aO TASMANIAN EUCALYPTS. 



ovate, or oblong. Flowers usually six or seven in the 

 umbel, tube oblong, operculum rather shorter than the 

 tube, with a central protuberance, which in some speci- 

 mens may be elongated to five millimeitres. Fruit typi- 

 cally obconic, mouth wide, rim broad, valves from sunk 

 to protruding, four to six millimetres broad. 



The type of the species was gathered by Labillardier© 

 ill Tasmania, and the figure in his work on New Holland 

 Flora exactly corresponds with the tree which is very 

 common here. Hooker, who evidently was unacquainted 

 with Labillardier e's figure, mistook the tree for the Euc. 

 acervula of Sieber. Mueller, recognising Hooker's error, 

 fell into worse confusion by sometimes recognising our 

 tree as a form of Euc. gunnii, and at others combining it 

 with his own Euc. stuartiana. E,. T. Baker described 

 a similar form as Euc. palndosa. 



Black Gum, also' known as Swam.jJ Gum and Apple- 

 scented Gum (Euc. stuartiana, F.v.M .). — A medium-sized, 

 widely-spreading tree. Bark sub-fibrous, dark, persistent 

 to the branches. Leaves narrow, lanceolate, often slightly 

 unequal-sided, thick, and often shining; juvenile foliage 

 opposite, sessile, orbicular, to oblong. Flowers small, 

 many in the umbel ; operculum conic. Fruit obcomic, 

 usually under three millimetres diameter, valves protrud- 

 ing- 



The form described above corresponds with specimens 

 sent out by Mueller as typical of the tree described as 

 Eitc. stuartiana in his "Eucalyptographia. " Unfortunately 

 Mueller tried to bring in many other forms under the 

 same name, which led to some obscurity. Deane and 

 Maiden consider the tree, common in Northern Tasmania, 

 and described above, to be distinct from Mueller's tree, 

 and najned it Euc. aggregata. R. T. Baker considers it 

 to differ further, and calls it Euc. roclwayi. 



It may be readily distinguished from Ovate Gum by 

 the fibrous bark, naiTOwer leaves, and smaller fruits.
