- Diagnosis
- Growth rings absent. Wood diffuse-porous. Vessels moderately few, 17-24 (mean 20) per square mm; mostly solitary (93%) and rarely in radial pairs ; round to oval in cross section; 40-85 (mean 68) x 70-130 (mean104) pm in tangential x radial diameter; 390-660 (mean 495) Jlm in vessel element length; perforation plates exclusively simple; intervessel pits alternate, round
to elliptical (5 Jlm in diameter); vessel-ray pits simple, variously shaped (10 pm in diameter). Imperforate tracheary elements fiber-tracheids with small bordered pits. Axial parenchyma vasicentric, no crystalliferous elements observed. Rays predominantly uniseriate, and sometimes biseriate (35 um wide); 240 um-1.3 mm high; nearly homocellular, occasionally with 1 to 2 marginal rows of upright or square cells ; procumbent cells 40 x 25 jim in radiallength x height; upright cells 30 x 50 um in radiallength x height ; no crystalliferous elements observed.
