چکیده مقاله:
The genus Cyperus with five subgenus and ۲۹ species, is the second largest genus of Cyperaceae family in flora of Iran. In this research, stem and leaf anatomy of ۱۰ species belonging to subgenus Cyperus is investigated. The stems in transverse section of all examined species were triangular except for C. bulbosus which was subterete to polygonal. The ground tissue was spongy with numerous and large air cavities in all studied taxa, while in C. bulbosus was spongy with small air cavities or not. In C. glomeratus and C. malaccensis, ground tissue is net-like with numerous air cavities. Leaf anatomy of all studied species showed radiate chlorenchyma and ۲-layered bundle sheaths (outer fibrous and inner parenchymatous). Air cavities are composed of stellate cells except for C. bulbosus.
