Abstract
Zygophyllum spp. are xerophytes and high salinity-tolerant plants. Their high alkaloid contents give them an important value. The genus is represented in U.A.E. by 3 species. The classification of species depends on the variable morphological characters that are not sufficient for a convential separation. This gives an importance to micromorphology as a diagnostic feature. This investigation deals with internal structure in addition to macromorphology of these taxa. The results revealed that anatomical features of leaves (shape in cross section, orientation of storage cells and the midvein characters) and stems in different stages of growth (epidermal cells, cortical tissues and the mode of secondary growth) are systematically significant factors in addition to macromorphology (height of the plant, length and composition of the leaf, and ovary shape) in constructing a separation key. Photographs representing these attributes are presented.
