Castanospermum australe.

Botanical name: 

Castanospermum australe A. Cunn. & Fraser. Leguminosae. Moreton Bay Chestnut.

Australia. Fraser says the fruit is eaten by the natives on all occasions and when roasted has the flavor of a Spanish chestnut. Europeans, from necessity, have subsisted on the fruit for two days, the raw fruit griping but the roasted being innoxious.
