Isoetids are aquatic plants or wetland plants named for their superficial similarity to the quillworts, Isoetes. They occur in wetlands and on shorelines with low nutrient availability.[1] Owing to their slow growth rates, they are also often found in areas with low rates of sediment deposition.[2] Many have evergreen leaves, and CAM photosynthesis.[3] Often they are exposed during periods of low water. Common examples include Lobelia dortmanna and Eriocaulon aquaticum.
