    240. EocALYPTUS AMTGDALiNA, LaUll. (Nurrow-leaved Peppermint Tree.) a. Balaam. Presented by Mr. J. N. Bosisto, of Melbourne. 1). Gam. c. Volatile oil. p. j. [3], vol. iii., pp. 23, 43. Note.—lhQ leaves 4nd 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 fabrorum, SchlecU. (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. obhqua, Herit. 242. Eucalyptus globula, Lahill. (Blue Ghim Tree.) a. Gum. h. 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 boUs regularly at 175° F. P. J. [3], vol. i., p. 78. For micr. structui-e 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. Gunn. a. Saccharine exudation. (Aiistralian Manna.) Note.—E. viminahs, Lahill, yields a similar substance. See Melitose, Gmelin, Chem., vol. xv., p. 292. Bentham, in the Fl. Aust., refers A. mannifera, A. Gunn, to a form of E. viminalis with large fruit. 244. Eucalyptus kesinifera, Lin. a. Bark. h. Ditto, witb 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 eostbata, SMecht. a. Gum. (Bed Gum.) Note.—The name red gum is also sometimes applied to the gum of E. resinifera. For further information on the various species of Eucalyptus, see P, J.
