Usually flowers and fruits as a herb but grows to 1 m or more. All plant parts arise from a subterranean bulb.
Leaves produced after flowering. Leaves basal, arising from an underground bulb. Leaf blades +/- orbicular, reniform or broadly ovate, about 20-30 x 15-35 cm, petioles about 15-60 cm long, +/- erect with a groove on one side.
Inflorescence basal, peduncle about 60-100 cm long. Umbel about 5-25-flowered. Pedicels about 3 cm long. Perianth tube about 3-3.5 cm long, lobes about 3.5 cm long. Staminal filaments free in the upper part but fused into a tube towards the base. Free staminal filaments about 20-25 mm long, anthers about 8-9 mm long. Style about 6.5 cm long, exceeding the stamens.
Fruits globose, about 15-30 mm diam., irregularly dehiscent. 'Seeds' consisting of concentric onion-like (Allium cepa) layers.
One or two cataphylls produced before the first true leaves. At the tenth leaf stage: leaves emerge from below ground level. Leaf blade orbicular or cordate, petiole long, much longer than the leaf blade. Bulb about 1.5-2 cm diam. or larger.
Distribution and Ecology
Occurs in WA, CYP, NEQ and southwards as far as coastal central Queensland. Altitudinal range from near sea level to 800 m. Usually grows in wet sclerophyll or open forest but also found in monsoon forest and some of the drier rain forests. Also occurs in Malesia.
This species forms large colonies in situations from coastal rain forest to vine thickets. An excellent bulb cultivated for the large ornamental leaves and the white flowers.
