Describe the arrangement of floral members in relation to their insertion on thalamus.
A flower is described as epigynous, perigynous, or epigynous depending on the position
of its calyx, corolla and androecium (relative to the ovary). Hypogynous flowers possess an
ovary positioned at the top of the thalamus while other floral parts sit below. The ovary is
located on the rim of the thalamus in perigynous flowers, while in China roses, mustards, etc.,
the ovary is situated toward the middle. Plum, rose, peach, etc., are examples of ovary half
inferiors. The thalamus surrounds the ovary in epigynous flowers and forms a fusion with its
wall. Above the ovary, there is another group of floral parts. In the flowers of guava and
cucumber, the ovary is considered inferior.
