The juice of the leaves and fruit act rapidly on the iris and accommodation of the eye, 
producing a widely dilated pupil in twenty minutes. This was introduced into practice some 
years ago by the late Dr. Joseph Bancroft, and ontinues to be largely used both in Europe and 
Australia. 
The late Rev Dr. Will. Woolls, iu paper on “ The plants of Kurrajong and Tomab (N.S.W.),” 
reports having heard it stated that “ the aborigines make holes in the trunk of this tree and put 
some fluid in them which, when drunk on the following morning, produces stupor.” and that 
“branches of the tree are thrown into pools for the purpose of intoxicating the eels and 
bringing them to the surface.” 
Wood of a light yellow colour, light and firm, easy to work ; useful for cabinet-work, carving,
