Examples
The flowers of the Rosaceae family always have some type of hypanthium or at least a floral cup from which the sepals, petals and stamens all arise.
The rims around the outside of the hypanthium contain the calyx lobes or free sepals, petals and either the stamen or multiple stamen that are attached at one or two points.
The anthers are typically two-lobed and attach to the filament either at the base or middle.sfn The hypanthium helps in many ways with the reproduction and cross pollination pathways of most plants.
