    abstract = {<i>Nerium oleander</i> (Apocynaceae) which spread
over a wide area along the Mediterranean coast, is an
important indicator plant of Mediterranean elements. The
objective of the current research was to reveal the altitude
effect of <i>N. oleander</i> in the Middle-West Taurus region
situated in Turkey. In this study, it is statistically
evaluated that the micro morphological and anatomical
changes observed in tissues of the leaves collected at
different altitudes. Leaf structure of <i>N. oleander</i>
demonstrated morphological, epidermal and anatomical
alterations at various elevations. Statistical analysis was
subjected to analysis of covariance (ANCOVA).
According to the Levene test results, it is determined that
the Wmed and Lmed averages of some anatomical parts
such as spongy parenchyma cells, collenchyma and xylem
layers, increase as the altitude escalates. This result has
been supported by the correlative effect of locality and
anatomical parts and it is significantly relating the
measurement of Wmed (p = 0.000<0.05). In micro
morphological studies, trichome density and cavities were
seen in the stomatal crypt chamber, the sizes of the upper
and lower epidermal cells and the structures of anticlinal
walls were examined in the superficial incisions.
Considering the altitudes starting from 3 m up to 898 m,
it is observed that the trichomeson the leaf epidermal
surface were observed to decrease as altitude increases,
while any remarkable difference was not found for the
trichomes located in the stomatal crypt. Notwithstanding,
the crystals in the leaf mesophyll layer were more
concentrated at low altitude (3 m) while abundance
decreased at higher altitudes (898 m).}
