AFFINITIES. 



"With E. saligna Sm. 



E. grandis is often called " Flooded Gum," and it is a pity that the name cannot 

 be reserved for it. At the same time, it is often called " Blue Gum " (a name I should 

 like to see reserved to E. saligna) by experienced people, while normal E. saligna is often 

 more or less glaucous. The fruits have often a slightly urceolate shape, and sharp, 

 indexed valve-tips. As a rule, though not invariably so, the buds and fruits are 

 slightly larger than those of E. saligna. 



It is because of the confusion of vernacular names, that the timbers of E. grandis 

 and E. saligna are still more frecpiently confused than they should be. As compared 

 with E. saligna, the timber of E. grandis is slightly paler in colour, lighter in weight 

 (it floats in water when dry), shrinks more, is tougher, is not so durable, and is, therefore, 

 chiefly used for inside purposes in preference to such uses as fence-posts. Both are 

 shaft-like Gums, attaining great development in sheltered, deep-soil, well-watered 

 valleys. 



Explanation of Plates (164-167). 



PLATE 164. 

 • E. terminalis F.v.M. 



la. Juvenile leaf; 16, mature leaf; lc, fruits. Darwin, Northern Territory. (H. I. Jensen and G. F. 



Hill, No. 398.) It is probable that these specimens are very near the type. Note in la the 



hairiness, the triplinerved venation, and in lc, the long fruit. 

 2. Scurfy buds. Darwin. (N. Holtze, seen by Mueller.) Probably very near the type. 

 3a. Umbel of flowers, with scurfy calyx-tubes; 36, front and back views of anthers. Darwin. (G. F. 



Hill. No. 343.) Probably very near the type. 

 4a. Mature leaf ; 46 and 4c, fruits, the latter with thick rim. Darwin. (G. F. Hill, No. 425.) Mr. Hill 



points out that he sees no difference between his 398 and 425, and they are probably very near the 



type. 

 ha. Smaller mature leaf ; 56, fruits with thick rim. There is a thick rim also in 4c, and indeed it is common 



in the species. Darwin. (Collector of Mueller, 1890.) Probably very near the.type. 



6. Fruit. Pine and Horseshoe Creeks, near Darwin. (E. J. Dunn.) 



7. Fruit. Bathurst Island, Northern Territory. (G. F. Hill, No. 470.) 



8a. Mature leaf; 86, buds; 8c and M, fruits. Goody Goody, near Derby, North- West Australia. 



(W. V. Fitzgerald, No. 301.) 

 9. Rather squat, not quite mature fruit. (We have a cimilar shape, No. 13, from Emerald, Queensland.) 

 Base of Mount House, Kimberleyc, North- West Australia. (W. V. Fitzgerald No. 970.) 

 10a. Mature leaf; 106, unripe buds. Palmer River, North Queensland. (Dr. W. E. Roth.) 

 11. Unripe buds. Rockhampton, Queensland. (J.H.M.) 



12a. Broad, intermediate or nearly mature leaf; 126 and 12c, fruits. North Rockhampton. (Andrew 

 Murphy.) 



13. Immature fruit, spotted and scurfy, almost fleshy. Compare No. 9. Emerald, Queensland. (J. L. 



Boorman.) 



14. Fruit. Gadwall, Alpha, Queensland. (G. T. Wood )
