Flower Structure
The flowers are composed of an average of 6 petals, white in colour, with stamen a purple/maroon colour. The petals

Pollen Morphology
Pollen/ Average sugar concentration : 18.4% Brix
The pollen was circular in shape and found on the anther. The plant had fairly low amount of nectar present in the flower, but the reasonably high sugar concentration would indicate that this is the primary reward produced by the plant to attract pollination vectors. The low drooping petals and reasonably long stamens are a common adaptation for bird pollination

Carpel and stamen being of the same length makes it more likely for self-pollination to occur. In our flower, there is a distinct difference in length, meaning self pollination can be avoided and variation will be more likely in the plant species.

The carpel extends further down the length of the Agapanthus than meets the eye, and a pollen grain must travel this length to reach the ovule below.

Seeds of the agapanthus are dispersed by wind.
