These necklaces are made with seeds collected from Erythrina vespertilio, often familiarly named “bean trees”. It is a softwood tree that was traditionally used to make coolamon and shields. Its bark is also used as a traditional medicine.
The seeds known as ininta once collected are pierced with a metal string, often shaped for its use, that is placed on hot coals. It is a fastidious work that necessitates craftmanship. Then these seeds are connected with a string, sometimes handmade, to produce a smart combination of different coloured-seeds.
This seeds name in Warumungu is ajurrujurru. Mudburra called them kajura but this tree does not grow as far as Elliott. Alyawarr from Epenarra and Canteen Creek called these seeds inernt, itnernt.
