Antonio José Cavanilles
Antonio José Cavanilles (16 January 1745 – 5 May 1804) was a leading Spanish taxonomic botanist, artist and one of the most important figures in the 18th century period of Enlightenment in Spain. Cavanilles is most famous for his 2-volume book on Spanish flora, published in 1795 and titled ‘Observations on the Natural History, Geography and Agriculture of the Kingdom of Valencia’.He named many plants, particularly from Oceania. He named at least 100 genera, about 54 of which were still used in 2004, including ''Dahlia'', '' Calycera'', '' Cobaea'', '' Galphimia'', and '' Oleandra''. Biography Cavanilles was born in Valencia. He lived in Paris from 1777 to 1781, where he followed careers as a clergyman and a botanist, thanks to André Thouin and Antoine Laurent de Jussieu. He was one of the first Spanish scientists to use the classification method invented by Carl Linnaeus. Early life and education Antonio José Cavanilles was born on January 16, 1745, in Valenc ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ...

Francoaceae
The Francoaceae are a small family of flowering plants in the order Geraniales, including the genera '' Francoa'', commonly known as bridal wreaths. The Francoaceae are recognized as a family under various classification schemes. Under the 2009 APG III system the Francoaceae were included within the Melianthaceae. In the 2016 APG IV system the Francoaceae are again recognized as a family, with Melianthaceae included in the circumscription of Francoaceae. Genera , Plants of the World Online included the following genera in Francoaceae: *'' Balbisia'' Cav. *'' Bersama'' Fresen. *'' Dimorphopetalum'' Bertero *'' Francoa'' Cav. *'' Greyia'' Hook. & Harv. *'' Melianthus'' L. *'' Rhynchotheca'' Ruiz & Pav. *'' Viviania'' Cav.

United States Department Of Agriculture
The United States Department of Agriculture (USDA) is an executive department of the United States federal government that aims to meet the needs of commercial farming and livestock food production, promotes agricultural trade and production, works to assure food safety, protects natural resources, fosters rural communities and works to end hunger in the United States and internationally. It is headed by the secretary of agriculture, who reports directly to the president of the United States and is a member of the president's Cabinet. The current secretary is Brooke Rollins, who has served since February 13, 2025. Approximately 71% of the USDA's $213 billion budget goes towards nutrition assistance programs administered by the Food and Nutrition Service (FNS). The largest component of the FNS budget is the Supplemental Nutrition Assistance Program (formerly known as the 'Food Stamp' program), which is the cornerstone of USDA's nutrition assistance. The United Stat ...

Agricultural Research Service
The Agricultural Research Service (ARS) is the principal in-house research agency of the United States Department of Agriculture (USDA). ARS is one of four agencies in USDA's Research, Education and Economics mission area. ARS is charged with extending the nation's scientific knowledge and solving agricultural problems through its four national program areas: nutrition, food safety and quality; animal production and protection; natural resources and sustainable agricultural systems; and crop production and protection. ARS research focuses on solving problems affecting Americans every day. The ARS Headquarters is located in the Jamie L. Whitten Building on Independence Avenue in Washington, D.C., and the headquarters staff is located at the George Washington Carver Center (GWCC) in Beltsville, Maryland. For 2018, its budget was $1.2 billion. For 2023, the budget grew to $1.9 billion. Mission ARS conducts scientific research for the American public. Their main focus is on research ...

Geraniales Genera
Geraniales is a small order of flowering plants, included within the rosid subclade of eudicots. The largest family in the order is Geraniaceae with over 800 species. In addition, the order includes the smaller Francoaceae with about 40 species. Most Geraniales are herbaceous, but there are also shrubs and small trees. Flower morphology of the Geraniales is rather conserved. They are usually perfectly pentamerous and pentacyclic without fused organs besides the carpels of the superior gynoecium. The androecium is obdiplostemonous. Only a few genera are tetramerous ('' Francoa, Tetilla, Melianthus''). In some genera some stamens (''Pelargonium'') or a complete whorl of stamens are reduced ('' Erodium, Melianthus''). In the genera '' Hypseocharis'' and '' Monsonia'' there are 15 instead of the usual ten stamens. Most genera bear nectariferous flowers. The nectary glands are formed by the receptacle and are localised at the bases of the antesepalous stamens. The economic imp ...

Plants Described In 1804
Plants are the eukaryotes that form the Kingdom (biology), kingdom Plantae; they are predominantly Photosynthesis, photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular organism, multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts ...

Flora Of Brazil
The wildlife of Brazil comprises all naturally occurring animals, plants, and fungus, fungi in the South American country. Home to 60% of the Amazon Rainforest, which accounts for approximately one-tenth of all species in the world, Brazil is considered to have the greatest biodiversity of any country on the planet. It has the most known species of plants (60,000), freshwater fish (3,000), Amphibian, amphibians (1,188), Snake, snakes (430), Insect, insects (90,000) and mammals (775). It also ranks third on the list of countries with the most bird species (1,971) and the third with the most reptile species (848). The number of fungal species is unknown (+3,300 species).Da Silva, M. and D.W. Minter. 1995. ''Fungi from Brazil recorded by Batista and Co-workers''. Mycological Papers 169.

Flora Of Southern South 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) was ...
