Juncus is a genus of monocotyledonous flowering plants, commonly known as rushes. It is the largest genus in the family Juncaceae, containing around 300 species.
Minuartia is a genus of flowering plants commonly known as sandworts in the family Caryophyllaceae.
Wolffia is a genus of aquatic plants with a cosmopolitan distribution. They include the smallest flowering plants on Earth. Commonly called watermeal or duckweed, these aquatic plants resemble specks of cornmeal floating on the water. They often float together in pairs or form floating mats with related plants, such as Lemna and Spirodela species.
Echinodorus, commonly known as burhead or Amazon sword, is a genus of plants in the family Alismataceae, native to the Western Hemisphere from the central United States to Argentina. Its scientific name is derived from Ancient Greek echius – "rough husk" - and doros – "leathern bottle" - alluding to ovaries, which in some species are armed with persistent styles, forming prickly head of fruit. Some of the species are commonly cultivated in artificial aquatic habitats.
Luronium natans is a species of aquatic plant commonly known as the floating water-plantain. It is the only recognized species in the genus Luronium, native to western and central Europe, from Spain to Britain to Norway east to Ukraine.
Ruellia is a genus of flowering plants commonly known as ruellias or wild petunias. They are not closely related to petunias (Petunia) although both genera belong to the same euasterid clade. The genus was named in honor of Jean Ruelle (1474–1537), herbalist and physician to Francis I of France and translator of several works of Dioscorides.
Valerianella is a genus of flowering plant in family Caprifoliaceae. It includes 23 species native to the Mediterranean Basin of southern Europe and North Africa, western and central Asia, Madeira and the Azores, and Ethiopia and Kenya. Many species formerly placed in Valerianella, including those native to the Americas, have been moved to Valeriana. Plants of Valerianella and Valeriana are sometimes known by the common name corn salad or cornsalad.
Cleomella is a genus of flowering plants. It includes 22 species of native to North America, ranging from southern Mexico through the western and central United States to western and central Canada. Like their relatives, the cleomes, plants of this genus have traditionally been included in the caper family Capparaceae but have recently been moved into a new family, Cleomaceae. Cleomella are annual wildflowers native to the dry and desert regions of western North America. They are similar to cleomes in appearance. They are erect and branching with leaves divided into three leaflets and inflorescences of yellow flowers with long stamens. Cleomella species are known commonly as stinkweeds or simply cleomellas.
Callitriche stagnalis is a perennial aquatic vascular plant species. Also known as pond water-starwort, C. stagnalis, may thrive in a variety of aquatic and subaquatic habitats, specially those exhibiting slowly moving to non-moving water. Although C. stagnalis does not pose a threat to humans, its reproductive rate may pose a threat to native vegetation in areas where it has been introduced, as the resulting dense vegetative mats frequently out-compete native species.
Halymenia a genus of a macroscopic red algae that grows in oceans worldwide.
Ruth Mason was a New Zealand botanist specialising in the taxonomy and ecology of freshwater plants. She was employed at the Department of Scientific and Industrial Research for 35 years undertaking research into aquatic plants, pioneering new techniques for plant preservation and collecting over 13,000 plant specimens in the field. She was awarded life membership by the New Zealand Ecological Society.
Ranunculus trichophyllus, the threadleaf crowfoot, or thread-leaved water-crowfoot, is a plant species in the genus Ranunculus, native to Europe, Asia and North America.
The Antirrhineae are one of the 12 tribes of the family Plantaginaceae. It contains the toadflax relatives, such as snapdragons.
Callitriche brutia, the pedunculate water-starwort, is a dwarf amphibious annual or perennial dicotyledon herb in the genus Callitriche. The common name of this species is water starwort. It colonizes aquatic environments, such as wetlands, lakes, rivers, streams, and pools, and it grows in oligotrophic conditions, meaning it grows in an environment that has little to sustain life. Pedunculate water-starwort was found in Ireland and England, but is now an invasive species due to its resistance to environmental stressors, and its ability to grow in still water.
Callitriche palustris, the vernal water-starwort, narrow-fruited water-starwort, or spiny water starwort, is a species of aquatic plants. It is the type species of its genus.
Callitriche truncata, the short leaved water starwort, is a species of plant in the family Plantaginaceae. It is an aquatic subshrub native to the Mediterranean Basin countries of southern Europe from Spain to Greece and of North Africa from Morocco to Libya, as well as Turkey, Lebanon, and Syria in the eastern Mediterranean, Belgium, the Netherlands, Great Britain, and Ireland in western Europe, eastern European Russia, and the western Himalayas.
