The examination of the petioles exhibits new and varied characters such as petiole shape (cross section), vascular bundles (shape, number, arrangement). While the resulted characters from the observation of the stem structure showed less variation. Nineteen qualitative characters with 38 character states resulted from leaf anatomy.

This study aimed to characterize the stem, peduncle, and leaf anatomy of 22 species of Sedum senso lato distributed in Iran. The results showed that the presence of tanniniferous storage cells in stems and leaves, distinct xylem vessels in stems, and the shape of peduncle cross sections, were taxonomically informative evidence, and isolated Phedimus from the other studied taxa of Sedum s.l., whereas hairy leaves and peduncles containing starch storage cells were identified as Prometheum and Hylotelephium respectively.

In our study, cross section of the healthy and Tungro infected leaf sample of rice exhibited wide differences among the cells. The area of vascular bundles was reduced in the Tungro infected rice samples and lower epidermis cells got damaged wherein the area was large in the healthy rice leaf. In case of healthy leaves of rice, the cells were normal in size with properly distributed intercellular spaces and evenly present bundle sheath cells. The xylem and phloem tissues showed no damage in healthy sample. Bundle sheath cells remained undisturbed above the phloem tissues.
