Mayaca Fluviatilis
''Mayaca fluviatilis'', also known as bog moss, is a perennial herbaceous submerged plant in the monogeneric family Mayacaceae. It is native to Central and South America, the Caribbean, and the United States where it is often sold as an aquarium plant. Through the aquatic plant trade, it has recently become naturalized in Sri Lanka, Singapore, and China. It has been identified in three locations in Australia ( Innisfail and Mossman in Queensland and Taree in New South Wales) but more populations are likely in other parts of Australia as well. Description The species was first described by the French botanist Jean Baptiste Christophore Fusée Aublet as ''La mayaque des rivieres'' in a tributary of the Sinnamary river in Guyana. ''Mayaca fluviatilis'' has soft thin leaves arranged in spirals on white or pale green stems which frequently grow up to one meter in length. Flowers grow on single stalks, 2 to 5 cm long, and are roughly 1 cm in diameter. The flowers of ''Mayaca fluv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Baptiste Christophore Fusée Aublet
Jean Baptiste Christophore Fusée Aublet (November 4, 1720 – May 6, 1778) was a French pharmacist, botanist and one of the earliest botanical explorers in South America.JSTOR He was one of the first botanists to study ethnobotany in the Neotropics. Born in Salon-de-Provence, Aublet left home early and traveled to Grenada, then a French colony, where he became an apothecary's assistant and learned about medicinal plants. A year later he returned to France and continued his studies in natural history, chemistry, and pharmacology. One of his mentors was Bernard de Jussieu, a French naturalist who would later help him with plant identification.Mori He joined the French Indies Company, French East India Company and in 1752 was sent to Mauritius (then known as ''l'Île de France'') to establish a pharmacy and a botanical garden. He became involved in an intense rivalry with Pierre Poivre, a fellow botanist at the Chateau de Mon Plaisir , Mon Plaisir garden, and eventually left to ...

Mayaca
''Mayaca'' is a genus of flowering plants, often placed in its own family, the Mayacaceae (or Mayaceae in earlier systems). In the APG II system of 2003, it is assigned to the order Poales in the clade commelinids. The Cronquist system, of 1981, also recognised such a family and placed it in the order Commelinales in the subclass Commelinidae. The group is widely distributed in Latin America from Mexico to Argentina, as well as in the West Indies, the southeastern United States, and central Africa. Species Eighteen or so species names have been proposed, but only 5 are accepted as distinct. * '' Mayaca baumii'' Gürke - Congo-Brazzabille, Zaïre, Angola, Zambia * '' Mayaca fluviatilis'' Aubl. - southeastern United States from Texas to North Carolina; West Indies (Cuba, Jamaica, Trinidad); Latin America from central Mexico to Argentina * '' Mayaca kunthii'' Seub. - Venezuela, Brazil, Uruguay * '' Mayaca longipes'' Mart. ex Seub. - Venezuela, Brazil, Colombia, the Guianas * ...

Flora Of Northern America
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Hydrilla Verticillata
''Hydrilla'' (waterthyme) is a genus of aquatic plant, usually treated as containing just one species, ''Hydrilla verticillata'', though some botanists divide it into several species. It is native to the cool and warm waters of the Old World in Asia, Africa and Australia, with a sparse, scattered distribution; in Australia from Northern Territory, Queensland, and New South Wales.Flora Europaea''Hydrilla''/ref>Flora of Taiwan''Hydrilla'' The stems grow up to 1–2 m long. The leaves are arranged in whorls of two to eight around the stem, each leaf 5–20 mm long and 0.7–2 mm broad, with serrations or small spines along the leaf margins; the leaf midrib is often reddish when fresh. It is monoecious (sometimes dioecious), with male and female flowers produced separately on a single plant; the flowers are small, with three sepals and three petals, the petals 3–5 mm long, transparent with red streaks. It reproduces primarily vegetatively by fragmentation and by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perianth
The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower. It is a structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone. The term ''perianth'' is derived from Greek περί (, "around") and άνθος (, "flower"), while ''perigonium'' is derived from περί () and γόνος (, "seed, sex organs"). In the mosses and liverworts (Marchantiophyta), the perianth is the sterile (neither male nor female) tubelike tissue that surrounds the female reproductive structure or developing sporophyte. Flowering plants In flowering plants, the perianth may be described as being either dichlamydeous/heterochlamydeous in which the calyx and corolla are clearly separate, or homochlamydeous, in which they are indistinguishable (and the sepals and petals are collectively referred to as tepals). When the perianth is in two whorls, it is desc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 Etymology The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively, the sepals are called the ''calyx'' (plural: calyces), the outermost Whorl (botany), whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. The Latin ''calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet'; both words have been used interchangeably in botanical Latin. Description The term ''tepal'' is usually applied when the parts of the perianth are difficult to distinguish, e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Herbaceous Plant
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the '' Shorter Oxford English Dictionary'' defines "herb" as: # "A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; # "A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: # "Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; # "BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, th ...
