In context of biogeography, Neotropic or Neotropical means one of the world's eight terrestrial ecozones. This ecozone includes South and Central America, the Mexican lowlands, the Caribbean islands, and southern Florida, because these regions share a large number of plant and animal groups. It is sometimes used as a synonym for the tropical area of South America, although the ecozone also includes temperate southern South America. Its fauna and flora are distinct from the Nearctic (which includes most of North America) because of the long separation of the two continents. The formation of the Isthmus of Panama joined the two continents 2 to 3 million years ago. The Neotropic includes more tropical rainforest than any other ecozone. They extend from southern Mexico through Central America and northern South America to southern Brazil and include the Amazon Rainforest. These rainforest ecoregions are one of the most important reserves of biodiversity on Earth. Extensive deforestation in the late 20th century has reduced this diversity to a degree.

The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropical terrestrial ecoregions of the Americas and the entire South American temperate zone. Definition In biogeography, the Neotropic or Neotropical realm is one of the eight terrestrial realms. This realm includes South America, Central America, the Caribbean islands, and southern North America. In Mexico, the Yucatán Peninsula and southern lowlands, and most of the east and west coastlines, including the southern tip of the Baja California Peninsula are Neotropical. In the United States southern Florida and coastal Central Florida are considered Neotropical. The realm also includes temperate southern South America. In contrast, the Neotropical Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic kingdom. The Neotropic is delimited by similarities in fauna or flora. Its fauna and flora are distinct from the Nearctic realm (which includes most of North America) because of the long separation of the two continents. The formation of the Isthmus...

Passiflora, known also as the passion flowers or passion vines, is a genus of about 550 species of flowering plants, the type genus of the family Passifloraceae. They are mostly tendril-bearing vines, with some being shrubs or trees. They can be woody or herbaceous. Passion flowers produce regular and usually showy flowers with a distinctive corona. There can be as many as eight coronal series, as in the case of P. xiikzodz. The flower is pentamerous and ripens into an indehiscent fruit with numerous seeds. List of species Distribution Passiflora has a largely neotropic distribution, unlike other genera in the family Passifloraceae, which includes more Old World species (such as the genus Adenia). The vast majority of Passiflora are found in Mexico, Central America, the United States and South America, although there are additional representatives in Southeast Asia and Oceania. New species continue to be identified...
