Lorna Fencer (1924-2006) was a famous Lajamanu painter, from a group of Warlpiri people who were forcibly removed from the Yuendumu settlement in the 1950s in order to relieve the growing population pressures in a very small desert community. Lorna inherited through her family line these very big Warlpiri stories, and in the Yumurrpa site the Ancestors drew out the primal yam from the underground water source. Lorna paints a network or a system that shows the yams, shows the roots and the leaves. She uses very rich colour and she uses the occasional dots around the structure representing the flowers and the seeds of the yam.
