 New South Wales 43:747-749. PI. 75. 1918.— Eucalyptus Marsdeni, forma vel sp. nov. is 

 described in regard to its seedling, juvenile, and mature leaves; inflorescence; fruit; bark 

 (unusual for a Eucalypt, to be classed with the stringy-barks, yet laminated with a sort of 

 ochreous deposit on the outer surface of each layer, branch bark smooth and greyish, a half 

 bark); timber, which is light brown, straight grained, has few gum-veins and works well, 

 resembling E. viminalis in physical characters. The only known tree has been cut. The oil 

 from leaves and terminal branches is thick and viscous, and its characteristics are discussed 

 in detail. — Eloise Gerry.
