Flora (pl.: 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 . [1] Sometimes bacteria and fungi are also referred to as flora as in the terms gut flora or skin flora . [2] [3] [4]
The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. [5] 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. [6]
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 interchangeably. [7] [8]
Plants are grouped into floras based on region (floristic regions), period, special environment, or climate. Regions can be distinct habitats like mountain vs. flatland. Floras can mean plant life of a historic era as in fossil flora. Lastly, floras may be subdivided by special environments:
The flora of a particular area or time period can be documented in a publication also known as a "flora" (often capitalized as "Flora" to distinguish the two meanings when they might be confused). Floras may require specialist botanical knowledge to use with any effectiveness. Traditionally they are books, but some are now published on CD-ROM or websites.
Simon Paulli's Flora Danica of 1648 is probably the first book titled "Flora" to refer to the plant world of a certain region. It mainly describes medicinal plants growing in Denmark. The Flora Sinensis by the Polish Jesuit Michał Boym is another early example of a book titled "Flora". [9] However, despite its title it covered not only plants but also some animals of the region, that is China and India. [6]
A published flora often contains diagnostic keys. Often these are dichotomous keys, which require the user to examine a plant repeatedly, and decide which one of two alternatives given best applies to the plant.
Vegetation is an assemblage of plant species and the ground cover they provide. It is a general term, without specific reference to particular taxa, life forms, structure, spatial extent, or any other specific botanical or geographic characteristics. It is broader than the term flora which refers to species composition. Perhaps the closest synonym is plant community, but vegetation can, and often does, refer to a wider range of spatial scales than that term does, including scales as large as the global. Primeval redwood forests, coastal mangrove stands, sphagnum bogs, desert soil crusts, roadside weed patches, wheat fields, cultivated gardens and lawns; all are encompassed by the term vegetation.
Malesia is a biogeographical region straddling the Equator and the boundaries of the Indomalayan and Australasian realms, and also a phytogeographical floristic region in the Paleotropical Kingdom. The original definition by the World Geographical Scheme for Recording Plant Distributions included Papuasia, but this was split off in its 2001 version.
A phytochorion, in phytogeography, is a geographic area with a relatively uniform composition of plant species. Adjacent phytochoria do not usually have a sharp boundary, but rather a soft one, a transitional area in which many species from both regions overlap. The region of overlap is called a vegetation tension zone.
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is flora, and for fungi, it is funga. Flora, fauna, funga and other forms of life are collectively referred to as biota. Zoologists and paleontologists use fauna to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics.
In microbiology, collective bacteria and other microorganisms in a host are historically known as flora. Although microflora is commonly used, the term microbiota is becoming more common as microflora is a misnomer. Flora pertains to the Kingdom Plantae. Microbiota includes Archaea, Bacteria, Fungi and Protists. Microbiota with animal-like characteristics can be classified as microfauna.
The California Native Plant Society (CNPS) is a California environmental non-profit organization that seeks to increase understanding of California's native flora and to preserve it for future generations. The mission of CNPS is to conserve California native plants and their natural habitats, and increase understanding, appreciation, and horticultural use of native plants throughout the entire state and California Floristic Province.
Phytogeography or botanical geography is the branch of biogeography that is concerned with the geographic distribution of plant species and their influence on the earth's surface. Phytogeography is concerned with all aspects of plant distribution, from the controls on the distribution of individual species ranges to the factors that govern the composition of entire communities and floras. Geobotany, by contrast, focuses on the geographic space's influence on plants.
The California Floristic Province (CFP) is a floristic province with a Mediterranean-type climate located on the Pacific Coast of North America with a distinctive flora similar to other regions with a winter rainfall and summer drought climate like the Mediterranean Basin. This biodiversity hotspot is known for being the home of the Sierran giant sequoia tree and its close relative the coast redwood. In 1996, the Province was designated as a biodiversity hotspot allowing it to join ranks among 33 other areas in the world with many endemic species. To be named a biodiversity hotspot, an area has to contain species and plant life that cannot be found anywhere else in the world. The California Floristic Province is home to over 3,000 species of vascular plants, 60% of which are endemic to the province.
The wildlife of Brazil comprises all naturally occurring animals, plants, and 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), amphibians (1,188), snakes (430), 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. Approximately two-thirds of all species worldwide are found in tropical areas, often coinciding with developing countries such as Brazil. Brazil is second only to Indonesia as the country with the most endemic species.
The native flora of the United States includes about 17,000 species of vascular plants, plus tens of thousands of additional species of other plants and plant-like organisms such as algae, lichens and other fungi, and mosses. About 3,800 additional non-native species of vascular plants are recorded as established outside of cultivation in the U.S., as well as a much smaller number of non-native non-vascular plants and plant relatives. The United States possesses one of the most diverse temperate floras in the world, comparable only to that of China.
The flora of Australia comprises a vast assemblage of plant species estimated to over 21,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (Banksia), Myrtaceae, and Fabaceae.
The Wombat State Forest is located 50 kilometres (31 mi) west of Melbourne, Victoria, Australia, between Woodend and Daylesford, at the Great Dividing Range. The forest is approximately 70,000 hectares in size and sits upon Ordovician or Cenozoic sediments. The Bullarook Wombat State Forest was proclaimed in 1871.
Cape Lowland Freshwater Wetland is a critically endangered vegetation type of the Western Cape, South Africa.
The biodiversity of Tasmania is of exceptional biological and paleoecological interest. A state of Australia, it is a large South Pacific archipelago of one large main island and a range of smaller islands. The terrain includes a variety of reefs, atolls, many small islands, and a variety of topographical and edaphic regions on the largest island, all of which promote the development of unusually concentrated biodiversity. During long periods geographically and genetically isolated, it is known for its unique flora and fauna. The region's climate is oceanic.

According to IBGE (2004), Brazil has its territory occupied by six terrestrial biomes and one marine biome.
A remnant natural area, also known as remnant habitat, is an ecological community containing native flora and fauna that has not been significantly disturbed by destructive activities such as agriculture, logging, pollution, development, fire suppression, or non-native species invasion. The more disturbed an area has been, the less characteristic it becomes of remnant habitat. Remnant areas are also described as "biologically intact" or "ecologically intact."

An escaped plant is a cultivated plant that has escaped from agriculture, forestry or garden cultivation and has become naturalized in the wild. Usually not native to an area, escaped plants may become invasive. Therefore, escaped plants are the subject of research in invasion biology.
In life sciences, funga is a recent term for the kingdom fungi similar to the longstanding fauna for animals and flora for plants. The term seeks to simplify projects oriented toward implementation of educational and conservation goals. An informal meeting held during the IX Congreso Latinoamericano de Micología resulted in a proposal for the term in 2018; alternative terms were also proposed and discussed. Funga was recommended by the IUCN in 2021. The term highlights parallel terminology referring to treatments of these macroorganisms of particular geographical areas.
