Oil. — Yield very small, only 3£ oz. from 534 lbs. of leaves, in fact 

 too small to make a fractional distillation. It has thus the 

 smallest yield of the stringy-barks next to E. capitellata (H. G. 



Smith). 



Eucalyptus lactea, sp.nov. 



" Spotted Gum." 



(Plate xlvi., fig. 5.) 



A fair-sized tree with a dirty, flaky bark, which occasionally is 

 smooth. 



Sucker leaves ovate; leaves of mature trees lanceolate, up 

 to 6 inches long and varying in breadth up to 9 lines, straight 

 or falcate, not shining, of the same shade of green on both sides ; 

 petiole under 1 inch. Venation fairly well marked, veins oblique, 

 spreading, the distinct intramarginal vein removed from the edge. 

 Oil clots numerous. 



Peduncles axillary, with few flowers (5 to 7) in the head, 

 occasionally only 3. Cabyx hemispherical. Operculum hemi- 

 spherical, shortly acuminate. Ovary flat-topped. Stamens all 

 fertile; anthers parallel, opening by longitudinal slits. 



Fruits hemispherical to oblong; rim with valves domed and 

 almust touching, thus leaving only a slight aperture to the ovary; 

 or the rim thin and the valves exserted and widely distended. 



Hob.— Mount Vincent, Ilford (R. T. Baker); Oberon Road, 

 O'Connell (R. T. Baker, R. H. Cambage) ; Southei'n Road, 

 Wingello (R. T. Baker, H. G. Smith); along the main Western 

 Road, Blackheath and Mt. Victoria (R. T. Baker). 



In the tield this tree might be confounded with E. viminalisov 

 E. ha mastorna, as both these Eucalypts have a similar although 

 variable bark. 



The bark of this species, however, never has the horizontal 

 "scribble" insect markings almost invariably occurring on E. 

 rimii /nit's, Labill., and E. hcemastoma. It has similarly shaped 

 leaves in all its stages of growth, whilst the sucker-leaves of E. 

 viminalis are narrow, cordate-lanceolate, sessile.
