- Diagnosis
- Diffuse porous wood; solitary vessels, in radial multiples
and rarely in clusters, mean tangential diameter of <100 mm;
simple and scalariform perforation plates; alternate and subopposite
intervessel pits; vessel-ray parenchyma pits with
distinct borders, similar to intervessel pits; non-septate and septate
fibers; vasicentric, aliform to confluent axial parenchyma; 1-2
seriate rays, homocellular to weakly heterocellular, idioblastic
secretory cells (“oil or mucilage cells”) common in ray parenchyma
and among the fibers.
