Original diagnosis/description

Secondary pycnoxylic wood. Abietinean type pitting in the radial walls of tracheids. Some ends of tracheids in radial section irregular, bent or overlapping each other. Rays uniseriate. Vertical and horizontal walls of ray parenchyma cells smooth (unpitted). In the earlywood, cross‐field pitting of araucarioid type; in latewood, cross‐field pitting of cupressoid type. Axial parenchyma present, some parenchyma cells with druses in idioblasts.

Etymology

The genus is a combination of Austro, which refers to the south, Ginkgo, after the living genus, and ‐xylon, referring to wood.
