On the Structure and Identification of Eucalyptus Species

The wood structure of nine species of Eucalyptus have been studied in detail both under light and scanning electron microscope. They have been distinguished on the basis of various anatomical characters viz. vessel and parenchyma distribution, presence or absence of crystals in parenchyma and percentage of tri-seriate rays, and vestured pit morphology. Though microscopic features do help to some extent in the identification, ultrastrncture of vestured pits of vessels aod fibres have been found more useful in distinguishing different species studied.
