'Purrpalanji' (skinny bush banana {Rhyncharrhena linearis}) is a twinning climber with thin leaves and pink-brown flowers. Its bean-like edible pods are long and skinny, and can grow up to 20cm long. It is fire tolerant and grows quickly whenever moisture is available. Like 'yurpali' (bush banana {Marsdenia australis}), all of the plant is eaten aside from the woody stems.

This 'purrpalanji' Jukurrpa (skinny bush banana Dreaming) comes from Pikilyi (Vaughan Springs), a large waterhole and natural spring to the west of Yuendumu, close to Mount Doreen. Napangardi/Napanangka women and Japangardi/Japanagka men are the 'kirda' (owners) of the skinny bush banana Dreaming at Pikilyi. Nangala women and Janjala men are the 'kurdungurlu' (custodians) of this Dreaming.

Napangardi and Napanangka women collect 'purrpalanji' (skinny bush banana) and 'yuparli' (bush banana) around Pikilyi in their 'parraja' (coolamons). They cook the 'purrpalanji' and 'yuparli' in hot ashes to get rid of the acidic taste they can have when eaten raw. The skinny bush banana Dreaming is only associated with a number of different Dreamings. These include 'yuparli Jukurrpa' (bush banana Dreaming), and 'warna-jarra Jukurrpa' (two snake Dreaming). In the two snakes Dreaming story, Napangardi and Napanangka women picked lice off the two snakes living in the waterhole at Pikilyi.

In Walpiri paintings, traditional iconography is used to represent the Jukurrpa and other elements. Curved lines are used to represent the long, skinny edible portion of the 'purrpalanji' (skinny bush banana).
