The morphological anatomy of the vegetative organs of the Woodwardia unigemmata was studied by the method of segregation and paraffin sectioning. It indicated that: W. unigemmata leaves were heterologous leaves. The upper and lower epidermis cells were irregular, and only the lower epidermis had stomatal distribution. There are 2 to 6 vascular bundles in petiole, only 2 larger vascular bundles from petiole base up to leaf axis. Rhizome have multiple vascular bundles scattered among the parenchyma cells, and rich starch grains in parenchyma cells. Cortex takes up a large proportion in the transverse structure of roots, and xylem develops in an exogenous manner. The development process of W. unigemmata bulbil can be divided into three stages: the formation stage of bulbil primordium, the differentiation stage and the maturation stage of bulbil primordium.
