombia. Quercus bark is rich in tannins and is used as an astringent. 
Quercus macranthera subsp. syspirensis (K.Koch) Menitsky is endemic to Turkey and is known as "ispir meşesi". The 
plant is a small deciduous tree up to 7 m tall. Leaves obovate with 5-9 short lobes, stipules filiform, primary veins 6-10 
and petiole 5-20 mm.
The plant material was collected from Kastamonu-Araç (Turkey). A voucher specimen was deposited in the 
Ankara University Faculty of Pharmacy Herbarium (AEF). The samples for anatomical studies were protected in 70% 
alcohol. The transverse and surface sections were cut by hand with razor blade into microscopic preparat form. The 
Sartur solution was used in microscopic examinations. Leica DM 4000B microscope was used for anatomical analysis 
and micro photographing. 
According to the results of the anatomical study, the leaf is bifacial. Numerous stellate hairs are found on the 
upper and lower epidermis. Stomata are located only on the lower epidermis. The leaf and petiole contain solitary 
crystals. The petiole is characterized by a numerous stellate hairs. The sclerenchymatous tissue surrounds the vascular
bundles in the form of a ring.
