Anatomical features of four Pilosella Vaill. taxa (P. officinarum
Vaill., P. piloselloides (Vill.) Sojak subsp. bauhini (Schult.) S. Bräut. & Greuter, P.× hypeurya (Peter) Sojak,
P. densiflora (Tausch) Sojak) collected from Black Sea Region of Turkey
were investigated. Anatomical studies include transverse sections of root, stem
and leaf with their illustrations. Although the anatomical properties are
similar to the typical anatomy of dicotyledons, some differences were observed
among 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 the
root pith of this hybrid taxa
completely composed of schlerenchyma cells in contrast to other investigated
taxa. The stem anatomy of the investigated taxa is similar to each other except
the number of the tracheidal elements. The numbers of the stomata per µm2 disticltly differ in P. piloselloides subsp. bauhini from the rest examined
taxa.
