Ripe bignay fruit

The species is dioecious, with male and female flowers growing on separate trees. The flowers have a strong, somewhat unpleasant scent. The staminate flowers are arranged in small bunches and the pistillate flowers grow on long racemes which will become the long strands of fruit. The fruits are spherical and just under a centimetre wide, hanging singly or paired in long, heavy bunches. They are white when immature and gradually turn red, then black.

Each bunch of fruits ripens unevenly, so the fruits in a bunch are all different colors. The skin of the fruit has red juice, while the white pulp has colorless juice. The fruit contains a light-colored seed. The fruit has a sour taste similar to that of the cranberry when immature, and a tart but sweet taste when ripe. This tree is cultivated across its native range and the fruits are most often used for making wine and tea and is also used to make jams and jellies. It is often grown as a backyard fruit tree in Java.

There is an inverse correlation between the ability to taste phenylthiocarbamide and bitterness in A. bunius.[2]
