Expanded Information:

Taro, like giant calla lilies, turtlebacks, and anthuriums, are of similar lineage, and all belong to the family of plants of the family Amanita. The fleshy inflorescences of plants in the family Tennantaceae are wrapped in involucral bracts shaped like corollas. The bracts are called "spathes" because they resemble the candlesticks used in temples to worship the Buddha.

The spathe is a flower of the Amanita family, and has a peculiar shape. The spathe also contains a complex and subtle story, especially the pollination story of Amanita phalloides is particularly wonderful. The male and female flowers of the family are hidden in the spathe, and when you open the lower spherical structure of the spathe, you can see the male and female flowers of the family arranged up and down.
