The pollinating agents are an insect.

The wind-pollinated flowers comprise light coloured petals, without a pleasant strong smell.

The insect-pollinated flowers comprise brightly coloured petals with a pleasant strong smell.

In wind-pollinated flowers, the produced pollen grains are smaller and lighter in weight, which can be carried by the wind easily.

In insect-pollinated flowers, the produced pollen grains are larger in size, sticky and spiny which helps the insect to carry the pollen grains.

Stigma is feathery or sticky and found hanging out of petals.

Stigma is small and is situated deep inside the petals.

The stamens are long and visible out of petals.

Stamens may be small and hidden inside petals.

The anthers are often seen being supported outside the flower

The anthers are found deep inside the flower.

The filaments found in these flowers are slender and long.

The filaments found in these flowers are strong and short.

These flowers do not produce nectars.
