It is sometimes called White Gum; at the same time it should be borne in mind 

 that it is always blotched, and sometimes has rough bark up to 20 feet from the ground. 

 The upper part of the trunk and the limbs are smooth. The sap-wood is very thin, 

 and the timber is red. The foliage is dull. 



I do not find the mature leaves with the intramarginal vein so far removed from 

 the edge as in the drawings of the type; in all the specimens accessible to me (and I 

 have an excellent series) they are quite close to the edge. 



RANGE. 



No type is quoted for this species, but the following are New South Wales local- 

 ities :— Dubbo to the Darling River ("Gum," W. Baeuerlen); Nymagee, Condobolin 

 ("Coolabah"); Mt. Hope ("Yellow Jacket" and "Gum"); Cobar (" Coolabah 

 Gum"); Drysdale ("Coolabah"); Bobadah, 30 miles east of Nymagee, one of the 

 most easterly localities for the species. 



I proceed to show that, in addition to New South Wales, it extends to South 

 Australia and the Northern Territory, and also to Western Australia. It is a denizen 

 of regions of low rainfall, and its recorded range may be roughly defined as central 

 interior New South Wales as far east as Dubbo and Condobolin. It does not appear 

 to have been collected west of the Darling, though that is only a matter of time. Then, 

 in South Australia it occurs from the Murray to well into the Northern Territory. 

 Coming south again, the Elder Expedition collected it in the Cavenagh Range, ad- 

 jacent to South Australian localities. As it has. been confused with other species 

 (principally E. bicolor A. Cunn.) I confidently expect that many new localities for it 

 will be ascertained, now that we know more about it.

 given to me by Mr. Baker as fairly representing the species. 



"Coolabah," Wilgaroon, 50 miles south of Bourke (R. H. Cambage); Byrock 

 (J. L. Boorman); Coolabah (R. N. Peacock, J. L. Boorman, H. Kelly, J.H.M.). Tree

 stems are of a scaly nature, with a yellowish cast on the permanent bark, the whole 

 tree generally being of a silvery lustre. Clean stems, without branches, for a consider- 

 able distance from the ground. Reminds me of E. melliodora somewhat." Narrow
