Nymphoides Spinulosperma
''Nymphoides spinulosperma'', commonly known as marbled marshwort, is an aquatic plant of the family Menyanthaceae Menyanthaceae is a family of aquatic and wetland plants in the order Asterales. There are approximately 60-70 species in six genera distributed worldwide. The simple or compound leaves arise alternately from a creeping rhizome. In the submers ... native to eastern Australia. It was described in 1997. ''Nymphoides spinulosperma'' is a perennial herb with stems up to 1.5 cm (0.6 in) long. The oval to circular leaves are 2.5–12 cm long by 2–11 cm wide, with a heart-shaped (cordate) base. There is a pinkspot at the base of the leaf where it attaches to the petiole. The flowers appear in summer and autumn, up to 5.5 cm across and bright yellow with fringed petals. It has been recorded from isolated waterways in Victoria, New South Wales and Queensland. Its habitat is slowly-moving or still water to 1 m in depth. Not often seen in culti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helen Isobel Aston
Helen Isobel Aston (26 March 1934 – 17 March 2020) was an Australian botanist and ornithologist. Biography Aston completed her Bachelor of Science in 1957 with majors in botany and zoology from the University of Melbourne. Aston worked at the National Herbarium of Victoria from 1956 to 1991, where she became one of Australia's leading authorities on freshwater vascular plants. The National Herbarium of Victoria holds the majority of Aston's herbarium, almost 3,000 specimens, with duplicates distributed around Australian Herbaria including AD, BRI, CANB, HO, NE, NSW and PERTH. Aston is probably best known for her book ''Aquatic Plants of Australia'' published in 1973 by Melbourne University Press. Aston has represented Australian herbaria as the Australian Botanical Liaison Officer in 1974 with the Royal Botanic Gardens, Kew, United Kingdom. Aston edited the in-house journal, '' Muelleria'', from 1977 to 1988. Standard author abbreviation Selected published names ...

Menyanthaceae
Menyanthaceae is a family of aquatic and wetland plants in the order Asterales. There are approximately 60-70 species in six genera distributed worldwide. The simple or compound leaves arise alternately from a creeping rhizome. In the submersed aquatic genus ''Nymphoides'', leaves are floating and support a lax, umbellate or racemose inflorescence. In other genera the inflorescence is erect and consists of one (e.g., '' Liparophyllum'') to many flowers. The sympetalous, insect-pollinated flowers are five-parted and either yellow or white. The petals are ciliate or adorned with lateral wings. Fruit type is a capsule. Species of Menyanthaceae are found worldwide. The genera ''Menyanthes'' and ''Nephrophyllidium'' grow only in the northern hemisphere, while '' Liparophyllum'' and '' Villarsia'' occur only in the southern hemisphere. ''Nymphoides'' species have a cosmopolitan distribution. Menyanthaceae species are of economic importance as ornamental water garden plants, with ' ...

Nymphoides
''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. Species of ''Nymphoides'' are sold as aquarium plants, including the "banana plant", '' N. aquatica'' and the "water snowflake", '' N. indica''. Species native to the United States are '' N. cordata'' in the northeast and '' N. aquatica'' in the southeast. ''Nymphoides peltata'' is native to Europe and Asia, but can be found in the United States as an invasive aq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Plants
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water i ...

Plants Described In 1997
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...
