Abstract

In this study, morphological and
anatomical features of two morphologically similar species (Iris peshmeniana Güner & T. Hall. and
Iris aucheri (Baker) Sealy) within
the Scorpiris Spach subgenus (Juno iris) of the genus Iris
L. were determined and similarities and differences between the two species
were discussed. Iris peshmeniana is endemic to Turkey and its spreading area is
protected because of exctinction threat. Iris
aucheri is not endemic to Turkey and it has a limited distribution in the
country. The cross-sections
from root, scape and leaves and surface-sections from leaves of species were
taken. Anatomical and morphological evaluations of the collected and obtained
samples revealed differences in plant size, leaf number, width and length, periant tube
length, fall length, standard structure, capsule length and width, bract and
bracteole structure, length of style branches and testa structure of seeds and
in the number of exoderma and cortex layers, margin structure of cortex
paranchyma cells, structure of the root center
cylinder, xylem strand number,
status micropapillae in lower epiderma, layer number of palisade and spongy
parenchyma and status of sclerenchyma cap. Although there were some differences
in morphological and anatomical features, based on similar anatomical and
morphological features revealed in the present study, it has been suggested
that I. peshmeniana may be a
subspecies of I. aucheri.
