Cycas silvestris

A tall Cycas from coastal lowlands of eastern Cape York Peninsula, Queensland, named for its forest habitat. It grows in a hot monsoonal climate with a very wet summer and a long dry winter, so it wants warmth all year, bright light and generous water in summer with drier conditions in winter.
