The root anatomy of Cycas guizhouensis has been investigated. The result demonstrated that the roots may be
divided into three types, normal, coralline and fleshy ones, according to their morphology and anatomy. The phellogen
of normal and fleshy roots were derived from the first and second parenchyma cel-l layers of epidermis inside, whereas that
of coralline root came from the second and third cortical layer cells below epidermis.
