| 1. | Pollen grains are light and non-sticky so that they can be transported in wind currents. | The flowers are large, colourful, fragrant and rich in nectar. |
| 2. | They possess well exposed stamens so that the pollen grains are easily dispersed into wind currents and large feathery stigma to easily trap air-borne pollen grains. Wind-pollinated flowers often have a single ovule in each ovary and numerous flowers packed into an inflorescence. | A number of flowers are clustered into an inflorescence. The flowers pollinated by flies and beetles secrete foul odours to attract these animals. |
