240. EUCALYPTUS AMTGDALINA, Labill. (Narrow-leaved Peppermint 



Tree.) 



a. Balsam. Presented by Mr. J. N. Bosisto, of Melbourne. 



&. Gum. 



c. Volatile oil. P. J. [3] , vol. iii., pp. 23, 43. 

 Note. The leaves and young branches yield 2 to 4 per cent, of volatile 

 oil, which is used in soap manufactories to dilute otto of roses, neroli, 

 and other expensive perfumes. It does not answer so well as the Mallee 

 oil (E. oleosa) for dissolving amber, opal, and Kaurie gum. P. J. [3] . 

 vol. ii., p. 628. The gum is soluble in water, but the solution is turbid 

 when cold. P. J. [3] , vol. ii., p. 103. 



241. EUCALYPTUS FABROBUM, Schlecht. (Stringy Bark Tree.) 



a. Gam. 



Note. The gum is not readily soluble in water. This specimen was 

 presented by Mr. Bosisto. P % J. [3] , vol. ii., p. 103. This species is 

 referred by Bentham to E. obliqua, Herit. 



242. EUCALYPTUS GLOBULA, Labill. (Blue Gum Tree.) 



a. Gum. 



b. Eucalyptol. 



Note. The gum is very astringent, and soluble in water, but the solu- 

 tion is turbid when cold. This specimen was obtained from blue gum 

 trees cultivated in Ceylon. Presented by Mr. A. P. Balkwill, of Plymouth, 

 August, 1873. Dried specimens of the plant are in the Herbarium. 

 Eucalyptol is that portion of the volatile oil which boils regularly at 

 175 F. P. J. [3] , vol. i., p. 78. For micr. structure of leaves, see P. J. 

 [3] , vol. iii., p. 990. For fig. of plant, see Bentley and Trimen, Med. 

 Plants, tab. 109. 



243. EUCALYPTUS MANNIFERA, A. Cunn. 



a. Saccharine exudation. (Australian Manna.) 

 Note. E. viminalis, Labill, yields a similar substance. See Melitose, 

 Gmelin, Ghem., vol. xv., p. 292. Bentham, in the Fl. Aust., refers A. 

 mannifera, A. Cunn, to a form of E. viminalis with large fruit. 



244. EUCALYPTUS RESINIFERA, Lm. 



a. Bark. 



&. Ditto, with, gum attached. 



c. Gum. (Botany Bay Kino.) 



Note. This gum may be recognised by its reddish tint and powdery 

 surface. Its tincture is said to be more liable to deposit pectine than East 

 Indian kino. Botany Bay kino is probably produced by several species 

 of Eucalyptus. Pharmacographia, p. 174. 



245. EUCALYPTUS EC-STRATA, Sclilecht. 



a. Gum. (Red Gum.) 



Note. The name red gum is also sometimes applied to the gum of E. 

 resinifera.
