Dioecious tree with subterranean stem. Leaves pinnate, leaflets many, linear-lanceolate, mostly entire, twisted at various angles. Female cones lime-green, to 30 cm.
The centre of the trunk is used as food. It is the source of starch used for a kind of bread. The centre of the female cones is used as food. The flesh around the female cones is used as food. The stem is buried for some months, then pounded used as food.
