| | Rosaceae |
 | | Flowers of the Rosaceae are marked by the presence of a hypanthium. |
 | | This combination of characters will enable you to recognize all members of the family in northern Utah, so long as you bear in mind that a taxon may differ in one or two ways from the rest of the family and still be included in it. |
 | | The Rosaceae retains several features that are thought to have characterized the earliest flowering plants, e.g., many stamens, simple pistils in most subfamilies, and radially symmetric flowers with separate petals, but the hypanthium is definitely an advancement. |
