Seeds of Podocarpus lambertii Kl. were collected from a native forest, at the Vista Alegre farm in São Sepé - RS. Physiological maturation was evaluated. For the study of the  physiological  maturation,  seeds  were  weekly  cropped from the moment that they became  developed  and  consistent, until their total fall. The seeds were then analysed according to their moisture content, oven-dry weight and germination percentage.The results  indicated  that  the  physiological  maturation  of  the  seeds  occurs when the humidity percentage  reachs  lower  rates (32%)  and the dry weight rates (17,68 g/100 seeds). Also that the humidity percentage  may  be  considered  as  the  best  parameter  to  determine  the  physiological  maturation  of Podocarpus lambertii Kl. seeds.
