Floral Variability

These measurements were taken from 6 Azalea flowers.
They show that there is a noticeable difference between the height of the anther and stigma of approx 12mm, suggesting pollination by small insects such as bees, flies, wasps etc.
This is accentuated by the UV fluorescent

Nectar Information:

Due to centuries of selective breeding, these flowers no longer produce nectar.

Pollen Information

The pollen was found in small sticky bundles on each anther.
It was highly fluorescent under UV light.
Under the 40x optical lense, pollen was viewed as tetrapod shaped, with small motile organisms surrounding them.
