Five sepals form the inner whorl, next to them are five petals. There are typically five inflorescence on a branch. The stamina are bunched in fives, this model has four sets of stamen. While individual flowers vary in numbers of sets, they are always in multiples of five. Hawthorn (Crategus monogyna) and cherry (Cerasus vulgaris) have similar flowers.
