Özet:

 The morphological features and distributions of trichomes on both vegetative and reproductive organs of endemic Ballota macrodonta were examined in this study. The species has limited distrubution in Türkiye and is endemic Iranian Turanian element. In this taxon, different trichome types were seen and these trichomes were divided into two main groups. The first group forms eglandular trichomes, the other group forms glandular trichomes. Two types of eglandular trichomes were obtained on the vegetative and reproductive organs of the taxon: simple unbranched and branched. Stellate type of branched eglandular trichomes were seen more frequently on the lower surface, margins, veins of leaves, corolla, and outer part of calyx, while long unicellular, bicellular, tricellular and multicellular types of simple unbranched eglandular trichomes were seen more frequently on all the organs of this taxon. Glandular trichomes were categorized as capitate with different stalk lengths and onetwo head cells and peltate with foureight secretory cells. According to number of stalk cells, capitate trichomes were grouped into as unicellular, bicellular, tricellular and multicellular trichomes. The capitate ones were seen nearly on all organs of B. macrodonta. Peltate trichomes were rarely found on the stem, upper surface of leaf and corolla, while these trichomes were densely found on the surface of the calyx. It was emphasized that both simple unbranched and stellate eglandular trichomes could be used as valuable characters in the classification of this species.

 Bu çalışmada, endemik Ballota macrodontanın hem vejetatif hem de üreme organları üzerindeki tüylerin morfolojik özellikleri ve dağılımları incelendi. Tür, Türkiye de limitli yayılışa sahiptir ve endemik Iran-Turan elementidir. Bu taksonda, farklı tüy tipleri görüldü ve bu tüyler iki ana gruba ayrıldı. Birinci grup örtü tüylerini oluşturur, diğer grup salgı tüylerini oluşturmaktadır. Taksonun vejetatif ve üreme organları üzerinde örtü tüylerinin iki tipi bulundu: basit dallanmamış ve dallanmış. Basit dallanmamış örtü tüylerinin uzun bir hücreli, iki hücreli, üç hücreli ve çok hücreli tipleri bu taksonun bütün organları üzerinde daha sık görülürken, dallanmış örtü tüylerin yıldızsı tipine yaprakların alt yüzeyinde, yaprakların damarları ve kenarlarında, korolla ve kaliksin dış yüzeyinde daha sık görüldü. Salgı tüyleri farklı sap uzunluklarına ve bir-iki baş hücreye sahip kapitat ve dört-sekiz salgı hücresine sahip peltat olarak kategorize edildi. Sap hücre sayılarına göre, kapitat tüyler bir hücreli, iki hücreli, üç hücreli ve çok hücreli olarak gruplandırıldı. Kapitat olanlar B. macrodontanın hemen hemen bütün organlarında görüldü. Peltat tüyler nadir gövdede, yaprağın üst yüzeyinde ve korolla da nadir olarak bulunurken, bu tüyler kaliks yüzeyinde yoğun olarak bulundu. Bu türün sınıflandırılmasında hem basit dallanmamış hem de yıldız şeklindeki örtü tüylerinin değerli karakterler olarak kullanılabileceği vurgulandı.
