The Podocarpaceae are a large family of mainly Southern Hemisphere conifers, comprising about 156 species of evergreen trees and shrubs. It contains 19 genera if Phyllocladus is included and if Manoao and Sundacarpus are recognized. Parasitaxus usta is unique as the only known parasitic gymnosperm. It occurs on New Caledonia, where it is parasitic on another member of the Podocarpaceae, Falcatifolium taxoides. The genus Phyllocladus is sister to Podocarpaceae sensu stricto. It is treated by some botanists in its own family Phyllocladaceae.
