Description
Color enhanced scanning electron micrograph (SEM) of horsetail (Equisetum giganteum), a plant with a long history, that formed much of the vegetation during the carboniferous period. They have existed for about 300 million years and have remained practically unchanged. The outer epidermis is thick and contains silica (blue-gray), making the herb useful for polishing metals (pewterwort). The picture shows the surface of a plant with stomata. Magnification 260x
