Morphological, anatomical, palynological and ecological studies on mullein (Verbascum L.) taxa in Tekirdağ

Verbascum L. is one of Turkey's largest genus, in terms of the number of taxa. It is represented by 360 species worldwide. After Flora of Turkey and the East Aegaen Islands published, Verbascum is represented by 255 species (413 taxa) and the 106 hybrids with newly described taxa in Turkey. 192 of the Verbascum taxa (198 with hybrids) are endemic to Turkey. Studies on the genus Verbascum are mostly based on taxa that are close to each other in terms of regional, endemic or taxonomic. In this thesis, the distribution of Verbascum taxa in Tekirdağ was determined and morphological, anatomical, palynological and ecological studies were carried out on these taxa. Also, IUCN threat categories have been determined. It is known that 10 taxa spread in Tekirdağ before this thesis. However, this number increased to 17 taxa with this thesis. The distribution of Verbascum bombyciferum, V. thapsus and V. vacillans in Thrace region and in Tekirdag province, V. banaticum, V. blattaria, V. densiflorum and V. ovalifolium subsp. thracicum in Tekirdağ province has been demonstrated with this thesis for the first time. Although the distribution and habitat information of V. orientale subsp. orientale and V. mucronatum taxons given in the literature were utilized, existing distribution in Tekirdağ province could not be determined during the field studies.
