It attains not its greatest height, but certainly its greatest 

 diameter, on the highest hills amongst the roughest and rockiest 

 parts (W. Bauerlen). 



Perhaps the most 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 range of the species- 

 It is, so to speak, the rim of E. tereticornis, Sm., only very much 

 more emphasised. 



This Eucalypt differs, however, from that species in the vena- 

 tion and texture of its leaves, shape of operculum, chemical con- 

 stituents of its oil, as well as in the timber and bark. 



The expanded valves are similar to those of E. viminalis, but 

 this is its only connecting link with that species. 



The buds, especially the operculum, resemble those of E. san- 

 talifolia, from which species, however, the venation of leaves, 

 and mature fruits differentiate it. 



In botanical sequence it is placed next to E. tereticornis, >Sm. 



It is a remarkably constant and well-defined species throughout 

 the area of its distribution. 



It is named after R. N. Morris, LL.D., the present Superin- 

 tendent of Technical Education in New South Wales, in 

 acknowledgment of his co-operation in our work on the economics 

 of the genus Eucalyptus. 



Timber. — A hard, close-grained, interlocked, brownish-coloured, 

 durable timber, quite distinct from that of E. viminalis, Labill., 

 and E. tereticornis, Sm., its allies. 



Oil. — Leaves sent from Girilambone, New South Wales, loth 

 January, 1900. Average yield of oil from three distillations, 

 1 -69 per cent. The crude oil is but little coloured, and has an odour
