Eleocharis is a virtually cosmopolitan genus of 250 or more species of flowering plants in the sedge family, Cyperaceae. The name is derived from the Greek words ἕλειος (heleios), meaning "marsh dweller," and χάρις (charis), meaning "grace." Members of the genus are known commonly as spikerushes or spikesedges. The genus has a geographically cosmopolitan distribution, with centers of diversity in the Amazon Rainforest and adjacent eastern slopes of the South American Andes, northern Australia, eastern North America, California, Southern Africa, and subtropical Asia. The vast majority of Eleocharis species grow in aquatic or mesic habitats from sea level to higher than 5,000 meters in elevation.
Rhynchospora alba, the white beak-sedge, is a plant in the sedge family, Cyperaceae. It is a tufted herbaceous perennial around 50 cm tall, with white inflorescences that flower in August. The fruit of the sedge is a small achene with a characteristic beak-like cap. It is dispersed by wind or falls by gravity, leading to individuals existing in tight clumps. The species favours wet, acidic and nutrient poor soils, thriving in Sphagnum-dominated bogs, but also peaty grasslands. As such, it is often used as a positive indicator for bog and mire ecosystem health.

The spongy, compressible stem is a few millimeters wide and sharply four-angled. The inflorescence is a single spikelet 1.5 to 7.5 centimeters long which is made up of several flowers covered in light brown bracts.
Eleocharis rostellata is a species of spikesedge known by the common name beaked spikerush. It is widespread across North America, with isolated populations in Argentina.
Eleocharis tuberculosa, the cone-cup spikerush, is a plant species native to the United States and Canada. It has been reported from every state on the Gulf and Atlantic coasts from Maine to Texas, plus Kentucky, Tennessee, Arkansas and Nova Scotia. It is found in wet soil in meadows, woodlands, lake shores and river banks.

It inhabits in water, usually in shallow or deep lakes and ponds. The plant has slender stem with many branches, the leaves float in the water and flowers are usually emergent over the water surface. Fruiting occurs in fall. The most occurrences of plant appear in April and frequency of occurrences is increasing the last years
