The leaves are pinnate compound leaves, and the tips are sharp and painful to the touch. Although it is a seed plant, the presence of sperm has been confirmed along with ginkgo.

Fruit of cycad. The size is about 3-4 cm. Although cycad nuts and stems contain a large amount of starch, they are toxic and often die when eaten. However, it could be detoxified by sufficient treatment such as exposure to water, and it was a valuable food for famine.
