Leaves scattered, elongate or sickleshaped-lanceolar, rarely 

 verging into an almost oval form, equally green on both sides, 

 with very subtle much concealed oil-dots ; their lateral veins 

 moderately spreading, the intramarginal vein distinctly removed 

 from the edge. (Eucalyptographia.)

 inches long, the lower ones broader, thick and coriaceous, the 

 very oblique rather distant veins prominent. (B. Fl.) 



Average length 91 -8 mm., average breadth 35-5 mm. They yield 

 a powder of a Brunswick green colour, On account of the large 

 quantity of oil they contain they clog the mill a good deal. 



Extract.— They yield 40*18 per cent, to water at 100° C. 

 Colour of extract same as that of E. amygdalina (Nelligen), with 

 yellow deposit on cooling ; and of moist residue light olive-brown 



Kino-tannic acid — 10*13 per cent.
