570 ON EUCALYPTUS GU^NII, HOOK. F., 



name has taken place in Europe in a number of well known 

 instances, to the advantage of nomenclature. 



The following specimens in Herb. Melb. belong to E. Gunnii, 

 var. acervula, and were at one time labelled E. Stuartiana by 

 Mueller. 



a. •' White Gum of Mt. Macedon, F. Mueller 1852." 



b. An identical specimen from " Barwon, 1853," has the label 

 "^. Stuartiana, formerly labelled E. Gunnii,^^ showing that 

 Mueller labelled the plant Gunnii, then Stuartiana (and finally 

 Gunnii). 



G. BuUarook Ranges, Ballarat. 

 d. Curdie's Inlet, 1874. 



"^. Stuartiana, one of the white gum-trees. In moist localities, 

 as well in plains as ranges. A tree of an enormous size in Vic- 

 toria, perhaps only surpassed by the Eucalyptus amygdalina and 

 the Karri Eucalypt of West Australia (E. diversicolor or E. 

 colossea).'' (Mueller in Official Record, Intercol. Exhib. Melb. 

 1866-7, p. 222). 



" One of the White Gum trees of the eastern parts of South 

 Australia, Victoria, Tasmania and the south of New South Wales; 

 called, strange to say, the Apple-tree about Dandenong ; the 

 Water Gum-tree of Tasmania may belong to the same species; it 

 is designated locally with still other names. The bark of this 

 often very big tree furnishes good material for packing paper, 

 and, like others, for paste board " (ib. p. 246). 



Following are specimens which were collected by Oldfield. 

 They are labelled : — 



a. " ^. Stuartiana, 'Bed Gum,' Jericho, Tasmania." 



b. "Hill near Lake Tiberias, Tasmania"; the suckers of this 

 specimen are labelled E. viminalis. 



c. O'Brien's Bridge, Tasmania." 



All these specimens agree, in every particular, with E. Gunnii, 

 Hook. f. var. acervula. 



''E. Stuartiana, F.v.M., Marshall's Plains, Flinders' Island. 

 A. Simson (573), June 1877 " (W. W. Spicer in herb. Oxon.).
