The stamens differ in terms of their insertion or attachment. They are epipetalous when inserted on the corolla; hypogynous when inserted on the receptacle; perigynous when inserted on the calyx- tube or a structure called the hypanthihum, an outgrowth from the base of the gynoecium axis giving arise to stamens, petals and sepals; epigynous when apparently borne on the ovary. In gamopetalous corollas, epipetalous stamens may be inserted on the tube or on the throat of the corolla and when the stamens arch over so as to meet, they are said to be conniving or connivent. The term hypogynous, perigynous and epigynous are also used to describe the insertion of petals and sepals.
