Guarana, growing in the Amazon below El Coca, Orellana Province.  A trailing or climbing vine with striking flowers, Guarana is common to the Amazon basin, especially in Brazil, and are also cultivated for their high-caffeine beans, which are as much as three times higher in caffeine than coffee beans.  Guarana is a common additive in energy drinks, and very popular in Peru and Brazil where it is cultivated on a large scale.  The Brazillian Guarani tribe give their name to the plant.
