__**Comments:**__

In the flowers examined, the stigma and anthers were in close proximity in that they were only ~1mm apart. This suggests possible self fertilisation. The is supported by the stigmas being below the anthers in the flowers examined.

__**Nectar Characteri**____**zation**__

High sugar content attracts insects but it is unsure if they are a factor in pollination rather than just using the nectar as a food source. Certain flowers were found to have double the nectar volume of other flowers.
