Araucariaceae: Known for massive seed cones and species such as the dammars and Araucaria.1
Sciadopityaceae: Represented by the umbrella pine (Sciadopitys verticillata), which is endemic to Japan.1
Cupressaceae: A diverse family that includes cypresses, redwoods, and junipers.1
Podocarpaceae: A large family characterized by modified, fleshy scales on their seed cones.1
Cephalotaxaceae: A small family found in East Asia, often referred to as plum-yews.1
Taxaceae: Includes yews; these are sometimes placed in their own order due to their unique reproductive structures, which lack typical seed cones.1
