EUCALYPTUS. 259 



E. haemosto ma, Smith. A "white gum." Illawarra, Xew 

 South Wales to Wide Bay, Queensland. The tree is said by Dr. 

 Bancroft to be plentiful and yield a colourless oil of odour 

 intermediate between that of geranium and peppermint. The 

 yield from fresh leaves being 672 ounces per ton, sp. gr. 0* 880 

 (Maiden). Schimmel says 0-890, and boils from 170^ to 250^.* This 

 oil dihers from all other described eucalyptus oils, and has an 

 odour resembling that of cumin oil. It contains cumin-aldehyde, 

 cymol, and among the oxygenated constituents one having a 

 peppermint odour, probably mentlion. 



E. capiteMata, Smith, found in Victoria and Queensland. 

 This oil has not been examined, but its odour is said to be scarcely 

 distinguishable from that of peppermint. 



E. populifolia, Hook. "Bimbil Box" of Xew South Wales, 

 Queensland and Xorth Australia. The oil from this tree is 

 interesting from the fact that it resembles cajuput more than any 

 other eucalyptus oil. In colour it is bright red. It contains cymin- 

 aldehyde and a fair proportion of cineol. 



E. corymbosa, Smith. The " Bloodwood tree." It is found 

 on the coast of Xew South Wales and South Queensland. This 

 is one of the most suitable of eucalypts for a dry soil. Maiden 

 states the odour of its essential oil to resemble a mixture of lemon 

 and rose, and its taste to be bitter and somewhat camphoraceous. 

 It is colourless, of sp. gr. 0-881 at 15^ C. According to Bosisto, 

 100 lbs of leaves yielded 90 ozs. 3 drs. of oil. It is rich in cineol. 



E. goniocalyx Mueller, one of the trees known as " White 

 Gum." This species forms a very tall tree, and is especially found 

 in humid forests on the mountains. It is unknown in Tasmania, 

 and seems limited to the most fertile districts of Victoria and Xew 

 South Wales. In southern Xew South Wales it is known as " Blue 

 Gum," being sometimes known in Victoria as the " Spotted Gum 

 tree." From the barks of both this and E. corymhosa an excellent 

 paper is manufactured ; its wood being very hard and close grained, 

 is much used for building purposes, but its essential is valueless, 

 except perhaps as a curiosity or for investigation, as it possesses a 

 suffocating, penetrating, unpleasant odour and repulsive taste. In
