When the anthers of a Strumaria bidentata flower have ripened and released their pollen, they turn black as in this photo. Soon after this the wilting flowerhead will tilt downwards, maybe from the weight of the developing fruits.

The ripe seeds drop down from the pendulous capsules. This is a different dispersal method to that used in some other of Amaryllidaceae genera where the fruiting head becomes detached and mobile, actively dispersing the seeds (Williamson, 2010; www.rareplants.co.uk; iSpot).
