Annona Paludosa
''Annona paludosa'' is a species of plant in the family Annonaceae. It is native to Brazil, French Guiana, Guyana, Suriname and Venezuela. Jean Baptiste Christophore Fusée Aublet, the French pharmacist and botanist who first formally described the species, named it after its swampy ( in Latin) habitat. Description It is a bush reaching 1.2-1.5 meters in height. Its branches have numerous light brown lenticels. Its oblong, membranous leaves are 16-20 by 6-7.5 centimeters and come to a point at their tip. The mature leaves are hairless on their green upper surface, but have woolly rust colored hairs on their reddish lower surfaces. The leaves have 18-20 secondary veins emanating from each side of their midribs. Its petioles are 5 by 3 millimeters, densely covered in woolly hairs, and have a groove on their upper surface. Its flowers are on 10-15 millimeter long peduncles that occur alone or in pairs. The peduncles are covered in woolly hairs and have a bracteole at their ...

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 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 Mon Plaisir garden, and eventually left to establish a new garden at Le Réduit. When Aub ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Plants Described In 1775
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...

Flora Of Venezuela
The flora of Venezuela consists of a huge variety of unique plants; around 38% of the estimated 30,000 species of plants found in the country are endemic to Venezuela. Overall, around 48% of Venezuela's land is forested; this includes over 60% of the Venezuelan Amazon. These rainforests are increasingly endangered by mining and logging activities. Venezuela's habitats range from the Andes mountains in the west to the Amazon Basin rainforest in the south, via extensive Llanos plains and Caribbean coast in the center and the Orinoco River Delta in the east. They include xeric scrublands in the extreme northwest and coastal mangrove forests in the northeast. Its cloud forests and lowland rainforests are particularly rich, for example hosting over 25,000 species of orchids.Dydynski, K; Beech, C (2004). Venezuela'. Lonely Planet. . Retrieved 10 March 2007. p42 These include the ''flor de mayo'' orchid (''Cattleya mossiae''), the national flower. Venezuela's national tree is the '' arag ...

Flora Of Suriname
Biodiversity in Suriname is high, mostly because of the variety of habitats and the temperature. The average annual temperature in the coastal area is between 26° and 28° Celsius. Suriname can be divided into four major ecological zones, namely from north to south; # The young coastal plain # The old coastal plain # The Savannah or Zanderij belt # The interior residual uplands. Habitats and species The coast of Suriname is wild and consists of mud banks, sand beaches, mangrove forests and lagoons. The Guiana current flows along the coast of Suriname. The North Brazil Current, a warm water ocean current, is renamed as the Guiana current. The confusion surrounding its name is due partly to the seasonal change in flow of nearby currents. The mangrove forests have only one story with a height of 20–25 meters. They are almost completely homogenous and dominated by black mangrove (''Avicenna germinans''). The mangrove forests are important as staging and wintering areas for birds, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Guyana
Guyana ( or ), officially the Cooperative Republic of Guyana, is a country on the northern mainland of South America. Guyana is an indigenous word which means "Land of Many Waters". The capital city is Georgetown. Guyana is bordered by the Atlantic Ocean to the north, Brazil to the south and southwest, Venezuela to the west, and Suriname to the east. With , Guyana is the third-smallest sovereign state by area in mainland South America after Uruguay and Suriname, and is the second-least populous sovereign state in South America after Suriname; it is also one of the least densely populated countries on Earth. It has a wide variety of natural habitats and very high biodiversity. The region known as "the Guianas" consists of the large shield landmass north of the Amazon River and east of the Orinoco River known as the "land of many waters". Nine indigenous tribes reside in Guyana: the Wai Wai, Macushi, Patamona, Lokono, Kalina, Wapishana, Pemon, Akawaio and Warao. Histori ...

Flora Of French Guiana
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. 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) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Brazil
The wildlife of Brazil comprises all naturally occurring animals, plants, and fungi in the South American country.

Edward Lewis Sturtevant
Edward Lewis Sturtevant (January 23, 1842 – July 30, 1898) was an American agronomist and botanist who wrote ''Sturtevant's Edible Plants of the World.'' An enormously prolific author, he was considered one of the giants of American agricultural science in his own time. Early life and education E. Lewis Sturtevant was born in Boston, Massachusetts, on January 23, 1842, to Lewis W. Sturtevant (descendant of a family of Puritan ancestry) and Mary Haight (Legett) Sturtevant. Through a common ancestor, Samuel Sturtevant, who emigrated from England to America in the 1640s, he is a distant cousin of the geneticist Alfred Henry Sturtevant. While still a youth, his parents died, and Lewis was raised by an aunt. In 1859 he entered Bowdoin College but left before completing his degree to join the Union Army when the American Civil War broke out in 1861. He served in the 74th Regiment of Maine Volunteers as a captain but was invalided out due to a combined attack of typhoid and malaria in ...

Elaiosome
Elaiosomes ( grc, ἔλαιον ''élaion'' "oil" + ''sóma'' "body") are fleshy structures that are attached to the seeds of many plant species. The elaiosome is rich in lipids and proteins, and may be variously shaped. Many plants have elaiosomes that attract ants, which take the seed to their nest and feed the elaiosome to their larvae. After the larvae have consumed the elaiosome, the ants take the seed to their waste disposal area, which is rich in nutrients from the ant frass and dead bodies, where the seeds germinate. This type of seed dispersal is termed myrmecochory from the Greek "ant" (myrmex) and "circular dance" (khoreíā). This type of symbiotic relationship appears to be mutualistic, more specifically dispersive mutualism according to Ricklefs, R.E. (2001), as the plant benefits because its seeds are dispersed to favorable germination sites, and also because it is planted (carried underground) by the ants. Elaiosomes develop in various ways either from seed ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gynoecium
Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are called ''pi ...
