The distribution of aquatic plants in Taiwan is different due to the development of the environment. In order to adapt to the environment of different water levels, the common aquatic plants in Taiwan have developed various living habits, which can be roughly divided into submerged plants, floating plants, floating plants, water-standing plants and wet plants. Common submerged plants are goldfish algae and water herbs; floating-leaf plants are water lilies and water chestnuts; floating plants are cloth bag lotus and Manjianghong; water-standing plants are and flowers and duckweed; and wet-type plants are sea taro and wild ginger flowers.

Aquatic plants in Taiwan usually live in small wetlands caused by flat swamps, slow-flowing streams and springs; a few are born in ponds in hilly or alpine areas, but most of the former's habitats overlap with human activities. therefore, it is easy to be disturbed or destroyed by human activities, which displaces the native aquatic plants. Or powerful alien species brought into the habitat by humans, such as Oncomelania hupensis and bougainvillea, also pose a major threat to them. For example, a new species of ─, which was only published in 2002, was originally distributed in the wetlands on the outskirts of Longtan, Taoyuan. It is endemic to Taiwan, but due to the destruction of its habitat by human activities, there is not much left in the wild.
