- Diagnosis
- Trees (?) distinct in the wood structure with abietoid pitting of tracheids and doliostroboid (not bordered) pits in the cross field of branch wood, and lacking ray tracheids as well as resin channels. Foliage shoots bearing polymorphic, helically arranged needle leaves – longer acicular to falcate and shorter appressed. Seed cones similar to those of Agathis (Araucariaceae) disintegrating at maturity into individual scales; cone scales flat, widely obtrullate to obovate in the outline, apparently simple, with several longitudinal ridges corresponding to resin ducts, typically with an apical spiny process; seeds free, inverse, one per scale (aberrantly two), with one large basal or basal-lateral wing and occasionally with an additional opposite ± smaller wing. Pollen of the Araucariacites type.
