§  Polysepalous if sepals are separate

§  Gamosepalous if sepals are fused


§  Corolla –made up of petals (often colourful)

§  Polypetalous if petals are separate

§  Gamopetalous if petals are fused

§  Perianth –formed from sepals and petals together


§  Stamen –male reproductive structures of the flower

§  Made up of anther and filaments (produce pollen grains)

§  Monadelphous if stamens are fused

§  Diadelphous if stamens are separate

§  Pollen –Grains containing the male gametes
