Flowers are solitary (single) or in corymbs (cluster). Calyx is five lobed, either simple or compound. Petals & Sepals are generally five; however Rosa sericea has only four petals and sepals. Carpels are many, inserted at the base of the calyx tube and with simple projecting style and stigma. Fruits are known as hips, contain many seeds and are rich in Vit. C, A1, B2, K & E. Seeds are hard and fresh seeds have dormancy.
