Diversidad de helechos y licófitas de la Reserva Natural Punta Lara, Buenos Aires, Argentina

Punta Lara Natural Reserve shelters the relict of the Southernmost riparian forest in the world, where the flora is threatened by the anthropic expansion and by the introduction of exotic species. In this area the ferns and lycophytes grow in particular environments as marshland, grassland and margi...
