- Diagnosis
- Pith medium to large, solid and heterocellular, with sclereids.
Inner parenchyma cells larger surrounded by a sheath of long
narrow parenchyma cells. Some isolated sclereids between the sheath
and the primary xylem. Primary xylem endarch. Secondary xylem
homoxylic, with growth rings. Araucarian radial pitting, uniseriate
to biseriate, rarely triseriate. Xylem rays with abietinoid pitting,
uniseriate to partly biseriate, high (1–28 cells high). Araucarioid
cross-fields showing up to five large and unordered oculipores.
