What similarities in flower structure are found among the plants in the rose family
emmainna [20.7K]

The rose family is a medium-sized family of flowering plants. The rose family (Rosaceae) is one of the major angiosperm families. The leaves are generally arranged spirally. Flowers of plants in the rose family are generally described as "showy". They are actinomorphic and almost always hermaphroditic.  Rosaceae generally have five sepals, and five petals. They also have many spirally arranged stamens. The bases of the sepals, petals, and stamens are fused together to form a  cup-like structure called a hypanthium. They can be arranged in racemes, spikes, or heads; solitary flowers are rare.
