The term for a specialized form of plant life in a particular environment is "endemic species." Endemic species are those that are native to a specific geographic area and are not found naturally anywhere else. This uniqueness occurs due to factors like geographical isolation, ecological conditions, and evolutionary processes. Endemic species are often particularly vulnerable to extinction due to habitat loss or changes in environmental conditions since their survival is closely tied to their specific habitats. Examples include many types of flora and fauna that thrive in isolated ecosystems, such as the Galápagos Islands or Madagascar.
