Echinodorus palaefolius has round leaves with a horizontal leaf base. Under water the leaves are narrower and longer. The next leaves will then become shorter and the plant will remain under water. Common as aquarium plants, they grow even larger as emersed pond plants.
Sagittaria sagittifolia 'Flore Pleno' is also known with an invalid name: S. latifolia 'Flore Pleno'. This double flowering arrowhead is very beautiful and hard to get even in Malaysia. The plants produce two to three leaves per week in tropical climate so it gets invasive. The rhizome of Sagittaria sagittifolia are used respectively by the North American Indians and the Chinese as starchy foods, as are some other species.
