as beiii<r worthless for .splittintr ; possibly the value put on the tree 

 by woodmen around Pllthani may be due to the dryness of the soil 

 in that district. 



Conclusion. 



The composition of the oils and their physical constants, as tabulated, 

 are not matched by the oil of any of those species examined by Baker 

 and Smith that could possibly be regarded as similar to the Yertchuk. 

 Hence from morphological characters of the buds, carpels, leaves, 

 seedlings and bark, as well as from the characteristic oil distilled 

 from the foliage, it is evident that these trees in the valley of the 

 lower Yarra can only be included in the species E. Consideniana ; 

 for although they show considerable variations among themselves, 

 they diverge still further from any other known species. 



Mr. J. IJ. Maiden lias included a very careful review of this species 

 in his Critical Revision of tlie Eucalypts (Vol. I., p. 312), with 

 accurate hgures of the forms found in New South Wales, but for the 

 reasons given we would venture to amend and amplify his descrip- 

 tion of the species, indicating our own alterations and additions 

 by means of italics. 



Description. 



A tree of medium height, varying frjmi 20 to 60 feet. 



Bark. — Fibrous, resembling Eucalyptus ohliqua, but softer, grey 

 in colour on the outside, and reddish inside, {in-iier Ixtrk ye/loirisli, 

 like E. Muelleriana. ). Persisting up the trunk and main branches. 

 Sniull branches smooth ; hrancJilets a/iyu/ar. 



Juvenile Leaves. — Seedlings: Leaves opposite, narrow-lanceolate, 

 soon' becoming ovate and ovate-lanceolate to broad ovate-lanceolate, 

 and acuminate ; smooth or rough, sessile and petiolate, varying from 

 one inch to three inches in length, and one half-inch and more in 

 breadth, grey-green or sap-green in colour. Margins entire 

 or undulate luith sinall tuffs of stellate hairs, stems reddish, warty 

 glandular, ultimately smooth. 



Epicormic Shoots. — Leaves opposite, shortly petiolate, obtuse, ovate 

 t'o broad ovate-acuminate, slightly oblique and falcate, and lanceolar- 

 acuminate, often nearly straight, hecomnig alter narc with longer 

 petioles.
