- Coniferous plant with Brachyphyllum- to Pagiophyllum-type leaves. Leafy shoots branching at acute angles in one plane, leaves helically arranged. Ovuliferous cones lax. Ovuliferous scales stalked, trilobate, with lobes in one plane, two lateral, oval in shape, bearing one ovule each, and sterile reduced lobe (lobes) situated between them. Ovules oval in outline, with micropylar beak directed basipetally. Bract small, leaf-like, merged with ovule-bearing scale stalk in part. Polliniferous cones simple, oval in outline, born at the end of the leafy twigs. Microsporophylls helically arranged, consisting of a stalk and a distal free blade. Pollen sacs attached in awhorl around themicrosporophyll stalk. Pollen grains circular in polar view to oval in equatorial or oblique view. Exine surface rugulate (folded irregularly). Surface of folds smooth.
