Explain the following terms:
a) Perigynous flower
b) Hypogynous flower
c) Epigynous flower
a) Perigynous flower: The gynoecium is located in the centre, and other parts of the flower are located on the rim of the thalamus almost at the same level.
Examples: Rose, peach
b) Hypogynous flower: The gynoecium is located at the highest point, i.e. the ovary is superior and the other parts are situated below it.
Examples: China rose, brinjal
c) Epigynous flower: The margin of the thalamus grows over and encloses the ovary completely. The margins of the flower get fused with the other parts of the flower which rise above the ovary.
