Exudations

— (a) Astringent: This tree yields a dark brown kino, which (amongst the kinos already known) is perhaps characteristic. When freshly exuded it has much the colour and viscosity of molasses, and has a somewhat vinous odour not easily described. In the course of a day or two it solidifies into a friable mass. It is highly astringent. (b) Saccharine: The Rev. Dr. Woolls first drew attention to the existence of manna in this species. I have seen manna on this tree frequently, but only on the edges of leaves which have been eaten by some insect.

Mr. H. G. Smith,note however, records (and gives a full account of) a saccharine exudation whose origin does not appear to be clear. "When exuding it must have been liquid, as it had run down the tree." The material obtained was more or less mixed with bark and debris, caused by boring beetles. An exudation of this character is very interesting, and I only know of one other instance of the kind, i.e., where a saccharine mass from Eucalyptus Stuartiana, Dalgety, Snowy River, was sent to me a few years ago. Mr. Smith's analysis is ample, but we require further investigation in regard to the physiological aspect, i.e., the way in which sugar in such large quantities has been manufactured, and has exuded from the tissues of the plant.
