" A fairly common tree in the Rockhampton district, growing usually in moist, 

 though not necessarily in swampy places. Large smooth-barked trees, having a pendulous 

 habit, with large poplar-like leaves. Timber soft, red (when newly cut. — J.H.M.) in 

 colour, useless except for firewood, even this of poor quality." Yeppoon (J. L. 

 Boorman). 



Thirty-eight miles west of Mackay, Pioneer River, and tree common about 

 Mackay. The young leaves when dry were 12 inches long by 11 inches broad. " On 

 full grown tree the leaves are much smaller, and roundish in shape." (Sid. W. Jackson.) 



Port Denison or Bowen (Dallachy) ; Pandanus Creek (E. B. Yearwood). 



" Many buds have double operculum when collected." Townsville (R. H. 

 Cambage, No. 3,801) ; Reid River, near Townsville (N. Daley). 



"Poplar Gum," near Atherton and throughout the north. "Low stunted tree, 

 spreading gnarled branches, white bark, timber grey, very gnarled grain." (H. W. 

 Mocatta, District Forest Inspector.) 



Atherton (E. Betche). These specimens (in bud) are in no way different from 

 those of E. pastoralis. 



Ten Mile, Stannary Hills (R. G. Shearer). 



The following localities, not already enumerated, given in B.FL iii, 243, may bo 

 taken in here : — 



Fertile pastures on the Burdekin {Mueller), Percy Island (A. Cunningham), 

 Broad Sound (Filzroy), Bowen River [Bowman). 



AFFINITIES. 



Mueller (" Eucalyptographia " under E. alba) compares this species only with 

 E. platyphylla F.v.M., a species he later suppresses as synonymous with E. alba. It 

 is not an easy species to suggest affinities for. It is a White Gum, and its affinities are 

 most probably to be found amongst other White Gums. 



1. With E. oligantha Schauer. 



In leaf E. alba has some resemblance to this species. See Plate 64 of the present 

 work. The anthers are, however, different, and probably the fruit, only at present 

 known, as regards E. oligantha, in the young state. 



E. oligantha is still imperfectly known. 



2. With E. Mooreana (W. V. Fitzgerald) Maiden. 



The two species were thus compared in Proc. Roy. Soc. N.S.W. xlvii, 223. 



" The fruits have something in common, and also the juvenile leaves, which are, 

 however, petiolate in E. alba. The buds are very different. The mature leaves of 

 E. alba are never so lanceolate as those of E. Mooreana. E. alba is a glabrous, soft, largo 

 gum of moist flats, E. Mooreana is a crooked glaucous tree of mountain tops." 



I am further investigating the affinities of E. alba, and will report later,
