|
| Vallisneria and the submerged forms of Sagittaria have long, ribbon-like, entire leaves. |
| Laceolate, entire leaves on long stems are found in Elodea, Egeria, and the alien Hydrilla. |
| A comparison of the entire leaves of the three genera above can be seen here. |
| Fenestrate leaves can be seen in Aponogeton fenestralis and A. madagascarensis. |
| Examples with dissected leaves are Cabomba caroliniana, Myriophyllum spicatum, and Ceratophyllum demersum. |
| In this Elodea Leaf c.s. note the chloroplasts in the epidermis, the reduction of the lamina to two epidermal layers, and the lack of differentiated xylem and phloem in the vascular bundle. |
| This is the chemical reaction that results in marl production by aquatic hydrophytes. |
| Examine the lacunal systems of various submerged organs and note the reduction of the vascular system: Isoëtes Leaf c.s., Myriophyllum Stem c.s., and Scirpus Stem c.s. |
