Morphological Investigation of Genus Ziziphus Mill
ples of Ziziphus plants were collected from the field. A twig of 24 cm which contained both floral and vegetative part was collected from each plant and was pressed immediately in the field to maintain the morphological features such as fruit, flower and leaves of the plant for the analysis. The specimens were identi-fied in the herbarium.

Molecular and Morphological Characterization of Xiphinema
ABSTRACT. A population of Xiphinema chambersi from the root zone around live oak (Quercus virginiana Mill.) trees on Jekyll Island, GA, is described using both morphological and molecular tools and compared with descriptions of type specimens. Initially, because of a few morphological differences, this nematode was thought to represent an undescribed species.

Morphology of Leaf
The xerophytic plants and plants belonging to the Crassulaceae family have thick and succulent leaves that store water in their tissues. The parenchymatous cells of these leaves have large vacuoles filled with hydrophilic colloid. This modification helps the plant to resist desiccation. Leaf Tendrils. Leaf tendrils exist in plants with weak stems.
