Avicennia is a genus of flowering plants in the family Acanthaceae, commonly known as mangroves. These trees and shrubs are typically found in coastal intertidal zones, where they thrive in saline environments. They play a crucial role in coastal ecosystems by stabilizing shorelines and providing habitat for various marine and terrestrial species. The most well-known species within Avicennia include Avicennia marina and Avicennia germinans. These plants are characterized by their unique adaptations, such as specialized roots that can filter salt from seawater. Avicennia mangroves are vital for protecting coastlines from erosion and serve as important nurseries for fish and other wildlife.
