What is epipetalous stamen? Epipetalous is a condition in which the stamens are attached to petals of the flowers instead of being inserted directly over the thalamus. For example, Solanum. In some plants like lily sepals and petals are the same which are called perianth and when anther is attached to perianth it called epiphyllous.
