From the base of the fruit to its apex, five faint lines may be traced running among the spines.

These form the divisions of the carpels where the fruit can be cut open with a sharp knife, though requiring a considerable exertion of strength.

The five cells found within are of a silken white colour, each filled with an oval-shaped mass of cream-coloured pulp containing several seeds of the size of chestnuts.

The pulp forms the edible portion of the fruit, and its consistence and flavour are both difficult to be described.

Mr Wallace, the celebrated hunter naturalist, thus quaintly describes it:-- "A rich, butter-like custard, highly flavoured with almonds, gives the best general idea of it; but intermingled with it come wafts of flavour that call to mind cream-cheese, onion-sauce, brown-sherry, and other incongruities.
