Common name: Monocots

Liliopsida, commonly known as monocots, are a class of flowering plants characterized by a single embryonic leaf or cotyledon. This class includes a diverse range of plants such as grasses, lilies, orchids, and palms. In the reefkeeping hobby, seagrasses like those from the genus Halophila and Thalassia are of particular interest. These seagrasses can be kept in refugiums or main displays, providing habitat for small invertebrates and helping with nutrient export.
