Stamens of flower may be united with other members such as petals or among themselves .
When stamens are attached to the petals , they are epipetalous as in brinjal
Epiphyllous when attached to the perianth as in the flower of Lily.
The stamens in a flower may either remain free ( polyandrous) or may be united in varying degrees .
The stamens may be united into bunch or one bundle ( monoadelphous) as in China rose or two bundles (diadelphous) as in pea , or into more than two bundles (polydelphous) as in citrus.
There may be variations in the length of filaments within a flower as in salvia and mustard.
