Black currant

Ripe purple-black fruit eaten from kudjewk to yekke. They are sweet and much sought after. The flesh stains the lips and mouth purple; purple dye made from boiling or soaking fruit in water for colouring pandanus fibre for manufacturing baskets and string bags; sought after by many birds and is also eaten by dingos (nakarndeken / dalkken) and wallabies.
The name an-kurlbay literally means 'having blood' as the juice of the berries is dark red.
One of the Kundedjnjenghmi terms is "an-kurbayi" which  literally means 'having blood' as the juice ofthe berries is dark red. The plant is associated with the blood of kangaroos and a 'clever men' would use the juice of the fruit in sorcery rituals to spray on tracks to make the legs and joints of a hunted kangaroo seize up making it easier for the hunter to catch his game 

Two popular sites for gathering these fruits in late wet season are Bilinjdje on the Tomkinson RIver flood plain and Kakunidjdji near Marrkolidjban.
