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.

Crocus cf. heuffelianus Herb. belongs to the series Verni Mathew and presents one of the most complex and critical taxa within the whole genus Crocus L. Depending on different authors, C. cf. heuffelianus is sometimes split into different taxa (e.g., C. scepusiensis (Rehmer & Wol.) Borbás ex Kulcz., C. vittatus Schloss. & Vuk., nom. illeg.).

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.

Vascular and supporting systems play important roles and are closely related to leaf morphology. To understand and compare vascular and supporting systems in several leaf types in Arecaceae, we studied leaf structure of species in different genera, including Cocos nucifera, Phoenix roebelenii and Calamus tetradactylus.

The main objective of this study is to assess the significance of anatomical characteristics of the leaves. For this purpose, dehydrated specimens were embedded into paraffin and transverse sections were gathered. Furthermore, the leaf surfaces were examined.
