Alternanthera is a genus of flowering plants in the family Amaranthaceae. It is a widespread genus with most species occurring in the tropical Americas, and others in Asia, Africa, and Australia. Plants of the genus may be known generally as joyweeds, or Joseph's coat. Several species are notorious noxious weeds.
Hydrilla (waterthyme) is a genus of aquatic plant, usually treated as containing just one species, Hydrilla verticillata, though some botanists divide it into several species. It is native to the cool and warm waters of the Old World in Asia, Africa and Australia, with a sparse, scattered distribution; in Australia from Northern Territory, Queensland, and New South Wales.
A number of introduced species, some of which have become invasive species, have been added to New Zealand's native flora and fauna. Both deliberate and accidental introductions have been made from the time of the first human settlement, with several waves of Polynesian people at some time before the year 1300, followed by Europeans after 1769.
Caulerpa taxifolia is a species of green seaweed, an alga of the genus Caulerpa, native to tropical waters of the Pacific Ocean, Indian Ocean, and Caribbean Sea. The species name taxifolia arises from the resemblance of its leaf-like fronds to those of the yew (Taxus).
Nymphoides, or floatingheart, is a genus of aquatic flowering plants in the family Menyanthaceae. The genus name refers to their resemblance to the water lily Nymphaea. Nymphoides are aquatic plants with submerged roots and floating leaves that hold the small flowers above the water surface. Flowers are sympetalous, most often divided into five lobes (petals). The petals are either yellow or white, and may be adorned with lateral wings or covered in small hairs. The inflorescence consists of either an umbellate cluster of flowers or a lax raceme, with internodes occurring between generally paired flowers.
Miconia crenata, commonly called soapbush, clidemia or Koster's curse, is a perennial shrub. It is an invasive plant species in many tropical regions of the world, causing serious damage.
Limnophila sessiliflora, known as dwarf ambulia, ambulis, and Asian marshweed is a flowering plant in the family Plantaginaceae, mostly found in southeast Asia.
In fishkeeping, a refugium is an appendage to a marine, brackish, or freshwater fish tank that shares the same water supply. It is a separate sump, connected to the main show tank. It is a "refugium" in the sense that it permits organisms to be maintained that would not survive in the main system, whether food animals, anaerobic denitrifying bacteria, or photosynthesizers. For some applications water flow is limited in order to protect plants or animals that require slow flow. The refugium light cycle can be operated opposite to the main tank, in order to keep total system pH more stable (due to the uptake of acid-forming CO2 by photosynthesis occurring in the refugium during its "daylight" hours). One volume guideline for a refugium is 1:10 main tank volume.
Lantana camara is a species of flowering plant in the verbena family (Verbenaceae), native to the American tropics. It is a very adaptable species, which can inhabit a wide variety of ecosystems; once it has been introduced into a habitat it spreads rapidly; between 45ºN and 45ºS and less than 1,400 metres in altitude.
Ceratophyllum demersum, commonly known as hornwort, rigid hornwort, coontail, or coon's tail, is a species of flowering plant in the genus Ceratophyllum. It is a submerged, free-floating aquatic plant, with a cosmopolitan distribution, native to all continents except Antarctica. It is a harmful weed introduced in New Zealand. It is also a popular aquarium plant. Its genome has been sequenced to study angiosperm evolution.
Cabomba caroliniana, commonly known as Carolina fanwort and various other names, is an aquatic perennial herbaceous plant native to North and South America. Having been a popular aquarium plant, it has been exported around the world, and has become an invasive species in Europe and Australia.
Cabomba furcata is a species of aquatic plant in the water shield family known by the common names red cabomba and forked fanwort. It is native to Central and South America and as far north as Cuba and the tip of Florida. It reaches a maximum height between 30 and 80 centimetres and is up to 8 centimetres (3.1 in) wide. It bears purple flowers.
Glenbrook Lagoon is a fresh water lagoon located in Glenbrook, New South Wales at the foot of the Blue Mountains. It is heritage-listed.
Cabomba aquatica is a popular aquarium plant that belongs to the family Cabombaceae and genus Cabomba. It is a perennial aquatic plant that lives in fresh standing water or in lakes and rivers with slight currents.
Mayaca fluviatilis, also known as bog moss, is a perennial herbaceous submerged plant in the monogeneric family Mayacaceae. It is native to Central and South America, the Caribbean, and the United States where it is often sold as an aquarium plant. Through the aquatic plant trade, it has recently become naturalized in Sri Lanka, Singapore, and China. It has been identified in three locations in Australia but more populations are likely in other parts of Australia as well.
Nymphaea prolifera is a species of waterlily naturally found from Mexico to Brazil and northeastern Argentina. Additionally, it has been reported to occur in Uruguay.
Cabomba haynesii is a species of aquatic plant in the family Cabombaceae native to the Caribbean, Central America, and South America.
Cabomba palaeformis is a species of aquatic plant in the family Cabombaceae native to Mexico and Central America.
Cabomba schwartzii is a species of aquatic plant in the family Cabombaceae endemic to North Brazil.
