Anatomical features of four Pilosella Vaill. taxa (P. officinarumVaill., P. piloselloides (Vill.) Sojak subsp. bauhini (Schult.) S. Bräut. & Greuter, P.× hypeurya (Peter) Sojak,P. densiflora (Tausch) Sojak) collected from Black Sea Region of Turkeywere investigated. Anatomical studies include transverse sections of root, stemand leaf with their illustrations. Although the anatomical properties aresimilar to the typical anatomy of dicotyledons, some differences were observedamong them. While root anatomy of P. officinarum, P. piloselloides subsp. bauhini and P. densiflora consist of a single layer exodermis, there is 2-3 layer exodermis in the natural hybrid P. × hypeurya. Additionaly theroot pith of this hybrid taxacompletely composed of schlerenchyma cells in contrast to other investigatedtaxa. The stem anatomy of the investigated taxa is similar to each other exceptthe number of the tracheidal elements. The numbers of the stomata per µm2 disticltly differ in P. piloselloides subsp. bauhini from the rest examinedtaxa., Anatomical features of4 Pilosella Vaill. species (P. officinarum Vaill., P. piloselloides (Vill.) Sojak, P. hypeurya (Peter) Sojak, P.densiflora (Tausch) Sojak) collected from Black Sea Region of Turkey wereinvestigated. Anatomical studies include transverse sections of root, stem andleaf with their illustrations. Although the anatomical properties are similarto the typical anatomy of dicotyledons, some differences were observed amongthem. While root anatomy of P.officinarum, P. piloselloides andP. densiflora consist of a singlelayer exodermis, it consist of 2-3 layer in P.hypeurya Additionaly the root pithof P. hypeurya is completely composedof schleranchymatic cells in contrast to other investigated species. The stemanatomy of the investigated species is similar to each other except the numberof the tracheidal elements. The numbers of the stomata per µm2 disticltly differ in P. piloselloides,from the rest examined species.
