2. With E. exserta F.v.M. 



I already drew attention to these species in Proc. Linn. Soc. N.S.W. xxix, 774 

 (1904), and while I think that this is the species closely related to E. Monisii, the latter 

 should be kept separate. Under E. exserta I have drawn attention to the rim in this 

 species (ante p. 33 footnote) and have noted that it is capsular, and is not a part of 

 the calyx-tube. That of E. Monisii is an exaggerated example of what we see in 

 E. exserta, and figure 6c, Plate 135, and figure 7a, Plate 132, may be compared. While 

 the rim and the valves are structurally portion of the capsule in both cases, in the case 

 of E. exserta there is greater demarcation between them than is ordinarily the case in 

 E. Morrisii. In some smaller fruited specimens of E. Morrisii the demarcation is as 

 marked as in E. exserta. 



The two species have brown, not red timbers, and both roughish bark, that of 

 E. exserta being the rougher. 



While they have both narrow juvenile foliage, that of E. Morrisii is more rigid 

 than that of E. exserta, indeed rigidity is a proper word to apply to the habit of the 

 former species, and flexibility to the latter. The difference in size of the two species 

 is not as great as was at one time supposed, and their relations are interesting. 



3. With E. santalifolia F.v.M. 



" The buds, especially the operculum, resemble those of E. santalifolia F.v.M., from which specieB, 

 however, the venation of leaves, and mature fruits differentiate it." (R. T. Baker.) 



The reference is really to E. pachyloma Benth., and having studied this species 

 in the field in Western Australia since my references to it in Part VII of the present 

 work, I will postpone comparison of that remarkable rimmed species with E. Morrisii 

 until I separately deal with E. pachyloma. 



4. With E. viridis R. T. Baker. 



"Mr. W. Baeuerlen, who was the first to collect E. Morrisii, states :— " This species, also a Mallee, 

 grows in the same way as and associated with Green Mallee, E. viridis R.T.B. ; but the leaves are so different 

 in colour, &c, as to distinguish it at once. The bark is much the same, but persistent often right out to 

 the branches ; at other times smooth nearly half-way down. The persistent bark is rougher and more 

 furrowed, in the larger trees, making a sUght approach to the Ironbarks. In the crosscut it is red or 

 brown, quite different from E. viridis R.T.B., and the buds, flowers, and fruit are totally different.'' 

 (R. T. Baker.) 



5. With E. viminalis Labill. 



" The expanded valves are similar to those of E. viminalis, but this is its only 

 connecting link with that species " (R. T. Baker), but under " Timber," spoken of as 

 " E. viminalis and E. tereticornis, its allies." 



E. viminalis is a large white or Ribbony Gum with pale, soft timber and a denizen 

 of river banks and swampy places in cold localities, a direct contrast to E. Morrisii 

 in all these respects.
