Zostera
''Zostera'' is a small genus of widely distributed seagrasses, commonly called marine eelgrass, or simply seagrass or eelgrass. The genus ''Zostera'' contains 15 species. Ecology '' Zostera marina'' is found on sandy substrates or in estuaries, usually submerged or partially floating. Most ''Zostera'' are perennial. They have long, bright green, ribbon-like leaves, the width of which are about . Short stems grow up from extensive, white branching rhizomes. The flowers are enclosed in the sheaths of the leaf bases; the fruits are bladdery and can float. ''Zostera'' beds are important for sediment deposition, substrate stabilization, as substrate for epiphytic algae and micro-invertebrates, and as nursery grounds for many species of economically important fish and shellfish. ''Zostera'' often forms beds in bay mud in the estuarine setting. It is an important food for brant geese and wigeons, and even (occasionally) caterpillars of the grass moth '' Dolicharthria punctalis''. ...

''Vallisneria'' (named in honor of Antonio Vallisneri) is a genus of freshwater aquatic plant, commonly called eelgrass, tape grass or vallis. The genus is widely distributed in tropical and subtropical regions of Asia, Africa, Australia, Europe, and North America. ''Vallisneria'' is a submerged plant that spreads by Vegetative reproduction, runners and sometimes forms tall underwater meadows. Leaf, Leaves arise in clusters from their roots. The leaves have rounded tips, and definite raised veins. Single white female flowers grow to the water surface on very long stalks. Male flowers grow on short stalks, become detached, and float to the surface. It is dioecious, with male and female flowers on separate plants. The fruit is a banana-like capsule having many tiny seeds. Sometimes it is confused with the superficially similar ''Sagittaria'' when grown submerged. This plant should not be confused with ''Zostera'' species, marine seagrasses that are usually also given the common n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
