- Diagnosis
- Pith small, homogeneous, heterocellular with
variable diameter parenchyma cells. Primary xylem endarch. Tracheids
in primary xylem with annular and helical thickening. Secondary xylem
homoxylic, with growth rings. Radial pitting, uniseriate, contiguous and
flattened; rarely biseriate, alternate. Xylem rays uniseriate, homogeneous,
low (1–7 cells high). Cross-fields with 1, rarely 2, rectangular
to oblique oval, partially circular, simple, sometimes slightly areolate
pits. Vertical parenchyma cells and secretory cells absent.
