- Diagnosis
- Central pith is not distinguished. Growth rings are absent. Vessels are of medium sized, solitary, few are radial multiple of two to five. Vessel having tangential diameter 100–180 μm, radial diameter 90–160 μm. Their boundary walls are thick. Vessel frequency 12–15 per square mm. Rays are contiguous with vessels. Perforation plates are oblique and simple. Intervascular pit pairs opposite, bordered and polygonal. Pit pores are oval in shape. Xylem parenchyma cells are thin walled, paratracheal, vasicentric and one layer around the vessel. Xylem rays are heterogenous and are bi– to multiseriate. Biseriate rays are of 16 to 25 cells in height and 40–50 μm in diameter. Multiseriate rays are 24 to 40 cells in height and 90–120 μm in diameter. Frequency of xylem ray is 8 to 10 per square mm. Narrow rays are comparatively abundant than broad rays. Both narrow and broad rays are intermingled with each other. Wood fibres are non–septate, few are septate and storied, elongated, square to hexagonal, 250–560 μm in length, 40–50 μm in diameter.
