- Abstract
This paper presents the histo-anatomical characteristics of the stem, nodal branches and leaves of three Equisetum species, Equisetum pratense, Equisetum telmateia and Equisetum sylvaticum, commonly known as "horsetail". This study was elaborated using color photographs acquired from optical microscopy (OM) and scanning electron microscopy (SEM) observations. Using OM investigations, several structures have been evidenced: the epidermal wall cells, the outer cortex made of different types of tissues and the central cylinder organized into two regions: an external layer that enclosed vascular bundles and an internal layer represented by a large air cavity. The images achieved by SEM showed some differential characteristics concerning the trichomes and stomata but also the manner in which granules of silicon dioxide are spread throughout the surfaces of Equisetum species. These results could be used as a criterion for species differentiation as they have taxonomic value in the Equisetum family.
