224 AUSTRALIAN NATIVE PLANTS. 
3. Araucaria Cunninghamii, A7/., N.O., Coniferz, B.FI., vi., 243. 
“ Moreton Bay Pine,” ‘‘Hoop Pine,” “Colonial Pine.” ‘ Coorong” 
of the aboriginals of the Richmond River, New South Wales. ‘‘Cumburtu” 
of those of Brisbane, and ‘‘ Coonam” of those of Wide Bay, Queensland. 
The resin which exudes from this tree is very remarkable, as 
it is transparent and nearly colourless, and that portion of it which 
adheres to the trees hangs from them in pendants, which are 
sometimes three feet long and six to twelve inches broad. (Hill.) 
This tree is very rich in resin, as it flows from every slight 
wound. A sample in the Technological Museum is very much 
like gum Thus or common Frankincense, the product of Pinus 
australis, except that it is paler in colour, having the colour of 
and lustre of amber. Although these pieces have been collected 
some years, and externally are quite hard and very brittle, yet 
internally they are still in a viscid condition, and possess the 
pleasing odour of Canada Balsam, with perhaps a trace of 
creasote. 
Northern New South Wales and Queensland. 
4. Atherosperma moschata, Zadz//., N.O., Monimiacez, B.FI., 
v., 284. 
“* Sassafras.” 
The resin contained in the bark of this tree has been examined 
by Zeyer (Pharm, Viertelj, x., 517), an abstract of whose paper 
appears in Gmelin’s Handbook. The following is his account of 
it. The bark, previously exhausted with water, is exhausted with 
very weak caustic potash ; the solution is allowed to stand till clear, 
and the resin is precipitated by hydrochloric acid. The precipitate 
is indigested with alcohol, the extract evaporated, and the residue 
boiled with water, and dried. Brown-red, melts at 104° C. 
Dissolves easily in caustic alkalies and their carbonates, from 
which it is precipitated by acids, and also in alcohol, but it is 
nearly insoluble in ether. Contains at 100° C, on the average 
69.38 °/, C, 8.85 °/, H, and 21°77 O, corresponding to the formula
