the flowers as capitate, whilst the Barou regards them as shortly 

 pedicillate. 



6. E. saligna (Linnaei Spec. Plant, p. 2, and Sm. Act. Soc. Linn. 

 Lond. 3, p. 285). As the specific name is anything but appro- 

 priate, this tree was supposed to be one of the White or Grrey 

 Grums, and it was not until very recently that Baron Mueller 

 proved that it is really the Blue or Flooded Gum found on the 

 banks of creeks and rivers and occasionally on good soil on the 

 outskirts of forests. White collected specimens of JE. saligna 

 (probably on the creeks between Sydney and Parramatta) as 

 early as VJd^ ; but from the short description in Willdenow, it 

 would be difficult to make out the species : ^^ JE. operciilo conico 

 acuto calyceqiie anguloso suhancipiti, capituUs lateralihus solitariis 

 fructu turhinato, foliis linear i-lanceolat is. ^^ As the shape of the 

 operculum and fruit varies considerably in different localities, 

 and as the leaves vary from ovate-lanceolate to narrow lanceolate, 

 Smith's description is rather calculated to mislead, whilst the 

 term saligna is not by any means suggestive of the ordinary 

 foliage. In the inland forms, the flowers and capsules sometimes 

 bear a resemblance to those of the Bastard Mahogany, and hence 

 Mr. Bentham, who had no opportunity of comparing the trees 

 in their living state, has given the name of Blue Grum to E. 

 hotryoicles, the anthers of which are not unlike those of E. saligna. 

 Though there is some difficulty in arranging all species according 

 to their bark, the smooth bark of the one and the rough bark of 

 the other are in this case a good mark of distinction. 



7. E. hotryoides, (Sm., Act. Soc. Linn., Lond., 3, p. 286), or 

 the Bastard Mahogany of the workmen must have been one of 

 those trees, which, at a very early period, attracted the notice of 

 collectors, as it occurs in sandy places adjacent to the sea near 

 Sydney. It comes under the second division of the older 

 Botanists. As far as the description goes, it is pretty accurate : 

 " E. operculo hemisplicerico suhtnutico, capitulis lateralihus solitariis 

 pedunculis cuneatis compressis, fructu turhinato " ; and also, in
