Abstract

Iberis taxa natively found in Turkey are
represented by 8 species and are annual and/or perennial herbs or subshrubs. In
this study we provide a detailed anatomical description of Turkish Iberis taxa for the first time and try
to solve the complexity of taxonomical uncertainties of the genus. Root, stem
and leaf anatomies are investigated and stomatal index of Iberis is indicated. Our results provided valuable evidence on
doubtful circumstance of species in this genus. I. attica is the only species that has winged stem structure and
branched trichomes. I. carica, one of
the endemics, is the only species with its continuous vascular cambium in stem
that forms a vascular bundle circle. I.
sempervirens is the only species without indumentum which has also a
subshrub habit. I. odorata is the
only annual species. There are two types of leaf anatomy as bilateral and
isolateral. Iberis taxa found in
Turkey are amphistomatic. Myrosin cells that are the characteristic of the order Brassicales are observed in all
examined species. Anatomical results support that I. attica and I. spruneri
are two separate taxa instead of as combined I. carnosa.
