Types of Flowers Based on Corolla
- Polypetalous: Flowers having free petals are called polypetalous flowers. For example, rose and camellia are polypetalous flowers.
- Gamopetalous: Flowers belonging to gamopetalous (sympetalous) type have fused or united petals. Bindweed and elderberry flowers have gamopetalous petals.
Types of Flowers Based on Presence of Whorls
- Perfect (Bisexual): Flowers consisting the essential whorls, namely, androecium and gynoecium are called perfect flowers. For example, lily and rose are perfect flowers.
- Imperfect (Unisexual): Those flowers that consist of only one reproductive organ, either the male or female part are known as imperfect or incomplete flowers. Examples of imperfect flowers are those of the cucurbitaceae family.
Types of Flowers Based on Placements of Whorls in Receptacle
- Hypogynous: Flowers coming under this type have petals, sepals, and stamens (androecium) arranged at the base of the ovary (gynoecium) in a convex receptacle. The flowers of tomato are hypogynous type.
- Perigynous: Over here, the sepals, petals, stamens, and ovary lie in the same plane. For example, peach blossoms have perigynous flowers.
- Epigynous: In this flower type, the sepals, petals, and stamens are placed above the ovary. Examples of epigynous type are apple blossoms.
Types of Flowers Based on Pollination
- Anemophilous: Anemophilous flowers are pollinated by means of air or wind. For example, flowers of grasses.
- Hydrophilous: In this type of flowers, mode of pollination is water. For example, flowers of vallisneria (eel grass) and sea grass.
- Entomophilous: Flowers types which pollination occurs by insects are called entomophilous flowers. Example of entomophilous flowers are orchids.
