“ Tee-coma” of the aboriginals of the Northern Territory. 
This tree exudes gum copiously. It is in dull, horny-looking, 
roundish lumps, usually about the size of a marble. It requires 
picking, as much of it is dark coloured and inferior. The dull 
appearance is only superficial, for it has a very bright fracture. It 
swells up in water to a large extent, and partly dissolves. The 
soluble portion is clear, and almost colourless. This gum differs 
in behaviour from such of the Acacia gums as are only partially 
soluble in water, in that a few hours after placing it in cold water 
it disintegrates, forming flaky masses, whereas the partially soluble 
Acacia gums, while likewise swelling up considerably, preserve a 
certain amount of cohesion for a day or two,
