complex. Vascular trace to bract-scale complexes cylindrical at base, then divided
into many free bundles arranged in reniform with abaxial invagination. Resin canals
in cortex of cone axis, in abaxial and adaxial tissue of bract-scale complexes, in
abaxial tissue of scale region and in bristle-like projection. Fairly abundant fibers in
