Senecio cinsi Türkiye Florası’nda 50 takson ile
temsil edilmektedir (41 tür, 3 alttür ve 6 varyete). 50 taksonun 20’si Türkiye
için endemiktir ve endemizm oranı % 40’dır. Türkiye’de bulunan Senecio cinsine ait Senecio vulgaris L.
subsp. vulgaris,  Senecio
lividus L., Senecio viscosus L.
türlerinde gövde ve yaprak anatomisi ışık mikroskopisi ile aken meyve yapısı
ışık mikroskopisi ve geçirmeli elektron mikroskopisi (TEM) ile incelenip,
morfolojik, anatomik ve histolojik farklılıklar ortaya çıkartılarak cinsin
taksonomik problemlerinin çözümlenmesine katkıda bulunmak amaçlanmıştır.

Genus Senecio (Asteraceae) is represented by 52 taxa in Flora of Turkey (43 species, 3 subspecies and 6 varietes). 20 of these 52 taxa are endemic to Turkey and the endemism ratio is 40%. This study is comprises the species of Senecio vulgaris L. subsp. vulgaris, Senecio lividus L. and Senecio viscosus L. distrubuted in Turkey. Stem and leaf anatomy of the species were
examined by light microscopy, and achene fruit structure was examined by light and transmission electron microscopy. This study aims to identify morphological, anatomical and
histological differences between these species and contribute to the resolution of taxonomic problems of the genus.
