Close up of the flower showing the green central band on each tepal

Bulb showing the fibrous neck.

Mature bulbs displaying long neck

The pure white flowers open about an hour after sunset.

By the first morning, the flowers have developed a slight pink tinge.

The inflorescence sometimes opens in succession leading to a contrast of the new and old flowers.

The infructescence develops quickly after fertilization producing sometimes dozens of seeds.

Seeds are irregular in shape due to their development and can range from pea-sized to over 1cm across.

The thin pods split along a the edge to release the narrow seeds, each with a tuft of hair to aid dispersion

The tubers are roundish to discoid in shape usually with a projection from the centre where the annual stems emerge.

Tubers appear to be stoloniferous in habit
