Among plants of Venezuela, over 25,000 species of orchids are found in the country's cloud forest and lowland rainforest ecosystems. These include the "flor de mayo" orchid ("Cattleya mossiae"), the national flower. Venezuela's national tree is the araguaney, whose characteristic lushness after the rainy season led novelist Rómulo Gallegos to name it ""a primavera de oro de los araguaneyes"" (the golden spring of the araguaneyes). The tops of the tepuis are also home to several carnivorous plants including the marsh pitcher plant, Heliamphora, and the insectivorous bromeliad, Brocchinia reducta.
