266 ON SOME N.S.W. TAN-SUBSTANCES. 



Leaves scattered, sickle-shaped lanceolar, not very long, rather 

 more shining above than below ; their lateral veins very subtle and 

 numerous, usually more erect than transverse, the circumferential 

 vein somewhat removed from the margin of the leaf ; oil-dots 

 copious, more or less pellucid. (Eucalyptographia). 



Leaves from ovate-lanceolate and very oblique to lanceolate and 

 nearly straight, rarely above 1 inch long, rather thick and rigid, 

 the veins very oblique, almost as in E. obliqua, but usually fine 

 and less conspicuous, and more numerous, especially in the 

 narrower leaves. (B. Fl.) 



Average length 154*8 mm., average breadth 30*2 mm. Colour 

 of powdered leaves, olive-brown with a slight tinge of blue. 



Extract. — They yield 34-08 per cent, to water at 100° C. Colour 

 of extract ruby, but lighter than E. stellulata ; of moist residue, 

 brown. 



Kino-tannic acid — 12*59 per cent.
