TAILIEUCHUNG - Morphological and anatomical studies of annual taxa of Sideritis L. (Lamiaceae), with notes on chorology in Turkey

This study was undertaken to investigate the morphological and anatomical properties of 5 annual taxa of Sideritis. Full descriptions and illustrations of these taxa are given, along with some additional information regarding their ecology and phytogeography. The anatomy of the leaf blade, midrib, and stem of the taxa are described and illustrated. | Research Article Turk J Bot 34 (2010) 83-104 © TÜBİTAK doi: Morphological and anatomical studies of annual taxa of Sideritis L.

(Lamiaceae) includes approximately 150 species of annual and perennial plants distributed mainly in the Mediterranean region. In Turkey, 44 species (55 taxa) are native. Three of these species (5 taxa) are annual and these taxa are included in Burgsdorfia and Hesiodia sections. This study was undertaken to investigate the morphological and anatomical properties of 5 annual taxa of Sideritis. Full descriptions and illustrations of these taxa are given, along with some additional information regarding their ecology and phytogeography. The anatomy of the leaf blade, midrib, and stem of the taxa are described and illustrated. Key words: Sideritis, morphology, anatomy, Labiatae Türkiye’deki bir yıllık Sideritis L.

(Lamiaceae) başlıca Akdeniz bölgesinde yayılım gösteren, bir ve çok yıllık yaklaşık 150 türe sahip bir cinstir. Türkiye’de 44 tür (55 takson) doğal olarak yetişir. Bu türlerden 3’ü (5 takson) bir yıllıktır ve bu taksonlar Burgsdorfia ve Hesiodia seksiyonlarında yer alır. Bu çalışmada Sideritis’in bir yıllık 5 taksonunun morfolojik ve anatomik özellikleri incelenmiştir. Bu taksonların ayrıntılı tanımları ve şekilleri verilmiştir. Ayrıca, ekolojik ve fitocoğrafik bilgilerine de yer verilmiştir. Türaltı taksonlarla birlikte türlerin yaprak ve gövde anatomileri tanımlanmış ve resimlenmiştir.
