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 Argentina
The environment of Argentina is highly biodiverse. Biodiversity Flora Subtropical plants dominate the Gran Chaco in the north, with the '' Dalbergia'' genus of trees well represented by Brazilian rosewood and the quebracho tree; also predominant are the wacho white and black algarrobo trees ('' Prosopis alba'' and ''Prosopis nigra''). Savannah-like areas exist in the drier regions nearer the Andes. Aquatic plants thrive in the wetlands of Argentina. In central Argentina the ''humid pampas'' are a true tallgrass prairie ecosystem. In Argentina forest cover is around 10% of the total land area, equivalent to 28,573,000 hectares (ha) of forest in 2020, down from 35,204,000 ha in 1990. In 2020, naturally regenerating forest covered 27,137,000 ha and planted forest covered 1,436,000 ha. Of the naturally regenerating forest 0% was reported to be primary forest (consisting of native tree species with no clearly visible indications of human activity) and around 7% o ...

Cacti Of South America
A cactus (: cacti, cactuses, or less commonly, cactus) is a member of the plant family Cactaceae (), a family of the order Caryophyllales comprising about 127 genera with some 1,750 known species. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. They are native to the Americas, ranging from Patagonia in the south to parts of western Canada in the north, with the exception of ''Rhipsalis baccifera'', which is also found in Africa and Sri Lanka. Cacti are adapted to live in very dry environments, including the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti ...

Cactoideae Genera
The Cactoideae are the largest subfamily of the cactus family, Cactaceae, and are widely distributed throughout the Americas. Cactaceae is the 5th most endangered plant or animal family evaluated globally by the International Union for Conservation of Nature. Around 80% of cactus species belong to this subfamily. The genera of the Cactoideae are characterized by microscopic foliage leaves. All photosynthesis occurs in shoot cortex cells covered by a persistent epidermis and stomata. Another important characteristic of this subfamily is ribbed stems, which enable the inner cortex to expand radially without breaking the shoot surface to absorb large quantities of water.Mauseth, J. D. (2006). Structure–function relationships in highly modified shoots of Cactaceae. ''Annals of Botany, 98''(5), 901-926. , the internal classification of the family (biology), family Cactaceae remained uncertain and subject to change. A classification incorporating many of the insights from the molecu ...

Cereeae
Cereeae is a tribe of cacti belonging to the subfamily Cactoideae containing about 50 genera, divided in 2023 among six subtribes. Description Cereeae are tree-like or shrubby, sometimes climbing plants. Their mostly elongated to spherical, ribbed and thorny shoots are not articulated. The flowers, which usually appear on the side of the shoot, open during the day or at night. Their pericarpels usually have a few scales or are completely glabrous. The fleshy, berry-like, bursting or non-bursting fruits often have a blackening adherent flower remnant. The small to large seeds are oval. The hilum and micropyle of the seeds are fused, one appendage is absent. Taxonomy Phylogeny In classifications before the use of molecular phylogenetic methods, Cereeae was one of nine tribes into which the subfamily Cactoideae was divided. Molecular studies found that these traditional tribes were not monophyletic. A broader circumscription of Cereeae, including Browningieae and Trichocereeae and ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...
