- Diagnosis
- Coniferous wood with distinct annual rings and vertical and horizontal resin canals. Bordered pits on the radial walls of the spring tracheids, in one row.
more rarely in two rows; tangential pits very scarce. Medullary rays fusiform, with resin ducts, or linear; of the latter, a small percentage is biseriate. Parenchyma of the medullary rays with abietinean pits; tracheidal elements constantly present, but few. Epithelial lining of the resin canals thick-walled. Wood parenchyma present along the periphery of the annual rings. Pith consisting of thick-walled, short cells with numerous pits and rounded or angular in outline. Protoxylem with spiral tracheids. Leaf traces numerous,
containing the same kind of tracheids. Cortex with layers of stone cells.
