It is confined to New South Wales, and so far it has 'only been recorded for a 

 very limited area in the Western Plains. This may be defined as the triangular area 

 made by the Bourke and Cobar lines which junction at Nyngan. The third side of 

 the triangle joins Cobar with Coolabah, or rather the shape is a quadrilateral, as it 

 must join a point 38 miles north of Cobar. 



Following are the specimens represented in the National Herbarium of New 

 South Wales :- 



" Grey or Black Mallee." Girilambone (W. Baeuerlen). The type. 



" A low growing tree with a wide-spreading habit. It is not strictly speaking 

 a Mallee. (I would call it a Mallee, although it attains an unusual size, J.H.M.). It 

 seldom attains more than 20 feet high : it is often much less. The bark is ribbony, of 

 a thick texture, falling away in flakes, which are of a blackish colour ; the ends of the 

 branches are rough," Girilambone (J. L. Boorman). Juvenile foliage narrowish. 

 Young and adult foliage lustreless. Girilambone Hill (J.H.M. and J. L. Boorman). 



" Narrowish juvenile foliage. Mostly a tall Mallee, but seen up to 30 or 35 feet, 

 with a hard, black, flat-fissured bark, up to the ultimate branchlets. One foot in 

 diameter up to 1 ft. 9 in." Coolabah (J.H.M.) 



" Bark rough to tips." Mount Boppy (J. L. Boorman). 



Cobar (correspondent of Bev. Dr. Woolls prior to January, 1887). Thirty-eight 

 miles north of Cobar (R. H. Camhage). Some fruits smaller and with flatter rims 

 aff. E. exserta F.v.M. 



AFFINITIES. 



l. With E. tereticornis Sm. 



" Perhaps the roost remarkable specific character about it is the rim of the fruits. The word 

 " domed " hardly expresses correctly this feature, for merging into the valves at the top it forms as it were 

 a truncate cone resting on the hemispherical calyx base. This conformation of the rim is noticeable as 

 soon as the stamens begin to fall off, and from this stage until and after its full development, it gives 

 the appearance to the fruit of a pathological affection or a monstrosity. The shape of the fruits, however, 

 is remarkably constant throughout the extensive (sic) range of the species. It is, so to speak, the rim of 

 E. tereticornis Sm., only very much more emphasised. 



" Thi3 Eucalypt differs, however, from that species in the venation and texture of its leaves, shape of 

 operculum, chemical constituents of its oil, as well as in the timber and bark. In botanical sequence it is 

 placed next to E. tereticornis Sm." (E. T. Baker.) 



Its narrow juvenile leaves, and its brown timber sharply separate it from 



E. tereticornis. Its affinity is with E. exserta F.v.M.
