How are the stamen attached to the corolla?
An antisepalous (also called antesepalous) stamen position is one in which the point of stamen attachment is in line with (opposite) the sepals, calyx lobes, or outer whorl of tepals; similarly, alternipetalous means having the stamens positioned between the petals or corolla lobes.
