[4] [5] This pod, like all legumes, is a single carpel, the largest carpel of any known plant. Inside the pods are ten to fifteen seeds, each of which have a diameter of 6 cm (2.4 in) and a thickness of 2 cm (0.79 in). [6] The seeds contain a hollow cavity, which gives them buoyancy.
Seagrasses evolved from terrestrial plants which recolonised the ocean 70 to 100 million years ago. The name seagrass stems from the many species with long and narrow leaves , which grow by rhizome extension and often spread across large " meadows " resembling grassland ; many species superficially resemble terrestrial grasses of the family ...
Uniola paniculata, also known as sea oats, seaside oats, araña, and arroz de costa, [1] is a tall subtropical grass that is an important component of coastal sand dune and beach plant communities in the southeastern United States, eastern Mexico and some Caribbean islands. Its large seed heads that turn golden brown in late summer give the ...
Seagrasses are flowering plants (angiosperms) which grow in marine environments. They evolved from terrestrial plants which migrated back into the ocean about 75 to 100 million years ago. [ 1 ] [ 2 ] In the present day they occupy the sea bottom in shallow and sheltered coastal waters anchored in sand or mud bottoms.
Holodiscus discolor is a fast-growing deciduous shrub usually from to 1.2–1.5 metres (4–5 feet) in width, and up to 2.1 m (7 ft) tall. Its alternate leaves are small, 5–9 centimetres (2– 3 + 1 ⁄ 2 inches) long and 4–7 cm (1 + 1 ⁄ 2 –3 in) broad, lobed, juicy green when new. [6]
Most are produced by tropical trees, and they can be found on distant beaches after drifting thousands of miles through ocean currents. This method of propagation has helped many species of plant such as the coconut colonize and establish themselves on previously barren islands. Consequently, drift seeds and fruits are of interest to scientists ...

It cannot grow in fresh water but some growth is possible at a salinity of 10 parts per thousand. The plant's preferred salinity range is 25 to 38.5 parts per thousand with a temperature range of 20 to 30 °C (68 to 86 °F). It is found from the low-tide mark down to depths of 30 metres (98 ft), depending on water clarity.
