Eriocaulaceae
The Eriocaulaceae are a family of monocotyledonous flowering plants in the order Poales, commonly known as the pipewort family. The family is large, with about 1207 known species described in seven genera. They are widely distributed, with the centers of diversity for the group occurring in tropical regions, particularly the Americas. Very few species extend to temperate regions, with only 16 species in the United States, mostly in the southern states from California to Florida, only two species in Canada, and only one species (''Eriocaulon aquaticum'') in Europe. They tend to be associated with wet soils, many growing in shallow water. This is also reported from the southern part of India and the regions of Western Ghats hot spots. The species are mostly herbaceous perennial plants, though some are annual plants; they resemble plants in the related families Cyperaceae (sedges) and Juncaceae (rushes), and like them, have rather small, wind-pollinated flowers grouped together in ca ...

Tide
Tides are the rise and fall of sea levels caused by the combined effects of the gravity, gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or "tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the #Phase and amplitude, phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see ''#Timing, Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal cycle, diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sagittaria Latifolia
''Sagittaria latifolia'' is a plant found in shallow wetlands and is sometimes known as broadleaf arrowhead, duck-potato, Indian potato, katniss, or wapato. This plant produces edible tubers that have traditionally been extensively used by Native Americans. Description ''Sagittaria latifolia'' is a variably sized perennial, ranging from in length and growing in colonies that can cover large areas of ground. The roots are white and thin, with the green and white mother plant producing white tubers ranging from long and deep, covered with a purplish skin. The plant produces rosettes of leaves and an inflorescence on a long rigid scape. The leaves are extremely variable, from in length and thin to wedge-shaped like those of '' S. cuneata''. Spongy and solid, the leaves have parallel venation meeting in the middle and the extremities. The inflorescence is a raceme about above water and composed of white flowers whorled by threes, blooming from July to September. The ...

Sagittaria Subulata
''Sagittaria subulata'', the awl-leaf arrowhead, narrow-leaved arrowhead or dwarf sagittaria, is an aquatic plant species. Description It is a perennial herb up to tall. The leaves are submersed or floating, narrowly linear to ovate, not lobed. The inflorescence floats on the surface of the water. Distribution and habitat It is native to the Colombia, Venezuela, and every US state along the coast from Massachusetts to Louisiana.

It is also recorded as a non-native on the Azores, and on the Island of Java in Indonesia. It grows primarily in shallow brackish water along the seacoast, in marshes, estuaries, etc. Conservation It is listed as special concern in Connecticut, as endangered in Massachusetts, as rare in Pennsylvania, and as historical in Rhode Island.

Isoetes Riparia
''Isoetes riparia'', the shore quillwort, is a species of plant in the family Isoetaceae. It can be found in rivers, creeks, and tidal mud flats in southern Quebec and southeastern Ontario, south to eastern New York. It has 5 to 35 long, erect bright green to yellow-green leaves, which are 6 to 35 centimeters long. The velum covers one fourth of the sporangium, which can be 7 millimeters long and 4 millimeters wide. The elongated ligule can grow to be 3 millimeters long. The spherical megaspores are 430 to 680 micrometers in diameter with closely set ridges. The kidney-shaped microspores are 24-35 micrometers long, and usually have spine-tipped tubercules. The megaspores can sometimes come to resemble that of either '' I. echinospora'', if the megaspores become eroded and bear projections that could resemble spines, or '' I. macrospora'', if the broken ridges take a certain shape.
