Two new records as well as material to confirm two non-vouchered records were collected by colleagues at the Instituto Darwinion and Parques Nacionales during botanic expeditions to Misiones in northeastern Argentina. Misiones is a strip of land between the Uruguay and Parana rivers, with lon- gitudinal mountains reaching approximately 800 m in elevation. This region is under exploration in order to study and document the floristic composition of the southernmost subtropical forests in South America. These records are elements of the Araucaria angustifolia forests and rocky "campos", two pri- mary communities that should be maintained and preserved within national and state reserves.
