Rosales
Red garden roses (Rosa hybrid). Whereas wild roses have only five petals, most hybrid varieties have been bred to produce numerous petals in a wide range of colours.
In the context of the Rosaceae family, which belongs to the order Rosales, stipules are small, leaflike structures that are routinely found at the base of the leaf stalks (petioles).1
Generally, a stipule is defined as either of a pair of small, usually leaflike appendages borne at the base of a leaf's petiole in many plant species. These structures are a common characteristic among members of the rose family, which includes a wide variety of plants ranging from apples and strawberries to the rose itself.21
