The leaf anatomy of some Erica taxa native to Turkey

The leaves are channelled beneath or strongly revolute. The long, simple, and unicellular eglandular trichomes are located along the channel part of the lower surface of leaves. There are simple, unicellular, and usually short eglandular trichomes on the surface of the upper epidermis. | A. GÜVENÇ, G. KENDİR Research Article Turk J Bot 36 (2012): 253-262 © TÜBİTAK doi: The leaf anatomy of some Erica taxa native to Turkey Ayşegül GÜVENÇ*, Gülsen KENDİR Department of Pharmaceutical Botany, Faculty of Pharmacy, Ankara University, 06100 Tandoğan, Ankara - TURKEY Received: Accepted: Abstract: There are 5 taxa of Erica L. growing in Turkey, 1 of which is endemic. These taxa are Erica arborea, E. manipuliflora, E. bocquetii, E. sicula subsp. libanotica and E. spiculifolia. In this study, microscopic characteristics of the leaves of 4 taxa native to Turkey are reported. Microscopic views of the transverse and surface sections of the leaves of each species were photographed and are described in detail. The leaves are channelled beneath or strongly revolute. The long, simple, and unicellular eglandular trichomes are located along the channel part of the lower surface of leaves. There are simple, unicellular, and usually short eglandular trichomes on the surface of the upper epidermis. Key words: Erica, leaf, anatomy, Ericaceae Türkiye’nin bazı doğal Erica taksonlarının yaprak anatomisi Özet: Türkiye’de doğal olarak yetişen biri endemik 5 Erica L. taksonu vardır. Bu taksonlar, Erica arborea, E. manipuliflora, E. bocquetii, E. sicula subsp. libanotica ve E. spiculifolia’dır. Bu çalışmada, Türkiye’de doğal olarak yetişen bu taksonların 4 tanesinin yaprak anatomik özellikleri incelenmiştir. Her bir türün yapraklarından alınan enine ve yüzeyel kesitlerin mikroskobik özellikleri ayrıntılı olarak tanımlanmış ve fotoğraflanmıştır. Yapraklar alt yüzde kanallı ve kuvvetli bir şekilde kıvrıktır. Basit, uzun ve tek hücreli örtü tüyleri, yaprakların alt yüzünde bu kanallar boyunca yer almaktadır. Üst epidermada bir hücreli basit ve genellikle kısa örtü tüyleri vardır. Anahtar sözcükler: Erica, yaprak, anatomi, Ericaceae Introduction The genus Erica L. (Ericaceae) is represented by more than 700 species throughout the world .
