ON SOME N.S.W. TAN-SUBSTANCES. 263 



Vernacular Name — ■" Ribbon Gum." 



Locality whence this particular specimen was obtained — 



Nelligen, Clyde River. 

 Geological Formation — Granite. 

 Part of the Tree Examined — Leaves. 

 Particulars of the trees whence they were obtained — Height 



100 to 120 feet, diameter 2£ feet. 

 Collected 21st September, 1886. Analysed 24th October to 



24th November, 1887. 



Leaves on rather short stalks, scattered or rarely opposite, 

 narrow- or sickle-shapecl-lanceolar or very narrow, usually 

 attenuated into an acute but oblique base, generally not of thick 

 consistence, mostly of a saturated green and somewhat shining on 

 both sides ; lateral veins very thin, not much spreading, nor closely 

 approximated, the circumferential vein remote from the edge of 

 the leaf ; oil-dots very copious transparent. (Eucalyptographia.) 



Leaves from linear to broadly lanceolate, straight or falcate, 

 mostly acuminate and 2 to 4 inches long, when narrow rather 

 thin, when broad thicker, the veins few and oblique but often 

 inconspicuous, the intra-marginal one at a distance from the edge, 

 or rarely near to it. (B. Fl.) 



These leaves are tapering linear, slightly falcate, very thin, and 

 with very prominent midrid. Many of them are slightly spotted 

 through insect punctures. Oil dots inconspicuous. 



Average length 127 '8 mm., average breadth 10 - 6 mm. They 

 yield an olive-brown powder. 



Extract. — Yield 32*13 per cent, to water at 100° C. Colour 

 of extract dark lemon, of moist residue, brown. 



Kino-tannic acid — 1*815 per cent. 



For a note on leather made from the leaves of the same species 

 see p. 255. 



The collector observed, " the leaves of this species ought to be 

 rich in oil," before he knew the species. They are very fragrant 

 yet. This species yields much of the " Eucalyptus globulus " oil 

 of commerce ; the specific name globulus adherring to ninety-nine 

 hundredths of the Eucalyptus oil sold, in defiance of botanical 

 science.
