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

Bulb showing the fibrous neck.

Recently described by Tom McCoy in Cactus and Succulent Journal, 89(6): 276-279.

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 inflorescence begins to open in the early evening and the spadix emits a carrion-like odour to attract pollinators

Fully expanded flower shedding pollen the morning after the inflorescence first opened.

Inflorescences can appear from late October through to late December.

Fully expanded leaf with ripening seedhead.

Ripening berries can range in colour from orange to red and are dispersed by birds such as Bulbils.

The berries generally contain 1 to 2 seeds which are recalcitrant and germinate within several weeks from ripening.

The tubers are generally roundish to depressed globose depending on age and produce rhizomatous offsets as a means of vegetative propagation.
