Pampas
properly treeless pasture land covered with grass, but used more comprehensively for the whole table-land of South America, from the boundary of Brazil, where the regular seasons of the tropics cease, across the states of La Plata and Patagonia nearly to Cape Horn. It may be divided into three botanical zones: the Interior Northwestern Chanar-steppe, the True Pampas, and the Southern Plains of Patagonia.
PAMPAS GRASS (Gynerium argenteum), a grass which grows in the pampas in the S. parts of South America. It has been introduced into Europe as an ornamental plant.
