Ovary position

An ovary may be "superior" or "inferior".

When the ovary is distal to the attachment of all the other flower parts, it is considered "superior". The flower below has a superior ovary.

When other flower parts are attached to the "top" of the ovary, or distal end of the ovary, the ovary is considered inferior.

Inferior ovaries result when the bases of the other flower parts (stamens, petals and sepals) are fused to the outside of the ovary, or when the ovary is sunk into the receptacle.
