Plant species: Unknown Plant Family: Liliaceae Common names: Lily, Lilium Description: White and light pink petals. Centred petals are yellowish with tiger stripes.

Floral morphology and visitations
The plants that were examined were believed to be juvenile due to observations. There was no odour present, small petals that are suitable for insects to use as landing pits. When the flower was examined under UV lights there was no glow. Strangely this does not support our hypothesis of the flowers pollinators as glow under UV light are the main attractors for insects.



The image of the flower shows both male and female sexual structures.

Stigma and anther measurements were missed but if estimation, 1.5-2cm difference with the anther higher than the stigma.

Pollen of flower
The pollens are found to be oval/sickle shape that becomes darker under microscope light. It it slightly translucent.

Nectar of flower
Little nectar was present as we identified through the extraction using a capillary tube with only 4mm of nectar collected. 4mm was the combined nectar for all three flowers. Sugar content was not measured due to errors in our harvesting.

Possible pollinators
With little knowledge of the nectar sugar content and pollen, we came to a conlcusion that this flower could cross pollinate either entomophily or ornithophily. There are no fragrance and the nectar is deep within the flower therefore only a bird could use its beak to extract its food source while touching the anthers and transferring pollen on itself. But there is a possibility that the fragrance had been lost due to long period after picked from a garden because factors such as the colourful petals, sticky stigma, soft petals that only insects could be supported on leads to insect pollination. Self pollination can also occur as the anthers are structured higher than the stigma.

These lillies are classified as monocots and 'perfect' flowers becasue they are bisexual.
