When the waters rise as the annual floods in the Kafue Flats commence, upon regular occasion large chucks of Vossia and Echinochloa stems detach, and these slowly dying clumps of grass become wind-blown floating mats in the swamps, which host their own unique ecosystem, dominated by the sedge Pycreus mundii, and further supporting the sedges ...

Ophiopogon planiscapus is a species of flowering plant in the family Asparagaceae. It is a small evergreen perennial growing to 20 cm (8 in) tall by 30 cm (12 in)wide. [1] It grows from short rhizomes, and bears tufts of grasslike leaves, from which purple or white flowers emerge in racemes held on short stems above the leaves.
The fountainplant is an evergreen, sod-forming perennial plant. The leaves are linear, 20–40 cm long. The flowers are white through pale lilac, borne in a short raceme on a 5- to 1-cm stem. The fruit is a blue berry, 5 mm in diameter. [2] Underground, this species has large stolons with tuberous roots. [3]
The grass can hinder water circulation and drainage or block boating channels. Meadows of S. alterniflorus can crowd out native species, reducing biodiversity and altering the environment; as a result of S. alterniflorus 's growth, invertebrates that live in mud flats disappear as their habitat is overgrown, and in turn, food sources shrink for ...
Freshwater ecosystem. Freshwater ecosystems are a subset of Earth's aquatic ecosystems that include the biological communities inhabiting freshwater waterbodies such as lakes, ponds, rivers, streams, springs, bogs, and wetlands. [1] They can be contrasted with marine ecosystems, which have a much higher salinity. Freshwater habitats can be ...
Freshwater marshes are highly productive and therefore can support a large biodiversity of vegetation. Vegetation is a key component in determining the structure of a freshwater marsh. [7] In a freshwater marsh, there are emergent plants, floating plants, floating leaved and submerged. [8] The primary plant in freshwater marshes are emergent ...
This species of grass has hard, sturdy, hollow stems that may reach 3 m (9.8 ft) in height. [4] They grow from a network of woody rhizomes and tough roots that form a sod. The roots penetrate over 3 m (9.8 ft) into the soil. [2] The leaves have sharp, serrated edges. [5] The panicle may be up to 50 cm (20 in) long and may have many branches.
