- Diagnosis
- Diffuse porous dicotyledonous wood, no growth rings, wood consists of vessels, parenchyma, wood Fibers and wood rays. Vessels solitary, in multiples of 4, vessels circular to sub circular and Perforation plates are simple and oblique. Alternate bordered pits. Tyloses present. Parenchyma is paratracheal vasicentric. Fibers are aseptate and non-storied. Wood rays
mostly Rays are uni-bi-tri-seriate and homogeneous. Wood dicotyledonous, diffuse porous, pith not seen, vessels mostly solitary, in multiples of four .Vessel frequency 16 to 19 per sq. mm. Vessels are medium sized and can be seen with the naked eyes. Obliquely 15 µ x 21 µ., rays are seen contiguous with the vessels. Vessel members are long and measure 225 x 21 µ. Perforation plates are simple and oblique. The intravascular pit pairs are simple, alternate bordered and hexagonal. Pit pores are oval in shape. Tyloses present. The xylem parenchyma are paratracheal, vasicentric and in one layer around the vessels. Xylem rays are not seen with the naked eyes.
The rays are heterogeneous, in composition, divisible into two types on the basis of size and their composition.
