A succulent herb. It is a perennial plant. The roots are fleshy and form underground storage organs. It grows 90-120 cm high and 50-75 cm wide. Plants form dense clumps of leaves. The leaves are glossy and arrow-shaped. They are 40 cm long. The leaves are on stalks arising from the base of the plant. The stalks can be 40 cm long. The leaf stalks have a sticky sap when broken. The flowers have white spathes and a yellow spadix. The white spathes are funnel shaped with a split down the side. The stalk or spadix in the centre has true flowers are clustered along this. After flowering oval yellow berries form and these have round seed.

Leaves several together; petiole to c. 1.2 m long, glabrous, sheathing in lower ⅓–½; sheath persistent; blade hastosagittate, to c. 60 cm long, dull mid green to somewhat glossy dark green. Inflorescence solitary, rarely 2 together, produced in sequence interspersed with foliage leaves; spathe to c. 25 cm long, trumpet-shaped, with limb spreading and distally reflexed, white to cream, green at base; pistils interspersed with staminodes; male zone golden; lower spathe persistent in fruit, becoming green, limb marcescent.
