Plant Parts
This plant, known scientifically as Dryopteris crassirhizoma, is characterized by its distinct morphological structures, most notably its thick and fleshy rhizome. This underground rhizome serves as a vital storage organ for the fern, providing the necessary nutrients and stability for the plant to thrive in its habitat. From this central rhizome, the upright stems emerge, supporting the lush, green fronds that define its appearance. Together, the robust rhizome and the developing stems form the structural foundation that allows the plant to grow and propagate effectively.- Total parts
