The Herbarium of the National Museum (R) of the Department of Botany of the National Museum (Federal University of Rio de Janeiro) was founded in 1831, being the first herbarium in Brazil and one of the largest in Latin America. The herbarium encompasses approximately 500,000 specimens. The algae collection (R-Algae) includes material collected by many foreign naturalists, mainly during the 19th century, covering distinct aquatic environments from Brazil and abroad (e.g. E. Ule, P. von Luetzelburg, Lenormand, Prouet, Rabenhorst collections).
