PLATE LXX. 



A transverse section of the leaf of this Iroubnrk rut through the mid-rib. Mn<t 

 Ironbarks give a low yield of oil, and this species is no exception. The coriaceous 

 character of the leaf is marked bv the compact palisade parenchyma, and 

 limited spongv ti^-ue. The supporting tissue to the mid-rib is seen to be 

 restricted, but the woody fibres (red) almost form a complete circle around 

 the bundle, which is birol'lateral. On the right of the central vascular bundle is 

 seen an apparent lignification of the palisade tissue, due most probably to 

 pathological aftection. x 60.
