Neotropis – Pampean

Pampean covers mainly part of Argentina (from north of the country to the basin of river Negro, which is including), further Uruguay and small south of Brasilia. This area is botanically poorer; it has small number of endemic genera and more endemic species. Pampean is formed also by the influence of Paleotropis, the rest of Neotropis and also by the Antarctis a bit.
