Morphological and Anatomical Comparison of two species of Equisetum plant in different areas of the Syrian coast

Abstract

The study confirmed that there are two species of Equisetum in different areas of the Syrian coast, namely E.arvense  (Ain Allaban-fidreh) and E.telmatia (Qemem- Al-Khawabi river), which have economic and medical value because they contain chemical compounds that have proven effective against different chains of bacteria and fungi, and treatment of some diseases.

The morphology was determined according to the general shape (plant length, color), stem (length, thickness, central cavity volume of the cross section) leaves, cones (dimensions and their place) and Classification based on taxonomic references. In addition making the colored microtome sections of the stem – cone.

the fertile stems appears in the spring before the sterile stems in both species with differences in the concentration of silicic material on the walls of epidermal cells, which appear at the top cones containing sporocytes containing spores.
