As regards Queensland localities, the late Rev. B. Scortechini remarks 

 (Proc. Linn. S'oc. N.S.W., viii, 248), " I found it growing in wet places not far off 

 the hanks of Nerang Creek. Since then Mr. P. M. Bailev and I found it at Strad- 

 broke Island, close to Dunwich. Afterwards I followed its course to the Brisbane 

 River, and as far inland as Brown Plains, not far away from the Logan. In all 

 instances this gum-tree was found growing on wet marshy ground, having for its 

 companion Melaleuca leucadendron Linn. Whether this tree crosses over to the 

 north side of the Brisbane River remains to be proved by further investigation."

AFFINITIES. 



1. With E. resinifera Sm. 



E. robust a resembles in some respects K. resinifera, but the leaves are generally broader, of a 

 lighter color above and more .shining beneath, their veins are more prominent, not almost horizontally 

 spreading, nor is the intra-mirginal vein nearly contiguous with the edge; the flowers are larger, the tube 

 of the flowering calyx is longer and more bellshaped, the lid more turgid beneath, the fruit considerably 

 longer, the valves are enclosed, convergent and remaining often connected at their summit, while the fruit- 

 rim is thinner and surrounded by a narrower ring. However, the variety pellita of E. resinifera has the 

 large flowers and broad leaves of E. robusta, but the proportionately short fruit with exserted and mostly 

 free, erect and acute valves of the former. (" Eucalyptographia " under E. robusta.) 



I do not think that the affinities arc close. E. robusta is a coast-loving 

 species; E. resinifera ascends the coast range. The former has a softish, almost 

 scaly bark ; the latter is a larger tree with almost stringy bark ; the buds and fruits 

 of the two species are very dissimilar, and those of the former are, like the leaves, 

 coarser than those of the latter species. Both yield red timbers not very dissimilar 

 in general appearance ; that of the former being called " Swamp Mahogany," and 

 that of the latter " Red or Porest Mahogany." 



2. With E. saligna Sm. 



From E. saligna. which comes in most of its characteristics near to E. bolryoides and E. resinifera, 

 we can distinguish E. robusta already by the persistency of the bark of the latter. ("Eucalyptographia" 

 under E, robusta.)
