AUSTRALIAN PLANTS. 
By G. Harker, B.Sc: 
[ Abstract. ] 
A NuMBER of Australian plants were examined by the author for 
alkaloidal poisons. Large quantities of material were treated 
in each case in order to detect the presence of small traces. 
The bark and leaves were treated separately, and volatile 
alkaloids were also tested for in each case. The following plants 
were examined :— 
Monime—Daphnandra micrantha, Bentham. This plant has 
been examined by Dr. Bancroft physiologically, and found to 
be active. A considerable quantity of an alkaloid was isolated 
by the author, to which a large number of tests were applied. 
The alkaloid, which, so far as could be seen, was amorphous, 
was present in the bark. In the leaves the presence of a 
glucoside in considerable quantity was detected. 
Caurinee—Cryptocarya obovata, R. Brown. No alkaloid 
present. 
Pittosporee—Pittosporum undulatum, Andrews. No alkaloid 
present. 
Euphorbiacee.—Phyllanthus ferdinandi, J. Mueller. This 
plant contained a small trace of a volatile alkaloid.
