Anatomical characteristics of the vegetative parts of Orchis italica Poiret in Turkey have been<br />
investigated in this study. Orchis italica samples were collected from Ezine (Çanakkale),<br />
Selçuk (�zmir) and Milas (Mu�la) between 2007 and 2009. Permanent microscopic<br />
preparations were made of plant material fixed in field in 70 % alcohol. Cross sections of the<br />
leaves, stem, tuber and root and surface sections of leaves taken by free-hand and stained with<br />
Sartur solution and Safranin. The well-staining sections were photographed on Leica DFC295<br />
color camera type, Leica DM2500 light microscope.<br />
The leaves are anomostomatic and tetrastic, have no trichomes. The cuticle thickness (abaxial<br />
and adaxial), epidermis cell size (abaxial and adaxial) and stomata dimensions and stomata<br />
index were measured. The epidermis are lined parellel by the midrib and surrounded by<br />
cuticle. In cross sections of the lamina, upper epidermis are larger than lower epidermis.<br />
Vascular bundles are collateral and consist of xylem, phloem and sclerenchyma cells. Raphide<br />
are observed in the mesophyll tissue. Midrib has lacunas. Chlorenchyma has been scattered<br />
homogeneous. In cross sections of stem, the epidermis consist of a single layered, flattened,<br />
roundish or ovate cells and surrounded by thin cuticle layer. Parenchyma and chlorenchyma<br />
were observed along cortex. Vascular bundles are collateral type and are surrounded by<br />
sclerencymatic tissue. In cross sections of the tuber, parenchymatic pith cells have starch and<br />
raphide. A single layered epidermis, exodermis, parenchymatic cortex, a single layered<br />
endodermis, periscyle, and vascular bendle have been observed in cross sections of the root.<br />
