Type

Original diagnosis/description

Growth rings boundaries are indistinct, with earlywood zone significantly wider than latewood. Earlywood tracheids are characterized by scalariform pitting. Latewood tracheid pitting on radial walls is araucarian. Cross-fields pits are araucarioid to podocarpoid. Tangential and horizontal walls of ray parenchyma cells have both distinct pitting (Abietineentüpfelung sensu Kräusel). Axial parenchyma and resin canals are absent. Rays are exclusively uniseriate.

Etymology

Named for the friend and head of the geological part of the Czech Antarctic project Petr Mixa; the name also points to a “mixed” character of features, situated between Sahnioxylon Bose & Sah and Phoroxylon Sze.
