ANATOMICAL ASPECTS OF CYPERUS ALTENIFOLIUS ROTTB.

Abstract

The paper presents histo-anatomical aspects of the vegetative organs (adventitious root, rhizome, scape and leaf) of a perennial herb, native to the swampy regions of Japan and Taiwan namely Cyperus alternifolius Rottb.It belongs to Cyperaceae family. In our country the plant is known as an ornamental plant. The material fixation and processing was done according to the usual protocol of the vegetal morphology and anatomy Laboratory belonging to the Natural Sciences Department of the our faculty. The adventitious root has a primary monocot structure with a developed aerenchymcreated by lyses of cell walls. The rhizome vascular system consists of amphivasalcollateral bundles to the center and peripheral few bundles.The scape is well-developed with epidermis, hypodermis and a number of air chambers. The leaf mesophyll ishomogenous, represented spongy tissue. In the mesophyll are embedded few poor developed vascular bundles.The aim of this study is bring some new characteristics to complete the anatomical structure of adventitious root, rhizome, scape and leaf of this species.
