- Diagnosis
- Heteroxylous semi-ring-porous wood with distinct growth ring boundaries. Vessels are solitary or in radial multiples of 2–5, and can exceed 300 μm in tangential diameter, perforation plates are exclusively simple, tyloses abundant. Rays are 1–5-seriate and heterocellular with body composed of procumbent cells and 1–4 marginal rows of upright cells. Axial parenchyma is reticulate with numerous prismatic crystals both in chambered cells and idioblasts, forming long (up to 12 cells high) vertical chains.
