The blackberry tree, Vitex glabrata (family ), is a medium-sized spreading tree with tri-foliolate leaves and delicate cream flowers. This is a riverside tree, found near rivers and streams.

This tree has fleshy drupes that turn purple-black when ripe. This fruit is edible and is highly valued. It comes ripe around the start of the wet season. In the case of big trees you wait until the fruit falls to the ground after it has gone ripe and then you can collect it from the ground.
