چکیده مقاله:
Convolvulus L with different habitats distributed widely in southern parts of Iran. In general, the plant surface is covered by various random types of indumentum. To study the indumentum and using them for systematic purposes, after collecting plants from natural habitats, different hairy parts of the plant s surface (leaf, stem, calyx, and ovary) were first examined by optical microscope and the electron microscope. The results showed that indumentum in this genus is placed in the group of Straight erect –appressed (sericeous. pubescent, pilose and tomentose), dense and flexuous groups. Based on these results, indumentum is one of the significant traits in the classification of this species, however, this character is not significant in species rank, but it is useful to form three groups and four subgroups in this genus
