The Amazon River is one of Earth's longest rivers, flowing 4,000 miles across South America from the Andes Mountains to the Atlantic Ocean. The immense area drained by the Amazon River and its tributaries is known as the Amazon Basin or Amazonia. It is home to an important natural reservoir of plant and animal diversity: the Amazon rain forest, Earth's largest tropical rain forest, whose original extent covered an area two-thirds the size of the United States. The Amazon Basin also contains many other habitats—from dry forests to dry or super-wet savannas, mountains, and rocky hills—each with its own rich composition of species. Altogether, the Amazon Basin is home to at least 30,000 different species of ferns, flowering plants and gymnosperms (the first seed plants such as cone-bearing conifers).

Although The New York Botanical Garden was founded in 1891, in a sense its history of scientific work in Amazonia began a decade earlier when Henry Hurd Rusby, future Garden scientist and colleague of founding director Nathaniel Lord Britton, descended the Andes Mountains and arrived at Rurrenabaque, Bolivia. The collections Rusby made on that expedition formed part of the core of the Garden's fledgling herbarium. Now with nearly 50 years of continuous collaboration with in-country colleagues in various parts of the Amazon Basin, Botanical Garden scientists continue to co-lead efforts to discover, understand, conserve, and manage its incomparable plant diversity.
