Heteranthera Mexicana
''Heteranthera'' is a genus of aquatic plants in the water hyacinth family, Pontederiaceae, known generally as mud plantains. Species of this genus are native to tropical and subtropical Americas, America and Africa. They live in the water or in wet soils. They produce leaves on long Petiole (botany), petioles and some are cultivated for their attractive flowers. Leaves are of two types - linear and submerged or orbicular and floating.

Heteranthera Limosa
''Heteranthera limosa'' is an annual flowering plant in the Pontederiaceae, water hyacinth family known by the common names ducksalad and blue mudplantain. It grows in shallow water or on mud. It is considered a threatened species in parts of the central United States, and an invasive species weed in California, where it is a nuisance in Paddy field, rice paddies. It is also occasional in Florida waterways. Description ''Heteranthera limosa'' is a polymorphic annual growing 2 to 6 inches tall. It looks different depending on the type of habitat it is growing in; plants in water look different than those growing on muddy ground. It is easily confused with other closely related species, so reliable identification is based on flowering plants. It has thick, spade-shaped green leaves with parallel veins. When plants are grown in water the leaves may be above or below the water surface, with submerged leaves linear in shape. The branching stems are creeping and maybe as long as 15 inc ...

Nikolaus Joseph Von Jacquin
Nikolaus Joseph Freiherr von Jacquin (16 February 172726 October 1817) was a scientist who studied medicine, chemistry and botany. Biography Born in Leiden in the Netherlands, he studied medicine at Leiden University, then moved first to Paris and afterward to Vienna. In 1752, he studied under Gerard van Swieten in Vienna. Between 1755 and 1759, Jacquin was sent to the West Indies, Central America, Venezuela and New Granada by Francis I to collect plants for the Schönbrunn Palace, and amassed a large collection of animal, plant and mineral samples. In 1797, Alexander von Humboldt profited from studying these collections and conversing with Jacquin in preparation of his own journey to the Americas. In 1763, Jacquin became professor of chemistry and mineralogy at the Bergakademie Schemnitz (now Banská Štiavnica in Slovakia). In 1768, he was appointed Professor of Botany and Chemistry and became director of the botanical gardens of the University of Vienna. For his work ...

Sereno Watson
Sereno Watson (December 1, 1826 in East Windsor Hill, Connecticut – March 9, 1892 in Cambridge, Massachusetts) was an American botanist. Graduating from Yale in 1847 in Biology, he drifted through various occupations until, in California, he joined the Clarence King Expedition and eventually became its expedition botanist. Appointed by Asa Gray as assistant in the Gray Herbarium of Harvard University in 1873, he later became its curator, a position he maintained until his death. Watson was elected a Fellow of the American Academy of Arts and Sciences in 1874, and a member of the National Academy of Sciences in 1889.

Carl Ludwig Willdenow
Carl Ludwig Willdenow (22 August 1765 – 10 July 1812) was a German botanist, pharmacist, and plant taxonomist. He is considered one of the founders of phytogeography, the study of the geographic distribution of plants. Willdenow was also a mentor of Alexander von Humboldt, one of the earliest and best known phytogeographers. He also influenced Christian Konrad Sprengel, who pioneered the study of plant pollination and floral biology. Biography Willdenow was born in Berlin and studied medicine and botany at the University of Halle. After studying pharmaceutics at Wieglieb College, Langensalza and in medicine at Halle, he returned to Berlin to work at his father's pharmacy located in the Unter den Linden. His early interest in botany was kindled by his uncle J. G. Gleditsch and he started a herbarium collection in his teenage years. In 1794 he became a member of the Berlin Academy of Sciences. He was a director of the Botanical garden of Berlin from 1801 until his death. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olof Swartz
Olof Peter Swartz (21 September 1760 – 19 September 1818) was a Swedish botanist and taxonomist. He is best known for his taxonomic work and studies into pteridophytes. Biography Olof Swartz attended the University of Uppsala where he studied under Carl Linnaeus the Younger (1741–1783) and received his doctorate in 1781. He first traveled in 1780 to Lapland in the company of several other botanists. In 1783 he sailed for North America and the West Indies, primarily in the area of Jamaica and Hispaniola, to collect botanical specimens. His botanical collection, of an impressive 6000 specimens, is now held by the Swedish Museum of Natural History, as part of the Regnellian herbarium. By 1786 he left for London to prepare his collection. There he met naturalist Joseph Banks (1743–1820), who was impressed with his knowledge of Botany. He was offered a position with the British East India Company as a travelling physician, but turned it down, and returned to ...

Conway MacMillan (August 26, 1867 – June 5, 1929) was an American botanist from Minnesota. Life MacMillan was born in Hillsdale, Michigan. He took his first and master's degrees in Nebraska. After this he spent a year at Johns Hopkins University followed by a year at Harvard. Macmillan worked at the University of Minnesota until he resigned over the problems with Josephine Tilden's "Minnesota Seaside Station" in Canada. MacMillan headed the research station where 25 to 30 students would study each summer. Under his leadership the land gathered a number of buildings and a three-mile road was built from Port Renfrew A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers.

Heteranthera Dubia
''Heteranthera dubia'', commonly called water stargrass or grassleaf mudplantain, is a species of aquatic plant in the pickerel-weed family (Pontederiaceae). It is native to North and Central America where it is widespread from Canada to Guatemala. It lives submerged in freshwater such as rivers and lakes. It can be found as deep as 5.5 meters, to as shallow as stranded on the shoreline. It is most abundant in alkaline waters. ''Heteranthera dubia'' is a perennial with much variation in its appearance. The leaves are different sizes and shapes across individuals, partly genetic variation and partly response to water conditions, for example, the speed and turbulence of surrounding currents. Submersed individuals also have a different stem and leaf morphology from those that occur partially or completely out of the water. Its inflorescence bears a single short-lived flower that blooms in the morning and wilts in the evening. It has six yellow perianth parts each less than a centim ...
