Pontederaceae
Pontederiaceae is a family of flowering plants. The APG IV system of 2016 (unchanged from the APG III system of 2009, the APG II system of 2003 and the APG system of 1998) places the family in the order Commelinales, in the commelinid clade, in the monocots. It is a small family of heterostylous aquatic plants, occurring in tropical and subtropical waters. Charles Darwin was interested in the specialized form of heterostyly found in the family, known as tristyly. Not all of the species are heterostylous. The family contains two genera with around 40 known species. It is best known for the water hyacinth (''Pontederia crassipes''), which is an invasive species in many waterways. The highly modified '' Heteranthera gardneri'' is a submerged aquatic with a two-flowered pseudanthium. Taxonomy The two genera within this family are: *''Heteranthera'' Ruiz & Pav.

Subtropics
The subtropical zones or subtropics are geographical and climate zones to the north and south of the tropics. Geographically part of the temperate zones of both hemispheres, they cover the middle latitudes from to approximately 35° north and south. The horse latitudes lie within this range. Subtropical climates are often characterized by hot summers and mild winters with infrequent frost. Most subtropical climates fall into two basic types: humid subtropical (Koppen climate Cfa), where rainfall is often concentrated in the warmest months, for example Southeast China and the Southeastern United States, and dry summer or Mediterranean climate (Koppen climate Csa/Csb), where seasonal rainfall is concentrated in the cooler months, such as the Mediterranean Basin or Southern California. Subtropical climates can also occur at high elevations within the tropics, such as in the southern end of the Mexican Plateau and in Da Lat of the Vietnamese Central Highlands. The six climate cl ...

Monochoria
''Monochoria'' was originally a genus of aquatic plants in the water hyacinth family, Pontederiaceae. Currently, it has been reduced to a subgenus of Pontederia, ''Pontederia'' subg. ''Monochoria'', represented by ten species (listed below). Its species are native to tropical and subtropical Africa, Asia, and Oceania. They live in the water or in wet soils. They produce leaves on long petioles and some are cultivated for their attractive flowers. Species *'' Pontederia africana'' (Solms) M.Pell. & C.N.Horn *''Pontederia australasica'' (Ridl.)

Eichhornia
''Eichhornia'', commonly called water hyacinths, was a polyphyletic genus of the aquatic flowering plants family Pontederiaceae. Since it was consistently recovered in three independent lineages, it has been sunk into ''Pontederia'', together with '' Monochoria''. Each of the three lineages is currently recognized as subgenera in ''Pontederia'': * ''Pontederia'' subg. ''Cabanisia'', which includes '' P. meyeri'', '' P. paniculata'' (the Brazilian water hyacinth), and '' P. paradoxa'' * ''Pontederia'' subg. ''Oshunae'', which includes the common water hyacinth, '' P. crassipes'' * ''Pontederia'' subg. ''Eichhornia'', which includes '' P. azurea'', '' P. diversifolia'', '' P. heterosperma'', and '' P. natans'' ''Pontederia'' subg. ''Eichhornia'' is pantropical, centered in South America but with '' P. natans'' being endemic to continental Africa and Madagascar. The other three species are restricted to the Neotropics.

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pontederia
''Pontederia'' is a genus of tristylous aquatic plants, members of which are commonly known as pickerel weeds. ''Pontederia'' is endemic to the Americas, distributed from Canada to Argentina, where it is found in shallow water or on mud. The genus was named by Linnaeus in honour of the Italian botanist Giulio Pontedera. ''Pontederia'' plants have large waxy leaves, succulent stems and a thick pad of fibrous roots. The roots give rise to rhizomes that allow rapid colonization by vegetative reproduction. Species are perennial, and produce a large spike of flowers in the summer. There is a species of bee ('' Dufourea novaeangliae'') that exclusively visits ''Pontederia cordata''; waterfowl also eat the fruit of the plant. ''Pontederia cordata'' and '' Pontederia crassipes'' (formerly known as ''Eichhornia crassipes''), have become invasive in many tropical and temperate parts of the globe, but are, on the other hand, efficient biological filters of polluted water in constructed w ...

Ruiz Y Pavón
The Spanish surname Ruiz originates from the Germanic personal name " Hrodric" which is composed of the elements "Hrōd", meaning "renown", and "rīc", meaning "power(ful)", thus "famous ruler". Ruiz is a patronymic from the personal name Ruy, a short form of Rodrigo, meaning "son of Roderick". Its roots can be traced back to the Visigoths, the Germanic tribe which ruled in the Iberian Peninsula between the 5th and 8th centuries.

Heteranthera
''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 America and Africa. They live in the water or in wet soils. They produce leaves on long petioles and some are cultivated for their attractive flowers. Leaves are of two types - linear and submerged or orbicular and floating. Some species have cleistogamic flowers. Selected species *'' Heteranthera callifolia'' (syn. ''H. callaefolia'') *''Heteranthera dubia'' ( Jacq.)

Pseudanthium
A pseudanthium (Greek for "false flower"; ) is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower heads, composite flowers, or capitula, which are special types of inflorescences in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped together to form a single flower-like structure. Pseudanthia take various forms. The real flowers (the florets) are generally small and often greatly reduced, but the pseudanthium itself can sometimes be quite large (as in the heads of some varieties of sunflower). Pseudanthia are characteristic of the daisy and sunflower family (Asteraceae), whose flowers are differentiated into ray flowers and disk flowers, unique to this family. The disk flowers in the center of the pseudanthium are actinomorphic and the corolla is fused into a tube. Flowers on the periphery are zygomorp ...
