Philydraceae
Philydraceae is a family of flowering plants composed of three genera and a total of six known species. Such a family has not been recognized by many taxonomists. The APG II system, of 2003 (unchanged from the APG system, of 1998), does recognize such a family and places it in the order Commelinales, in the clade commelinids, in the monocots. It consists of only very few species of perennial, tropical plants in Southeast Asia and Australia Australia, officially the Commonwealth of Australia, is a Sovereign state, sovereign country comprising the mainland of the Australia (continent), Australian continent, the island of Tasmania, and numerous List of islands of Australia, sma ....

Commelinales
Commelinales is an order of flowering plants. It comprises five families: Commelinaceae, Haemodoraceae, Hanguanaceae, Philydraceae, and Pontederiaceae. All the families combined contain over 885 species in about 70 genera; the majority of species are in the Commelinaceae. Plants in the order share a number of synapomorphies that tie them together, such as a lack of mycorrhizal associations and tapetal raphides. Estimates differ as to when the Commelinales evolved, but most suggest an origin and diversification sometime during the mid- to late Cretaceous. Depending on the methods used, studies suggest a range of origin between 123 and 73 million years, with diversification occurring within the group 110 to 66 million years ago. The order's closest relatives are in the Zingiberales, which includes ginger, bananas, cardamom, and others.Stevens, P. F. (2001 onwards). Angiosperm Phylogeny Website. Version 9, November 2011.

Philydrum Lanuginosum
''Philydrum'' is a genus of tufted, herbaceous, aquatic macrophyte plants, one of three genera constituting the plant family Philydraceae. ''Philydrum lanuginosum'' is the sole known species. They are commonly known as frogsmouths and woolly waterlilies. Woolly waterlilies occur naturally across south and east Asia, including India, S. China, Taiwan, Japan, Malaysia, Burma, Thailand, Vietnam; across Malesia including New Guinea; across northern and eastern Australia and the Pacific Islands. In Australia they grow naturally in wetlands in northern WA, NT, Qld, NSW and Vic. They have spongy, soft, hairy, herbaceous foliage. The foliage grows upright in tufts up to high, from short–creeping and branching stems rooted in the mud. The stems grow up taller than the leaves, becoming green and woolly spikes up to high. The spikes successively open many, attractive, fine yellow flowers. Long, pointed, green and woolly bracts up to enclose each bud. As the spike grows, each succes ...

APG System
The APG system (Angiosperm Phylogeny Group system) of plant classification is the first version of a modern, mostly molecular-based, system of plant taxonomy. Published in 1998 by the Angiosperm Phylogeny Group, it was replaced by the improved APG II in 2003, APG III system in 2009 and APG IV system in 2016. History The original APG system is unusual in being based, not on total evidence, but on the cladistic analysis of the DNA sequences of three genes, two chloroplast genes and one gene coding for ribosomes. Although based on molecular evidence only, its constituent groups prove to be supported by other evidence as well, for example pollen morphology supports the split between the eudicots and the rest of the former dicotyledons. The system is rather controversial in its decisions at the family level, splitting a number of long-established families and submerging some other families. It also is unusual in not using botanical names above the level of order, that is, an orde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Johann Heinrich Friedrich Link
Johann Heinrich Friedrich Link (2 February 1767 – 1 January 1851) was a German naturalist and botanist. Biography Link was born at Hildesheim as a son of the minister August Heinrich Link (1738–1783), who taught him love of nature through collection of 'natural objects'. He studied medicine and natural sciences at the Hannoverschen Landesuniversität of Göttingen, and graduated as MD in 1789, promoting on his thesis ''"Flora der Felsgesteine rund um Göttingen"'' (Flora of the rocky beds around Göttingen). One of his teachers was the famous natural scientist Johann Friedrich Blumenbach (1752–1840). He became a private tutor (''Privatdozent'') in Göttingen. In 1792 he became the first professor of the new department of chemistry, zoology and botany at the University of Rostock. During his stay at Rostock, he became an early follower of the antiphlogistic theory of Lavoisier, teaching about the existence of oxygen instead of phlogiston. He was also a proponent of the ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
